flatpak — Build, install and run applications and runtimes

Name

flatpak — Build, install and run applications and runtimes

Synopsis

flatpak [OPTION...] {COMMAND}

Description

Flatpak is a tool for managing applications and the runtimes they use. In the Flatpak model, applications can be built and distributed independently from the host system they are used on, and they are isolated from the host system ('sandboxed') to some degree, at runtime.

Flatpak can operate in system-wide or per-user mode. The system-wide data (runtimes, applications and configuration) is located in $prefix/var/lib/flatpak/, and the per-user data is in $HOME/.local/share/flatpak/. Below these locations, there is a local repository in the repo/ subdirectory and installed runtimes and applications are in the corresponding runtime/ and app/ subdirectories.

System-wide remotes can be statically preconfigured by dropping flatpakrepo files into /etc/flatpak/remotes.d/.

In addition to the system-wide installation in $prefix/var/lib/flatpak/, which is always considered the default one unless overridden, more system-wide installations can be defined via configuration files in /etc/flatpak/installations.d/, which must define at least the id of the installation and the absolute path to it. Other optional parameters like DisplayName , Priority or StorageType are also supported.

Flatpak uses OSTree to distribute and deploy data. The repositories it uses are OSTree repositories and can be manipulated with the ostree utility. Installed runtimes and applications are OSTree checkouts.

Basic commands for building flatpaks such as build-init, build and build-finish are included in the flatpak utility. For higher-level build support, see the separate flatpak-builder(1) tool.

Flatpak supports installing from sideload repos. These are partial copies of a repository (generated by flatpak create-usb) that are used as an installation source when offline (and online as a performance improvement). Such repositories are configured by creating symlinks to the sideload sources in the sideload-repos subdirectory of the installation directory (i.e. typically /var/lib/flatpak/sideload-repos or ~/.local/share/flatpak/sideload-repos). Additionally symlinks can be created in /run/flatpak/sideload-repos which is a better location for non-persistent sources (as it is cleared on reboot). These symlinks can point to either the directory given to flatpak create-usb which by default writes to the subpath .ostree/repo, or directly to an ostree repo.

Options

The following global options are understood. Individual commands have their own options.

-h, --help

Show help options and exit.

-v, --verbose

Show debug information during command processing. Use -vv for more detail.

Environment

Besides standard environment variables such as XDG_DATA_DIRS and XDG_DATA_HOME, flatpak is consulting some of its own.

FLATPAK_USER_DIR

The location of the per-user installation. If this is not set, $XDG_DATA_HOME/flatpak is used.

FLATPAK_SYSTEM_DIR

The location of the default system-wide installation. If this is not set, /var/lib/flatpak is used (unless overridden at build time by --localstatedir or --with-system-install-dir).

FLATPAK_SYSTEM_CACHE_DIR

The location where temporary child repositories will be created during pulls into the system-wide installation. If this is not set, a directory in /var/tmp/ is used. This is useful because it is more likely to be on the same filesystem as the system repository (thus increasing the chances for e.g. reflink copying), and we can avoid filling the user's home directory with temporary data.

FLATPAK_CONFIG_DIR

The location of flatpak site configuration. If this is not set, /etc/flatpak is used (unless overridden at build time by --sysconfdir).

FLATPAK_RUN_DIR

The location of flatpak runtime global files. If this is not set, /run/flatpak is used.

Name

flatpak-build-bundle — Create a single-file bundle from a local repository

Synopsis

flatpak build-bundle [OPTION...] LOCATION FILENAME NAME [BRANCH]

Description

Creates a single-file named FILENAME for the application (or runtime) named NAME in the repository at LOCATION . If a BRANCH is specified, this branch of the application is used.

The collection ID set on the repository at LOCATION (if set) will be used for the bundle.

Unless --oci is used, the format of the bundle file is that of an ostree static delta (against an empty base) with some flatpak specific metadata for the application icons and appdata.

Options

The following options are understood:

-h, --help

Show help options and exit.

--runtime

Export a runtime instead of an application.

--arch=ARCH

The arch to create a bundle for. See flatpak --supported-arches for architectures supported by the host.

--repo-url=URL

The URL for the repository from which the application can be updated. Installing the bundle will automatically configure a remote for this URL.

--runtime-repo=URL

The URL for a .flatpakrepo file that contains the information about the repository that supplies the runtimes required by the app.

--gpg-keys=FILE

Add the GPG key from FILE (use - for stdin).

--gpg-homedir=PATH

GPG Homedir to use when looking for keyrings.

--from-commit=COMMIT

The OSTree commit to create a delta bundle from.

--oci

Export to an OCI image instead of a Flatpak bundle.

-v, --verbose

Print debug information during command processing.

--ostree-verbose

Print OSTree debug information during command processing.

Examples

$ flatpak build-bundle /var/lib/flatpak/repo gnome-calculator.flatpak org.gnome.Calculator stable

$ flatpak build-bundle ~/.local/share/flatpak/repo gnome-calculator.flatpak org.gnome.Calculator stable


Name

flatpak-build-commit-from — Create new commits based on existing one (possibly from another repository)

Synopsis

flatpak build-commit-from [OPTION...] DST-REPO DST-REF...

Description

Creates new commits on the DST-REF branch in the DST-REPO , with the contents (and most of the metadata) taken from another branch, either from another repo, or from another branch in the same repository.

The collection ID set on DST-REPO (if set) will be used for the newly created commits.

This command is very useful when you want to maintain a branch with a clean history that has no unsigned or broken commits. For instance, you can import the head from a different repository from an automatic builder when you've verified that it worked. The new commit will have no parents or signatures from the autobuilder, and can be properly signed with the official key.

Any deltas that affect the original commit and that match parent commits in the destination repository are copied and rewritten for the new commit id.

Options

The following options are understood:

-h, --help

Show help options and exit.

--src-repo=SRC-REPO

The (local) repository to pull the source branch from. Defaults to the destination repository.

--src-ref=SRC-REF

The branch to use as the source for the new commit. Defaults to the same as the destination ref, which is useful only if a different source repo has been specified.

--extra-collection-id=COLLECTION-ID

Add an extra collection-ref binding for this collection, in addition to whatever would normally be added due to the destination repository collection id. This option can be used multiple times.

--subset=SUBSET

Mark the commit to be included in the named subset. This will cause the commit to be put in the named subset summary (in addition to the main one), allowing users to see only this subset instead of the whole repo.

--untrusted

The source repostory is not trusted, all objects are copied (not hardlinked) and all checksums are verified.

-s, --subject=SUBJECT

One line subject for the commit message. If not specified, will be taken from the source commit.

-b, --body=BODY

Full description for the commit message. If not specified, will be taken from the source commit.

--update-appstream

Update the appstream branch after the build.

--no-update-summary

Don't update the summary file after the new commit is added. This means the repository will not be useful for serving over http until build-update-repo has been run. This is useful is you want to do multiple repo operations before finally updating the summary.

--force

Create new commit even if the content didn't change from the existing branch head.

--disable-fsync

Don't fsync when writing to the repository. This can result in data loss in exceptional situations, but can improve performance when working with temporary or test repositories.

--gpg-sign=KEYID

Sign the commit with this GPG key. This option can be used multiple times.

--gpg-homedir=PATH

GPG Homedir to use when looking for keyrings

--end-of-life=REASON

Mark build as end-of-life

--end-of-life-rebase=OLDID=NEWID

Mark new refs as end-of-life. Unlike --end-of-life, this one takes an ID that supersedes the current one. By the user's request, the application data may be preserved for the new application. Note, this is actually a prefix match, so if you say org.the.app=org.new.app, then something like org.the.app.Locale will be rebased to org.new.app.Locale.

--timestamp=TIMESTAMP

Override the timestamp of the commit. Use an ISO 8601 formatted date, or NOW for the current time

--disable-fsync

Don't fsync when writing to the repository. This can result in data loss in exceptional situations, but can improve performance when working with temporary or test repositories.

-v, --verbose

Print debug information during command processing.

--ostree-verbose

Print OSTree debug information during command processing.

Examples

To revert a commit to the commit before:

$ flatpak build-commit-from --timestamp=NOW --src-ref=app/org.gnome.gedit/x86_64/master^ repo app/org.gnome.gedit/x86_64/master


Name

flatpak-build-export — Create a repository from a build directory

Synopsis

flatpak build-export [OPTION...] LOCATION DIRECTORY [BRANCH]

Description

Creates or updates a repository with an application build. LOCATION is the location of the repository. DIRECTORY must be a finalized build directory. If BRANCH is not specified, it is assumed to be "master".

If LOCATION exists, it is assumed to be an OSTree repository, otherwise a new OSTree repository is created at this location. The repository can be inspected with the ostree tool.

The contents of DIRECTORY are committed on the branch with name app/APPNAME/ARCH/BRANCH, where ARCH is the architecture of the runtime that the application is using. A commit filter is used to enforce that only the contents of the files/ and export/ subdirectories and the metadata file are included in the commit, anything else is ignored.

When exporting a flatpak to be published to the internet, --collection-id=COLLECTION-ID should be specified as a globally unique reverse DNS value to identify the collection of flatpaks this will be added to. Setting a globally unique collection ID allows the apps in the repository to be shared over peer to peer systems without needing further configuration.

The build-update-repo command should be used to update repository metadata whenever application builds are added to a repository.

Options

The following options are understood:

-h, --help

Show help options and exit.

-s, --subject=SUBJECT

One line subject for the commit message.

-b, --body=BODY

Full description for the commit message.

--collection-id=COLLECTION-ID

Set as the collection ID of the repository. Setting a globally unique collection ID allows the apps in the repository to be shared over peer to peer systems without needing further configuration. If exporting to an existing repository, the collection ID must match the existing configured collection ID for that repository.

--subset=SUBSET

Mark the commit to be included in the named subset. This will cause the commit to be put in the named subset summary (in addition to the main one), allowing users to see only this subset instead of the whole repo.

--arch=ARCH

Specify the architecture component of the branch to export. Only host compatible architectures can be specified; see flatpak --supported-arches for valid values.

--exclude=PATTERN

Exclude files matching PATTERN from the commit. This option can be used multiple times.

--include=PATTERN

Don't exclude files matching PATTERN from the commit, even if they match the --exclude patterns. This option can be used multiple times.

--metadata=FILENAME

Use the specified filename as metadata in the exported app instead of the default file (called metadata). This is useful if you want to commit multiple things from a single build tree, typically used in combination with --files and --exclude.

--files=SUBDIR

Use the files in the specified subdirectory as the file contents, rather than the regular files directory.

--timestamp=DATE

Use the specified ISO 8601 formatted date or NOW, for the current time, in the commit metadata and, if --update-appstream is used, the appstream data.

--end-of-life=REASON

Mark the build as end-of-life. REASON is a message that may be shown to users installing this build.

--end-of-life-rebase=ID

Mark the build as end-of-life. Unlike --end-of-life, this one takes an ID that supersedes the current one. By the user's request, the application data may be preserved for the new application.

--disable-fsync

Don't fsync when writing to the repository. This can result in data loss in exceptional situations, but can improve performance when working with temporary or test repositories.

--update-appstream

Update the appstream branch after the build.

--no-update-summary

Don't update the summary file after the new commit is added. This means the repository will not be useful for serving over http until build-update-repo has been run. This is useful is you want to do multiple repo operations before finally updating the summary.

--gpg-sign=KEYID

Sign the commit with this GPG key. This option can be used multiple times.

--gpg-homedir=PATH

GPG Homedir to use when looking for keyrings

-r, --runtime

Export a runtime instead of an app (this uses the usr subdir as files).

-v, --verbose

Print debug information during command processing.

--ostree-verbose

Print OSTree debug information during command processing.

Name

flatpak-build-finish — Finalize a build directory

Synopsis

flatpak build-finish [OPTION...] DIRECTORY

Description

Finalizes a build directory, to prepare it for exporting. DIRECTORY is the name of the directory.

The result of this command is that desktop files, icons, D-Bus service files, and AppStream metainfo files from the files subdirectory are copied to a new export subdirectory. In the metadata file, the command key is set in the [Application] group, and the supported keys in the [Environment] group are set according to the options.

As part of finalization you can also specify permissions that the app needs, using the various options specified below. Additionally during finalization the permissions from the runtime are inherited into the app unless you specify --no-inherit-permissions

You should review the exported files and the application metadata before creating and distributing an application bundle.

It is an error to run build-finish on a directory that has not been initialized as a build directory, or has already been finalized.

Options

The following options are understood:

-h, --help

Show help options and exit.

--command=COMMAND

The command to use. If this option is not specified, the first executable found in files/bin is used.

Note that the command is used when the application is run via flatpak run, and does not affect what gets executed when the application is run in other ways, e.g. via the desktop file or D-Bus activation.

--require-version=MAJOR.MINOR.MICRO

Require this version or later of flatpak to install/update to this build.

--share=SUBSYSTEM

Share a subsystem with the host session. This updates the [Context] group in the metadata. SUBSYSTEM must be one of: network, ipc. This option can be used multiple times.

--unshare=SUBSYSTEM

Don't share a subsystem with the host session. This updates the [Context] group in the metadata. SUBSYSTEM must be one of: network, ipc. This option can be used multiple times.

--socket=SOCKET

Expose a well-known socket to the application. This updates the [Context] group in the metadata. SOCKET must be one of: x11, wayland, fallback-x11, pulseaudio, system-bus, session-bus, ssh-auth, pcsc, cups, gpg-agent. This option can be used multiple times.

The fallback-x11 option makes the X11 socket available only if there is no Wayland socket. This option was introduced in 0.11.3. To support older Flatpak releases, specify both x11 and fallback-x11. The fallback-x11 option takes precedence when both are supported.

--nosocket=SOCKET

Don't expose a well known socket to the application. This updates the [Context] group in the metadata. SOCKET must be one of: x11, wayland, fallback-x11, pulseaudio, system-bus, session-bus, ssh-auth, pcsc, cups, gpg-agent. This option can be used multiple times.

--device=DEVICE

Expose a device to the application. This updates the [Context] group in the metadata. DEVICE must be one of: dri, input, kvm, shm, all. This option can be used multiple times.

--nodevice=DEVICE

Don't expose a device to the application. This updates the [Context] group in the metadata. DEVICE must be one of: dri, input, kvm, shm, all. This option can be used multiple times.

--allow=FEATURE

Allow access to a specific feature. This updates the [Context] group in the metadata. FEATURE must be one of: devel, multiarch, bluetooth, canbus, per-app-dev-shm. This option can be used multiple times.

The devel feature allows the application to access certain syscalls such as ptrace(), and perf_event_open().

The multiarch feature allows the application to execute programs compiled for an ABI other than the one supported natively by the system. For example, for the x86_64 architecture, 32-bit x86 binaries will be allowed as well.

The bluetooth feature allows the application to use bluetooth (AF_BLUETOOTH) sockets. Note, for bluetooth to fully work you must also have network access.

The canbus feature allows the application to use canbus (AF_CAN) sockets. Note, for this work you must also have network access.

The per-app-dev-shm feature shares a single instance of /dev/shm between the application, any unrestricted subsandboxes that it creates, and any other instances of the application that are launched while it is running.

--disallow=FEATURE

Disallow access to a specific feature. This updates the [Context] group in the metadata. FEATURE must be one of: devel, multiarch, bluetooth, canbus, per-app-dev-shm. This option can be used multiple times.

--filesystem=FS

Allow the application access to a subset of the filesystem. This updates the [Context] group in the metadata. FS can be one of: home, host, host-os, host-etc, xdg-desktop, xdg-documents, xdg-download, xdg-music, xdg-pictures, xdg-public-share, xdg-templates, xdg-videos, xdg-run, xdg-config, xdg-cache, xdg-data, an absolute path, or a homedir-relative path like ~/dir or paths relative to the xdg dirs, like xdg-download/subdir. The optional :ro suffix indicates that the location will be read-only. The optional :create suffix indicates that the location will be read-write and created if it doesn't exist. This option can be used multiple times. See the "[Context] filesystems" list in flatpak-metadata(5) for details of the meanings of these filesystems.

--nofilesystem=FILESYSTEM

Remove access to the specified subset of the filesystem from the application. This overrides to the Context section from the application metadata. FILESYSTEM can be one of: home, host, host-os, host-etc, xdg-desktop, xdg-documents, xdg-download, xdg-music, xdg-pictures, xdg-public-share, xdg-templates, xdg-videos, an absolute path, or a homedir-relative path like ~/dir. This option can be used multiple times.

--add-policy=SUBSYSTEM.KEY=VALUE

Add generic policy option. For example, "--add-policy=subsystem.key=v1 --add-policy=subsystem.key=v2" would map to this metadata:

[Policy subsystem]
key=v1;v2;

This option can be used multiple times.

--remove-policy=SUBSYSTEM.KEY=VALUE

Remove generic policy option. This option can be used multiple times.

--env=VAR=VALUE

Set an environment variable in the application. This updates the [Environment] group in the metadata. This overrides to the Context section from the application metadata. This option can be used multiple times.

--unset-env=VAR

Unset an environment variable in the application. This updates the unset-environment entry in the [Context] group of the metadata. This option can be used multiple times.

--env-fd=FD

Read environment variables from the file descriptor FD, and set them as if via --env. This can be used to avoid environment variables and their values becoming visible to other users.

Each environment variable is in the form VAR=VALUE followed by a zero byte. This is the same format used by env -0 and /proc/*/environ.

--own-name=NAME

Allow the application to own the well known name NAME on the session bus. If NAME ends with .*, it allows the application to own all matching names. This updates the [Session Bus Policy] group in the metadata. This option can be used multiple times.

--talk-name=NAME

Allow the application to talk to the well known name NAME on the session bus. If NAME ends with .*, it allows the application to talk to all matching names. This updates the [Session Bus Policy] group in the metadata. This option can be used multiple times.

--system-own-name=NAME

Allow the application to own the well known name NAME on the system bus. If NAME ends with .*, it allows the application to own all matching names. This updates the [System Bus Policy] group in the metadata. This option can be used multiple times.

--system-talk-name=NAME

Allow the application to talk to the well known name NAME on the system bus. If NAME ends with .*, it allows the application to talk to all matching names. This updates the [System Bus Policy] group in the metadata. This option can be used multiple times.

--persist=FILENAME

If the application doesn't have access to the real homedir, make the (homedir-relative) path FILENAME a bind mount to the corresponding path in the per-application directory, allowing that location to be used for persistent data.

If the application doesn't have access to the real homedir, make the (homedir-relative) path FILENAME a bind mount to the corresponding path in the per-application directory, allowing that location to be used for persistent data. This overrides to the Context section from the application metadata. This option can be used multiple times.

--sdk-dir=DIR

Normally if there is a usr directory in the build dir, this is used for the runtime files (this can be created by --writable-sdk or --type=runtime arguments to build-init). If you specify --sdk-dir, this directory will be used instead. Use this if you passed --sdk-dir to build-init.

--readonly

Mount the normally writable destination directories read-only. This can be useful if you want to run something in the sandbox but guarantee that it doesn't affect the build results. For example tests.

--metadata=FILE

Use the specified filename as metadata in the exported app instead of the default file (called metadata). This is useful if you build multiple things from a single build tree (such as both a platform and a sdk).

--log-session-bus

Log session bus traffic. This can be useful to see what access you need to allow in your D-Bus policy.

--log-system-bus

Log system bus traffic. This can be useful to see what access you need to allow in your D-Bus policy.

Name

flatpak-config — Manage configuration

Synopsis

flatpak config [OPTION...]

flatpak config [OPTION...] --set KEY VALUE

flatpak config [OPTION...] --unset|--get KEY

Description

The flatpak config command shows or modifies the configuration of a flatpak installation. The following keys are supported:

languages

The languages that are included when installing Locale extensions. The value is a semicolon-separated list of two-letter language codes, or one of the special values * or all. If this key is unset, flatpak defaults to including the extra-languages key and the current locale.

extra-languages

This key is used when languages is not set, and it defines extra locale extensions on top of the system configured languages. The value is a semicolon-separated list of locale identifiers (language, optional locale, optional codeset, optional modifier) as documented by setlocale(3) (for example, en;en_DK;zh_HK.big5hkscs;uz_UZ.utf8@cyrillic).

For configuration of individual remotes, see flatpak-remote-modify(1). For configuration of individual applications, see flatpak-override(1).

Options

The following options are understood:

-h, --help

Show help options and exit.

--list

Print all keys and their values.

--set

Set key KEY to VALUE .

--unset

Unset key KEY .

--get

Print value of KEY .

-u, --user

Configure per-user installation.

--system

Configure system-wide installation.

--installation=NAME

Configure the system-wide installation specified by NAME among those defined in /etc/flatpak/installations.d/. Using --installation=default is equivalent to using --system.

-v, --verbose

Print debug information during command processing.

--ostree-verbose

Print OSTree debug information during command processing.

Examples

$ flatpak config --set languages "sv;en;fi"


Name

flatpak-create-usb — Copy apps and/or runtimes onto removable media.

Synopsis

flatpak create-usb [OPTION...] MOUNT-PATH REF...

Description

Copies the specified apps and/or runtimes REF s onto the removable media mounted at MOUNT-PATH , along with all the dependencies and metadata needed for installing them. This is one way of transferring flatpaks between computers that doesn't require an Internet connection. After using this command, the USB drive can be connected to another computer which already has the relevant remote(s) configured, and Flatpak will install or update from the drive offline (see below). If online, the drive will be used as a cache, meaning some objects will be pulled from it and others from the Internet. For this process to work a collection ID must be configured on the relevant remotes on both the source and destination computers, and on the remote server.

On the destination computer one can install from the USB (or any mounted filesystem) using the --sideload-repo option with flatpak install. It's also possible to configure sideload paths using symlinks; see flatpak(1). Flatpak also includes systemd units to automatically sideload from hot-plugged USB drives, but these may or may not be enabled depending on your Linux distribution.

Each REF argument is a full or partial identifier in the flatpak ref format, which looks like "(app|runtime)/ID/ARCH/BRANCH". All elements except ID are optional and can be left out, including the slashes, so most of the time you need only specify ID. Any part left out will be matched against what is installed, and if there are multiple matches an error message will list the alternatives.

By default this looks for both installed apps and runtimes with the given REF , but you can limit this by using the --app or --runtime option.

All REF s must be in the same installation (user, system, or other). Otherwise it's ambiguous which repository metadata refs to put on the USB drive.

By default flatpak create-usb uses .ostree/repo as the destination directory under MOUNT-PATH but if you specify another location using --destination-repo a symbolic link will be created for you in .ostree/repos.d. This ensures that either way the repository will be found by flatpak (and other consumers of libostree) for install/update operations.

Unless overridden with the --system, --user, or --installation options, this command searches both the system-wide installation and the per-user one for REF and errors out if it exists in more than one.

Options

The following options are understood:

-h, --help

Show help options and exit.

-u, --user

Copy refs from the per-user installation.

--system

Copy refs from the default system-wide installation.

--installation=NAME

Copy refs from a system-wide installation specified by NAME among those defined in /etc/flatpak/installations.d/. Using --installation=default is equivalent to using --system.

--app

Assume that all REF s are apps if not explicitly specified.

--runtime

Assume that all REF s are runtimes if not explicitly specified.

--destination-repo=DEST

Create the repository in DEST under MOUNT-PATH , rather than the default location.

--allow-partial

Don't print a warning when exporting partially installed commits, for example locale extensions without all languages. These can cause problems when installing them, for example if the language config is different on the installing side.

-v, --verbose

Print debug information during command processing.

--ostree-verbose

Print OSTree debug information during command processing.

Examples

$ flatpak create-usb /run/media/mwleeds/1a9b4cb2-a7ef-4d9b-91a5-6eaf8fdd2bf6/ com.endlessm.wiki_art.en

Name

flatpak-install — Install an application or runtime

Synopsis

flatpak install [OPTION...] [REMOTE] REF...

flatpak install [OPTION...] [--from|--bundle] LOCATION

Description

Installs an application or runtime. The primary way to install is to specify a REMOTE name as the source and one ore more REF s to specify the application or runtime to install. If REMOTE is omitted, the configured remotes are searched for the first REF and the user is asked to confirm the resulting choice.

Each REF argument is a full or partial identifier in the flatpak ref format, which looks like "(app|runtime)/ID/ARCH/BRANCH". All elements except ID are optional and can be left out, including the slashes, so most of the time you need only specify ID. Any part left out will be matched against what is in the remote, and if there are multiple matches you will be prompted to choose one of them. You will also be prompted with choices if REF doesn't match anything in the remote exactly but is similar to one or more refs in the remote (e.g. "devhelp" is similar to "org.gnome.Devhelp"), but this fuzzy matching behavior is disabled if REF contains any slashes or periods.

By default this looks for both apps and runtimes with the given REF in the specified REMOTE , but you can limit this by using the --app or --runtime option, or by supplying the initial element in the REF .

If REMOTE is a uri or a path (absolute or relative starting with ./) to a local repository, then that repository will be used as the source, and a temporary remote will be created for the lifetime of the REF .

If the specified REMOTE has a collection ID configured on it, Flatpak will search the sideload-repos directories configured either with the --sideload-repo option, or on a per-installation or system-wide basis (see flatpak(1)).

The alternative form of the command (with --from or --bundle) allows to install directly from a source such as a .flatpak single-file bundle or a .flatpakref application description. The options are optional if the first argument has the expected filename extension.

Note that flatpak allows to have multiple branches of an application and runtimes installed and used at the same time. However, only one version of an application can be current, meaning its exported files (for instance desktop files and icons) are visible to the host. The last installed version is made current by default, but this can manually changed with flatpak make-current.

Unless overridden with the --user or the --installation option, this command installs the application or runtime in the default system-wide installation.

Options

The following options are understood:

-h, --help

Show help options and exit.

--bundle

Treat LOCATION as a single-bundle file. This is assumed if the argument ends with .flatpak.

--from

Treat LOCATION as an application description file. This is assumed if the argument ends with .flatpakref.

--reinstall

Uninstall first if already installed.

-u, --user

Install the application or runtime in a per-user installation.

--system

Install the application or runtime in the default system-wide installation.

--installation=NAME

Install the application or runtime in a system-wide installation specified by NAME among those defined in /etc/flatpak/installations.d/. Using --installation=default is equivalent to using --system.

--arch=ARCH

The default architecture to install for, if not given explicitly in the REF . See flatpak --supported-arches for architectures supported by the host.

--subpath=PATH

Install only a subpath of REF . This is mainly used to install a subset of locales. This can be added multiple times to install multiple subpaths.

--gpg-file=FILE

Check bundle signatures with GPG key from FILE (- for stdin).

--no-deploy

Download the latest version, but don't deploy it.

--no-pull

Don't download the latest version, deploy whatever is locally available.

--no-related

Don't download related extensions, such as the locale data.

--no-deps

Don't verify runtime dependencies when installing.

--or-update

Normally install just ignores things that are already installed (printing a warning), but if --or-update is specified it silently turns it into an update operation instead.

--app

Assume that all REF s are apps if not explicitly specified.

--runtime

Assume that all REF s are runtimes if not explicitly specified.

--sideload-repo=PATH

Adds an extra local ostree repo as a source for installation. This is equivalent to using the sideload-repos directories (see flatpak(1)), but can be done on a per-command basis. Any path added here is used in addition to ones in those directories.

--include-sdk

For each app being installed, also installs the SDK that was used to build it. Implies --or-update; incompatible with --no-deps.

--include-debug

For each ref being installed, as well as all dependencies, also installs its debug info. Implies --or-update; incompatible with --no-deps.

-y, --assumeyes

Automatically answer yes to all questions (or pick the most prioritized answer). This is useful for automation.

--noninteractive

Produce minimal output and avoid most questions. This is suitable for use in non-interactive situations, e.g. in a build script.

-v, --verbose

Print debug information during command processing.

--ostree-verbose

Print OSTree debug information during command processing.

Name

flatpak-override — Override application requirements

Synopsis

flatpak override [OPTION...] [APP]

Description

Overrides the application specified runtime requirements. This can be used to grant a sandboxed application more or less resources than it requested.

By default the application gets access to the resources it requested when it is started. But the user can override it on a particular instance by specifying extra arguments to flatpak run, or every time by using flatpak override.

The application overrides are saved in text files residing in $XDG_DATA_HOME/flatpak/overrides in user mode.

If the application ID APP is not specified then the overrides affect all applications, but the per-application overrides can override the global overrides.

Unless overridden with the --user or --installation options, this command changes the default system-wide installation.

Options

The following options are understood:

-h, --help

Show help options and exit.

-u, --user

Update a per-user installation.

--system

Update the default system-wide installation.

--installation=NAME

Updates a system-wide installation specified by NAME among those defined in /etc/flatpak/installations.d/. Using --installation=default is equivalent to using --system.

--share=SUBSYSTEM

Share a subsystem with the host session. This overrides the Context section from the application metadata. SUBSYSTEM must be one of: network, ipc. This option can be used multiple times.

--unshare=SUBSYSTEM

Don't share a subsystem with the host session. This overrides the Context section from the application metadata. SUBSYSTEM must be one of: network, ipc. This option can be used multiple times.

--socket=SOCKET

Expose a well-known socket to the application. This overrides to the Context section from the application metadata. SOCKET must be one of: x11, wayland, fallback-x11, pulseaudio, system-bus, session-bus, ssh-auth, pcsc, cups, gpg-agent. This option can be used multiple times.

--nosocket=SOCKET

Don't expose a well-known socket to the application. This overrides to the Context section from the application metadata. SOCKET must be one of: x11, wayland, fallback-x11, pulseaudio, system-bus, session-bus, ssh-auth, pcsc, cups, gpg-agent. This option can be used multiple times.

--device=DEVICE

Expose a device to the application. This overrides to the Context section from the application metadata. DEVICE must be one of: dri, input, kvm, shm, all. This option can be used multiple times.

--nodevice=DEVICE

Don't expose a device to the application. This overrides to the Context section from the application metadata. DEVICE must be one of: dri, input, kvm, shm, all. This option can be used multiple times.

--allow=FEATURE

Allow access to a specific feature. This updates the [Context] group in the metadata. FEATURE must be one of: devel, multiarch, bluetooth, canbus, per-app-dev-shm. This option can be used multiple times.

See flatpak-build-finish(1) for the meaning of the various features.

--disallow=FEATURE

Disallow access to a specific feature. This updates the [Context] group in the metadata. FEATURE must be one of: devel, multiarch, bluetooth, canbus, per-app-dev-shm. This option can be used multiple times.

--filesystem=FILESYSTEM

Allow the application access to a subset of the filesystem. This overrides to the Context section from the application metadata. FILESYSTEM can be one of: home, host, host-os, host-etc, xdg-desktop, xdg-documents, xdg-download, xdg-music, xdg-pictures, xdg-public-share, xdg-templates, xdg-videos, xdg-run, xdg-config, xdg-cache, xdg-data, an absolute path, or a homedir-relative path like ~/dir or paths relative to the xdg dirs, like xdg-download/subdir. The optional :ro suffix indicates that the location will be read-only. The optional :create suffix indicates that the location will be read-write and created if it doesn't exist. This option can be used multiple times. See the "[Context] filesystems" list in flatpak-metadata(5) for details of the meanings of these filesystems.

--nofilesystem=FILESYSTEM

Undo the effect of a previous --filesystem= FILESYSTEM in the app's manifest or a lower-precedence layer of overrides, and/or remove a previous --filesystem= FILESYSTEM from this layer of overrides. This overrides the Context section of the application metadata. FILESYSTEM can take the same values as for --filesystem, but the :ro and :create suffixes are not used here. This option can be used multiple times.

This option does not prevent access to a more narrowly-scoped --filesystem. For example, if an application has the equivalent of --filesystem=xdg-config/MyApp in its manifest or as a system-wide override, and flatpak override --user --nofilesystem=home as a per-user override, then it will be prevented from accessing most of the home directory, but it will still be allowed to access $XDG_CONFIG_HOME/MyApp.

As a special case, --nofilesystem=host:reset will ignore all --filesystem permissions inherited from the app manifest or a lower-precedence layer of overrides, in addition to having the behaviour of --nofilesystem=host.

--add-policy=SUBSYSTEM.KEY=VALUE

Add generic policy option. For example, "--add-policy=subsystem.key=v1 --add-policy=subsystem.key=v2" would map to this metadata:

[Policy subsystem]
key=v1;v2;

This option can be used multiple times.

--remove-policy=SUBSYSTEM.KEY=VALUE

Remove generic policy option. This option can be used multiple times.

--env=VAR=VALUE

Set an environment variable in the application. This overrides to the Context section from the application metadata. This option can be used multiple times.

--unset-env=VAR

Unset an environment variable in the application. This overrides the unset-environment entry in the [Context] group of the metadata, and the [Environment] group. This option can be used multiple times.

--env-fd=FD

Read environment variables from the file descriptor FD, and set them as if via --env. This can be used to avoid environment variables and their values becoming visible to other users.

Each environment variable is in the form VAR=VALUE followed by a zero byte. This is the same format used by env -0 and /proc/*/environ.

--own-name=NAME

Allow the application to own the well-known name NAME on the session bus. This overrides to the Context section from the application metadata. This option can be used multiple times.

--talk-name=NAME

Allow the application to talk to the well-known name NAME on the session bus. This overrides to the Context section from the application metadata. This option can be used multiple times.

--no-talk-name=NAME

Don't allow the application to talk to the well-known name NAME on the session bus. This overrides to the Context section from the application metadata. This option can be used multiple times.

--system-own-name=NAME

Allow the application to own the well known name NAME on the system bus. If NAME ends with .*, it allows the application to own all matching names. This overrides to the Context section from the application metadata. This option can be used multiple times.

--system-talk-name=NAME

Allow the application to talk to the well known name NAME on the system bus. If NAME ends with .*, it allows the application to talk to all matching names. This overrides to the Context section from the application metadata. This option can be used multiple times.

--system-no-talk-name=NAME

Don't allow the application to talk to the well known name NAME on the system bus. If NAME ends with .*, it allows the application to talk to all matching names. This overrides to the Context section from the application metadata. This option can be used multiple times.

--persist=FILENAME

If the application doesn't have access to the real homedir, make the (homedir-relative) path FILENAME a bind mount to the corresponding path in the per-application directory, allowing that location to be used for persistent data. This overrides to the Context section from the application metadata. This option can be used multiple times.

--reset

Remove overrides. If an APP is given, remove the overrides for that application, otherwise remove the global overrides.

--show

Shows overrides. If an APP is given, shows the overrides for that application, otherwise shows the global overrides.

-v, --verbose

Print debug information during command processing.

--ostree-verbose

Print OSTree debug information during command processing.

Examples

$ flatpak override --nosocket=wayland org.gnome.gedit

Name

flatpak-remote-add — Add a remote repository

Synopsis

flatpak remote-add [OPTION...] NAME LOCATION

Description

Adds a remote repository to the flatpak repository configuration. NAME is the name for the new remote, and LOCATION is a url or pathname. The LOCATION is either a flatpak repository, or a .flatpakrepo file which describes a repository. In the former case you may also have to specify extra options, such as the gpg key for the repo.

Unless overridden with the --user or --installation options, this command changes the default system-wide installation.

Options

The following options are understood:

-h, --help

Show help options and exit.

--from

Assume the URI is a .flatpakrepo file rather than the repository itself. This is enabled by default if the extension is .flatpakrepo, so generally you don't need this option.

-u, --user

Modify the per-user configuration.

--system

Modify the default system-wide configuration.

--installation=NAME

Modify a system-wide installation specified by NAME among those defined in /etc/flatpak/installations.d/. Using --installation=default is equivalent to using --system.

--no-gpg-verify

Disable GPG verification for the added remote.

--prio=PRIO

Set the priority for the remote. Default is 1, higher is more prioritized. This is mainly used for graphical installation tools. It is also used when searching for a remote to provide an app's runtime. The app's origin is checked before other remotes with the same priority.

--subset=SUBSET

Limit the refs available from the remote to those that are part of the named subset.

--no-enumerate

Mark the remote as not enumerated. This means the remote will not be used to list applications, for instance in graphical installation tools.

--no-use-for-deps

Mark the remote as not to be used for automatic runtime dependency resolution.

--if-not-exists

Do nothing if the provided remote already exists.

--disable

Disable the added remote.

--title=TITLE

A title for the remote, e.g. for display in a UI.

--comment=COMMENT

A single-line comment for the remote, e.g. for display in a UI.

--description=DESCRIPTION

A full-paragraph description for the remote, e.g. for display in a UI.

--homepage=URL

URL for a website for the remote, e.g. for display in a UI.

--icon=URL

URL for an icon for the remote, e.g. for display in a UI.

--default-branch=BRANCH

A default branch for the remote, mainly for use in a UI.

--filter=PATH

Add a local filter to the remote. A filter file is a list of lines, each file starting with "allow" or "deny", and then a glob for the ref to allow or disallow. The globs specify a partial ref (i.e. you can leave out trailing parts which will then match everything), but otherwise only "*" is special, matching anything in that part of the ref.

By default all refs are allowed, but if a ref matches a deny rule it is disallowed unless it specifically matches an allow rule. This means you can use this to implement both allowlisting and blocklisting.

Here is an example filter file:

# This is an allowlist style filter as it denies all first
deny *
allow runtime/org.freedesktop.*
allow org.some.app/arm
allow org.signal.Signal/*/stable
allow org.signal.Signal.*/*/stable

--gpg-import=FILE

Import gpg keys from the specified keyring file as trusted for the new remote. If the file is - the keyring is read from standard input.

--authenticator-name=NAME

Specify the authenticator to use for the remote.

--authenticator-option=KEY=VALUE

Specify an authenticator option for the remote.

--authenticator-install

Enable auto-installation of authenticator.

--no-authenticator-install

Disable auto-installation of authenticator.

--no-follow-redirect

Do not follow xa.redirect-url defined in the summary file.

-v, --verbose

Print debug information during command processing.

--ostree-verbose

Print OSTree debug information during command processing.

Synopsis

flatpak remote-info [OPTION...] REMOTE REF

Description

Shows information about the runtime or application REF from the remote repository with the name REMOTE . You can find all configured remote repositories with flatpak remotes.

By default, the output is formatted in a friendly format. If you specify one of the --show-… options, the output is instead formatted in a machine-readable format.

Unless overridden with the --system, --user, or --installation options, this command uses either the default system-wide installation or the per-user one, depending on which has the specified REMOTE .

Options

The following options are understood:

-h, --help

Show help options and exit.

-u, --user

Use the per-user configuration.

--system

Use the default system-wide configuration.

--installation=NAME

Use a system-wide installation specified by NAME among those defined in /etc/flatpak/installations.d/. Using --installation=default is equivalent to using --system.

--cached

Prefer to use locally cached information if possible, even though it may be out of date. This is faster, but risks returning stale information. Also, some information is not cached so will not be available.

--runtime

Assume that REF is a runtime if not explicitly specified.

--app

Assume that REF is an app if not explicitly specified.

--arch=ARCH

The default architecture to look for, if not given explicitly in the REF . See flatpak --supported-arches for architectures supported by the host.

Name

flatpak-remote-ls — Show available runtimes and applications

Synopsis

flatpak remote-ls [OPTION...] [REMOTE]

Description

Shows runtimes and applications that are available in the remote repository with the name REMOTE , or all remotes if one isn't specified. You can find all configured remote repositories with flatpak remotes.

REMOTE can be a file:// URI pointing to a local repository instead of a remote name.

Unless overridden with the --system, --user, or --installation options, this command uses either the default system-wide installation or the per-user one, depending on which has the specified REMOTE .

Options

The following options are understood:

-h, --help

Show help options and exit.

-u, --user

Use the per-user configuration.

--system

Use the default system-wide configuration.

--installation=NAME

Use a system-wide installation specified by NAME among those defined in /etc/flatpak/installations.d/. Using --installation=default is equivalent to using --system.

--cached

Prefer to use locally cached information if possible, even though it may be out of date. This is faster, but risks returning stale information.

-d, --show-details

Show arches, branches and commit ids, in addition to the names. Equivalent to --columns=all.

--runtime

Show only runtimes, omit applications.

--app

Show only applications, omit runtimes.

--all, -a

Show everything. By default locale and debug extensions as well as secondary arches when the primary arch is available are hidden.

--updates

Show only those which have updates available.

--arch=ARCH

Show only those matching the specified architecture. By default, only supported architectures are shown. Use --arch=* to show all architectures. See flatpak --supported-arches for architectures supported by the host.

-v, --verbose

Print debug information during command processing.

--ostree-verbose

Print OSTree debug information during command processing.

--app-runtime=RUNTIME

List applications that use the given runtime

--columns=FIELD,…

Specify what information to show about each ref. You can list multiple fields, or use this option multiple times.

Append :s[tart], :m[iddle], :e[nd] or :f[ull] to column names to change ellipsization.

Fields

The following fields are understood by the --columns option:

name

Show the name

description

Show the application description

application

Show the application or runtime ID

arch

Show the arch

branch

Show the branch

version

Show the version

Name

flatpak-repair — Repair a flatpak installation

Synopsis

flatpak repair [OPTION...]

Description

Repair a flatpak installation by pruning and reinstalling invalid objects. The repair command does all of the following:

  • Scan all locally available refs, removing any that don't correspond to a deployed ref.

  • Verify each commit they point to, removing any invalid objects and noting any missing objects.

  • Remove any refs that had an invalid object, and any non-partial refs that had missing objects.

  • Prune all objects not referenced by a ref, which gets rid of any possibly invalid non-scanned objects.

  • Enumerate all deployed refs and re-install any that are not in the repo (or are partial for a non-subdir deploy).

Note that flatpak repair has to be run with root privileges to operate on the system installation.

An alternative command for repairing OSTree repositories is ostree fsck.

Options

The following options are understood:

-h, --help

Show help options and exit.

-u, --user

Repair per-user installation.

--system

Repair system-wide installation.

--installation=NAME

Repair the system-wide installation specified by NAME among those defined in /etc/flatpak/installations.d/. Using --installation=default is equivalent to using --system .

--dry-run

Only report inconsistencies, don't make any changes

--reinstall-all

Reinstall all refs, regardless of whether they were removed from the repo or not

-v, --verbose

Print debug information during command processing.

--ostree-verbose

Print OSTree debug information during command processing.

Examples

$ sudo flatpak repair

Options

The following options are understood:

-h, --help

Show help options and exit.

--info

Print general information about a local repository.

--branches

List the branches in a local repository.

--metadata=BRANCH

Print metadata for a branch in the repository.

--commits=BRANCH

Show commits and deltas for a branch in the repository.

-v, --verbose

Print debug information during command processing.

--ostree-verbose

Print OSTree debug information during command processing.

Examples

$ flatpak repo --info ~/my-repo


Name

flatpak-run — Run an application or open a shell in a runtime

Synopsis

flatpak run [OPTION...] REF [ARG...]

Description

If REF names an installed application, Flatpak runs the application in a sandboxed environment. Extra arguments are passed on to the application. The current branch and arch of the application is used unless otherwise specified with --branch or --arch. See flatpak-make-current(1).

If REF names a runtime, a shell is opened in the runtime. This is useful for development and testing. If there is ambiguity about which branch to use, you will be prompted to choose. Use --branch to avoid this. The primary arch is used unless otherwise specified with --arch.

By default, Flatpak will look for the application or runtime in the per-user installation first, then in all system installations. This can be overridden with the --user, --system and --installation options.

Flatpak creates a sandboxed environment for the application to run in by mounting the right runtime at /usr and a writable directory at /var, whose content is preserved between application runs. The application itself is mounted at /app.

The details of the sandboxed environment are controlled by the application metadata and various options like --share and --socket that are passed to the run command: Access is allowed if it was requested either in the application metadata file or with an option and the user hasn't overridden it.

The remaining arguments are passed to the command that gets run in the sandboxed environment. See the --file-forwarding option for handling of file arguments.

Environment variables are generally passed on to the sandboxed application, with certain exceptions. The application metadata can override environment variables, as well as the --env option. Apart from that, Flatpak always unsets or overrides the following variables, since their session values are likely to interfere with the functioning of the sandbox:

PATH
LD_LIBRARY_PATH
XDG_CONFIG_DIRS
XDG_DATA_DIRS
XDG_RUNTIME_DIR
SHELL
TEMP
TEMPDIR
TMP
TMPDIR
PYTHONPATH
PERLLIB
PERL5LIB
XCURSOR_PATH
KRB5CCNAME
XKB_CONFIG_ROOT
GIO_EXTRA_MODULES
GDK_BACKEND
VK_DRIVER_FILES
VK_ICD_FILENAMES

Also several environment variables with the prefix "GST_" that are used by gstreamer are unset (since Flatpak 1.12.5).

Flatpak also overrides the XDG environment variables to point sandboxed applications at their writable filesystem locations below ~/.var/app/$APPID/:

XDG_DATA_HOME
XDG_CONFIG_HOME
XDG_CACHE_HOME
XDG_STATE_HOME (since Flatpak 1.13)

Apps can use the --persist=.local/state and --unset-env=XDG_STATE_HOME options to get a Flatpak 1.13-compatible ~/.local/state on older versions of Flatpak.

The host values of these variables are made available inside the sandbox via these HOST_-prefixed variables:

HOST_XDG_DATA_HOME
HOST_XDG_CONFIG_HOME
HOST_XDG_CACHE_HOME
HOST_XDG_STATE_HOME (since Flatpak 1.13)

Flatpak sets the environment variable FLATPAK_ID to the application ID of the running app.

Flatpak also bind-mounts as read-only the host's /etc/os-release (if available, or /usr/lib/os-release as a fallback) to /run/host/os-release in accordance with the os-release specification.

If parental controls support is enabled, flatpak will check the current user’s parental controls settings, and will refuse to run an app if it is blocklisted for the current user.

Options

The following options are understood:

-h, --help

Show help options and exit.

-u, --user

Look for the application and runtime in per-user installations.

--system

Look for the application and runtime in the default system-wide installations.

--installation=NAME

Look for the application and runtime in the system-wide installation specified by NAME among those defined in /etc/flatpak/installations.d/. Using --installation=default is equivalent to using --system.

-v, --verbose

Print debug information during command processing.

--ostree-verbose

Print OSTree debug information during command processing.

--arch=ARCH

The architecture to run. See flatpak --supported-arches for architectures supported by the host.

--command=COMMAND

The command to run instead of the one listed in the application metadata.

--cwd=DIR

The directory to run the command in. Note that this must be a directory inside the sandbox.

--branch=BRANCH

The branch to use.

-d, --devel

Use the devel runtime that is specified in the application metadata instead of the regular runtime, and use a seccomp profile that is less likely to break development tools.

--runtime=RUNTIME

Use this runtime instead of the one that is specified in the application metadata. This is a full tuple, like for example org.freedesktop.Sdk/x86_64/1.2 , but partial tuples are allowed. Any empty or missing parts are filled in with the corresponding values specified by the app.

--runtime-version=VERSION

Use this version of the runtime instead of the one that is specified in the application metadata. This overrides any version specified with the --runtime option.

--share=SUBSYSTEM

Share a subsystem with the host session. This overrides the Context section from the application metadata. SUBSYSTEM must be one of: network, ipc. This option can be used multiple times.

--unshare=SUBSYSTEM

Don't share a subsystem with the host session. This overrides the Context section from the application metadata. SUBSYSTEM must be one of: network, ipc. This option can be used multiple times.

--socket=SOCKET

Expose a well known socket to the application. This overrides to the Context section from the application metadata. SOCKET must be one of: x11, wayland, fallback-x11, pulseaudio, system-bus, session-bus, ssh-auth, pcsc, cups, gpg-agent. This option can be used multiple times.

--nosocket=SOCKET

Don't expose a well known socket to the application. This overrides to the Context section from the application metadata. SOCKET must be one of: x11, wayland, fallback-x11, pulseaudio, system-bus, session-bus, ssh-auth, pcsc, cups, gpg-agent. This option can be used multiple times.

--device=DEVICE

Expose a device to the application. This overrides to the Context section from the application metadata. DEVICE must be one of: dri, input, kvm, shm, all. This option can be used multiple times.

--nodevice=DEVICE

Don't expose a device to the application. This overrides to the Context section from the application metadata. DEVICE must be one of: dri, input, kvm, shm, all. This option can be used multiple times.

--allow=FEATURE

Allow access to a specific feature. This overrides to the Context section from the application metadata. FEATURE must be one of: devel, multiarch, bluetooth. This option can be used multiple times.

See flatpak-build-finish(1) for the meaning of the various features.

--disallow=FEATURE

Disallow access to a specific feature. This overrides to the Context section from the application metadata. FEATURE must be one of: devel, multiarch, bluetooth. This option can be used multiple times.

--filesystem=FILESYSTEM

Allow the application access to a subset of the filesystem. This overrides to the Context section from the application metadata. FILESYSTEM can be one of: home, host, host-os, host-etc, xdg-desktop, xdg-documents, xdg-download, xdg-music, xdg-pictures, xdg-public-share, xdg-templates, xdg-videos, xdg-run, xdg-config, xdg-cache, xdg-data, an absolute path, or a homedir-relative path like ~/dir or paths relative to the xdg dirs, like xdg-download/subdir. The optional :ro suffix indicates that the location will be read-only. The optional :create suffix indicates that the location will be read-write and created if it doesn't exist. This option can be used multiple times. See the "[Context] filesystems" list in flatpak-metadata(5) for details of the meanings of these filesystems.

--nofilesystem=FILESYSTEM

Undo the effect of a previous --filesystem= FILESYSTEM in the app's manifest and/or the overrides set up with flatpak-override(1). This overrides the Context section of the application metadata. FILESYSTEM can take the same values as for --filesystem, but the :ro and :create suffixes are not used here. This option can be used multiple times.

This option does not prevent access to a more narrowly-scoped --filesystem. For example, if an application has the equivalent of --filesystem=xdg-config/MyApp in its manifest or as a system-wide override, and flatpak override --user --nofilesystem=home as a per-user override, then it will be prevented from accessing most of the home directory, but it will still be allowed to access $XDG_CONFIG_HOME/MyApp.

As a special case, --nofilesystem=host:reset will ignore all --filesystem permissions inherited from the app manifest or flatpak-override(1), in addition to having the behaviour of --nofilesystem=host.

--add-policy=SUBSYSTEM.KEY=VALUE

Add generic policy option. For example, "--add-policy=subsystem.key=v1 --add-policy=subsystem.key=v2" would map to this metadata:

[Policy subsystem]
key=v1;v2;

This option can be used multiple times.

--remove-policy=SUBSYSTEM.KEY=VALUE

Remove generic policy option. This option can be used multiple times.

--env=VAR=VALUE

Set an environment variable in the application. This overrides to the Context section from the application metadata. This option can be used multiple times.

--unset-env=VAR

Unset an environment variable in the application. This overrides the unset-environment entry in the [Context] group of the metadata, and the [Environment] group. This option can be used multiple times.

--env-fd=FD

Read environment variables from the file descriptor FD, and set them as if via --env. This can be used to avoid environment variables and their values becoming visible to other users.

Each environment variable is in the form VAR=VALUE followed by a zero byte. This is the same format used by env -0 and /proc/*/environ.

--own-name=NAME

Allow the application to own the well known name NAME on the session bus. If NAME ends with .*, it allows the application to own all matching names. This overrides to the Context section from the application metadata. This option can be used multiple times.

--talk-name=NAME

Allow the application to talk to the well known name NAME on the session bus. If NAME ends with .*, it allows the application to talk to all matching names. This overrides to the Context section from the application metadata. This option can be used multiple times.

--no-talk-name=NAME

Don't allow the application to talk to the well known name NAME on the session bus. If NAME ends with .*, it allows the application to talk to all matching names. This overrides to the Context section from the application metadata. This option can be used multiple times.

--system-own-name=NAME

Allow the application to own the well known name NAME on the system bus. If NAME ends with .*, it allows the application to own all matching names. This overrides to the Context section from the application metadata. This option can be used multiple times.

--system-talk-name=NAME

Allow the application to talk to the well known name NAME on the system bus. If NAME ends with .*, it allows the application to talk to all matching names. This overrides to the Context section from the application metadata. This option can be used multiple times.

--system-no-talk-name=NAME

Don't allow the application to talk to the well known name NAME on the system bus. If NAME ends with .*, it allows the application to talk to all matching names. This overrides to the Context section from the application metadata. This option can be used multiple times.

--persist=FILENAME

If the application doesn't have access to the real homedir, make the (homedir-relative) path FILENAME a bind mount to the corresponding path in the per-application directory, allowing that location to be used for persistent data. This overrides to the Context section from the application metadata. This option can be used multiple times.

--no-session-bus

Run this instance without the filtered access to the session dbus connection. Note, this is the default when run with --sandbox.

--session-bus

Allow filtered access to the session dbus connection. This is the default, except when run with --sandbox.

In sandbox mode, even if you allow access to the session bus the sandbox cannot talk to or own the application ids (org.the.App.*) on the bus (unless explicitly added), only names in the .Sandboxed subset (org.the.App.Sandboxed.* and org.mpris.MediaPlayer2.org.the.App.Sandboxed.*).

--no-a11y-bus

Run this instance without the access to the accessibility bus. Note, this is the default when run with --sandbox.

--a11y-bus

Allow access to the accessibility bus. This is the default, except when run with --sandbox.

--sandbox

Run the application in sandboxed mode, which means dropping all the extra permissions it would otherwise have, as well as access to the session/system/a11y busses and document portal.

--log-session-bus

Log session bus traffic. This can be useful to see what access you need to allow in your D-Bus policy.

--log-system-bus

Log system bus traffic. This can be useful to see what access you need to allow in your D-Bus policy.

-p, --die-with-parent

Kill the entire sandbox when the launching process dies.

--parent-pid=PID

Specifies the pid of the "parent" flatpak, used by --parent-expose-pids and --parent-share-pids.

--parent-expose-pids

Make the processes of the new sandbox visible in the sandbox of the parent flatpak, as defined by --parent-pid.

--parent-share-pids

Use the same process ID namespace for the processes of the new sandbox and the sandbox of the parent flatpak, as defined by --parent-pid. Implies --parent-expose-pids.

--instance-id-fd

Write the instance ID string to the given file descriptor.

--file-forwarding

If this option is specified, the remaining arguments are scanned, and all arguments that are enclosed between a pair of '@@' arguments are interpreted as file paths, exported in the document store, and passed to the command in the form of the resulting document path. Arguments between '@@u' and '@@' are considered uris, and any file: uris are exported. The exports are non-persistent and with read and write permissions for the application.

--app-path=PATH

Instead of mounting the app's content on /app in the sandbox, mount PATH on /app, and the app's content on /run/parent/app. If the app has extensions, they will also be redirected into /run/parent/app, and will not be included in the LD_LIBRARY_PATH inside the sandbox.

--app-path=

As a special case, --app-path= (with an empty PATH) results in an empty directory being mounted on /app.

--usr-path=PATH

Instead of mounting the runtime's files on /usr in the sandbox, mount PATH on /usr, and the runtime's normal files on /run/parent/usr. If the runtime has extensions, they will also be redirected into /run/parent/usr, and will not be included in the LD_LIBRARY_PATH inside the sandbox.

This option will usually only be useful if it is combined with --app-path= and --env=LD_LIBRARY_PATH=....

Name

flatpak-uninstall — Uninstall an application or runtime

Synopsis

flatpak uninstall [OPTION...] [REF...]

Description

Uninstalls an application or runtime. REF is a reference to the application or runtime to uninstall.

Each REF argument is a full or partial identifier in the flatpak ref format, which looks like "(app|runtime)/ID/ARCH/BRANCH". All elements except ID are optional and can be left out, including the slashes, so most of the time you need only specify ID. Any part left out will be matched against what is installed, and if there are multiple matches you will be prompted to choose between them. You will also be prompted if REF doesn't match any installed ref exactly but is similar (e.g. "gedit" is similar to "org.gnome.gedit"), but this fuzzy matching behavior is disabled if REF contains any slashes or periods.

By default this looks for both installed apps and runtimes with the given REF , but you can limit this by using the --app or --runtime option, or by supplying the initial element in the REF .

Normally, this command removes the ref for this application/runtime from the local OSTree repository and purges any objects that are no longer needed to free up disk space. If the same application is later reinstalled, the objects will be pulled from the remote repository again. The --keep-ref option can be used to prevent this.

When --delete-data is specified while removing an app, its data directory in ~/.var/app and any permissions it might have are removed. When --delete-data is used without a REF , all 'unowned' app data is removed.

Unless overridden with the --system, --user, or --installation options, this command searches both the system-wide installation and the per-user one for REF and errors out if it exists in more than one.

Options

The following options are understood:

-h, --help

Show help options and exit.

--keep-ref

Keep the ref for the application and the objects belonging to it in the local repository.

-u, --user

Uninstalls from a per-user installation.

--system

Uninstalls from the default system-wide installation.

--installation=NAME

Uninstalls from a system-wide installation specified by NAME among those defined in /etc/flatpak/installations.d/. Using --installation=default is equivalent to using --system.

--arch=ARCH

The architecture to uninstall, instead of the architecture of the host system. See flatpak --supported-arches for architectures supported by the host.

--all

Remove all refs on the system.

--unused

Remove unused refs on the system.

-y, --assumeyes

Automatically answer yes to all questions. This is useful for automation.

--noninteractive

Produce minimal output and avoid most questions. This is suitable for use in non-interactive situations, e.g. in a build script.

--app

Only look for an app with the given name.

--runtime

Only look for a runtime with the given name.

--no-related

Don't uninstall related extensions, such as the locale data.

Name

flatpak-update — Update an application or runtime

Synopsis

flatpak update [OPTION...] [REF...]

flatpak update [OPTION...] --appstream [REMOTE]

Description

Updates applications and runtimes. REF is a reference to the application or runtime to update. If no REF is given, everything is updated, as well as appstream info for all remotes.

Each REF argument is a full or partial identifier in the flatpak ref format, which looks like "(app|runtime)/ID/ARCH/BRANCH". All elements except ID are optional and can be left out, including the slashes, so most of the time you need only specify ID. Any part left out will be matched against what is installed, and if there are multiple matches an error message will list the alternatives.

By default this looks for both apps and runtimes with the given REF , but you can limit this by using the --app or --runtime option, or by supplying the initial element in the REF .

Normally, this command updates the application to the tip of its branch. But it is possible to check out another commit, with the --commit option.

If the configured remote for a ref being updated has a collection ID configured on it, Flatpak will search the sideload-repos directories configured either with the --sideload-repo option, or on a per-installation or system-wide basis (see flatpak(1)).

Note that updating a runtime is different from installing a different branch, and runtime updates are expected to keep strict compatibility. If an application update does cause a problem, it is possible to go back to the previous version, with the --commit option.

In addition to updates, this command will offer to uninstall any unused end-of-life runtimes. Runtimes that were explicitly installed (not as a dependency) or explicitly pinned (see flatpak-pin(1)) are left installed even if unused and end-of-life.

Unless overridden with the --user, --system or --installation option, this command updates any matching refs in the standard system-wide installation and the per-user one.

Options

The following options are understood:

-h, --help

Show help options and exit.

-u, --user

Update a per-user installation.

--system

Update the default system-wide installation.

--installation=NAME

Updates a system-wide installation specified by NAME among those defined in /etc/flatpak/installations.d/. Using --installation=default is equivalent to using --system.

--arch=ARCH

The architecture to update for. See flatpak --supported-arches for architectures supported by the host.

--subpath=PATH

Install only a subpath of the ref. This is mainly used to install a subset of locales. This can be added multiple times to install multiple subpaths. If this is not specified the subpaths specified at install time are reused.

--commit=COMMIT

Update to this commit, instead of the tip of the branch. You can find commits using flatpak remote-info --log REMOTE REF.

--no-deploy

Download the latest version, but don't deploy it.

--no-pull

Don't download the latest version, deploy whatever is locally available.

--no-related

Don't download related extensions, such as the locale data.

--no-deps

Don't update or install runtime dependencies when installing.

--app

Only look for an app with the given name.

--appstream

Update appstream for REMOTE , or all remotes if no remote is specified.

--runtime

Only look for a runtime with the given name.

--sideload-repo=PATH

Adds an extra local ostree repo as a source for installation. This is equivalent to using the sideload-repos directories (see flatpak(1)), but can be done on a per-command basis. Any path added here is used in addition to ones in those directories.

-y, --assumeyes

Automatically answer yes to all questions (or pick the most prioritized answer). This is useful for automation.

--noninteractive

Produce minimal output and avoid most questions. This is suitable for use in non-interactive situations, e.g. in a build script.

--force-remove

Remove old files even if they're in use by a running application.

-v, --verbose

Print debug information during command processing.

--ostree-verbose

Print OSTree debug information during command processing.

Examples

$ flatpak --user update org.gnome.gedit


Name

flatpak-spawn — Run commands in a sandbox

Synopsis

flatpak-spawn [OPTION...] COMMAND [ARGUMENT...]

Description

Unlike other flatpak commands, flatpak-spawn is available to applications inside the sandbox. It runs COMMAND outside the sandbox: either in another sandbox, or on the host.

When called without --host, flatpak-spawn uses the Flatpak portal to create a copy of the sandbox it was called from, optionally using tighter permissions and optionally the latest version of the app and runtime (see --latest-version).

Options

The following options are understood:

-h, --help

Show help options and exit.

-v, --verbose

Print debug information

--forward-fd=FD

Forward a file descriptor

--clear-env

Run with a clean environment

--watch-bus

Make the spawned command exit if the caller disappears from the session bus

--env=VAR=VALUE

Set an environment variable

--latest-version

Use the latest version of the refs that are used to set up the sandbox

--no-network

Run without network access

--sandbox

Run fully sandboxed. See the documentation for the --sandbox option in flatpak-run(1)

See the --sandbox-expose and --sandbox-expose-ro options for selective file access.

--sandbox-expose=NAME

Expose read-write access to a file in the sandbox.

Note that absolute paths or subdirectories are not allowed. The files must be in the sandbox subdirectory of the instance directory (i.e. ~/.var/app/$APP_ID/sandbox).

This option is useful in combination with --sandbox (otherwise the instance directory is accessible anyway).

--sandbox-expose-ro=NAME

Expose readonly access to a file in the sandbox.

Note that absolute paths or subdirectories are not allowed. The files must be in the sandbox subdirectory of the instance directory (i.e. ~/.var/app/$APP_ID/sandbox).

This option is useful in combination with --sandbox (otherwise the instance directory is accessible anyway).

--host

Run the command unsandboxed on the host. This requires access to the org.freedesktop.Flatpak D-Bus interface.

--directory=DIR

The working directory in which to run the command.

Note that the given directory must exist in the sandbox or, when used in conjunction with --host, on the host.

Examples

$ flatpak-spawn ls /var/run

Name

flatpak-flatpakrepo — Reference to a remote

Description

Flatpak uses flatpakrepo files to share information about remotes. The flatpakrepo file contains enough information to add the remote. Use the flatpak remote-add --from command to do so.

flatpakrepo files may also contain additional information that is useful when displaying a remote to the user, e.g. in an app store.

The filename extension commonly used for flatpakrepo files is .flatpakrepo.

File format

The flatpakrepo file is using the same .ini file format that is used for systemd unit files or application .desktop files.

[Flatpak Repo]

All the information is contained in the [Flatpak Repo] group.

The following keys can be present in this group:

Version (uint64)

The version of the file format, must be 1 if present.

Url (string)

The url for the remote. This key is mandatory.

GPGKey (string)

The base64-encoded gpg key for the remote.

DefaultBranch (string)

The default branch to use for this remote.

Subset (string)

Limit the remote to the named subset of refs.

Title (string)

The title of the remote. This should be a user-friendly name that can be displayed e.g. in an app store.

Comment (string)

A short summary of the remote, for display e.g. in an app store.

Description (string)

A longer description of the remote, for display e.g. in an app store.

Icon (string)

The url for an icon that can be used to represent the remote.

Homepage (string)

The url of a webpage describing the remote.

Filter (string)

The path of a local file to use to filter remote refs. See flatpak-remote-add(1) for details on the format of the file.

Note: This field is treated a bit special by flatpak remote-add. If you install a remote with --if-not-exists then and the remote is already configured, then the filter field of the remote configuration will be update anyway. And, if the filter field is *not* specified then any existing filters are cleared. The goal here is to allow a pre-configured filtered remote to be replaced with the regular one if you add the normal upstream (unfiltered) flatpakrepo file.

DeploySideloadCollectionID (string)

The collection ID of the remote, if it has one. This uniquely identifies the collection of apps in the remote, to allow peer to peer redistribution (see flatpak(1)). It is recommended to use this key over DeployCollectionID or CollectionID because only newer clients (Flatpak 1.12.8 or later) pay attention to it (and older clients don't handle collection IDs properly).

DeployCollectionID (string)

This is deprecated but still supported for backwards compatibility. Use DeploySideloadCollectionID instead.

CollectionID (string)

This is deprecated but still supported for backwards compatibility. Use DeploySideloadCollectionID instead.

Name

flatpak-installation — Configuration for an installation location

Description

flatpak can operate in system-wide or per-user mode. The system-wide data is located in $prefix/var/lib/flatpak/, and the per-user data is in $HOME/.local/share/flatpak/.

In addition to the default installation locations, more system-wide installations can be defined via configuration files /etc/flatpak/installations.d/, which must have the .conf extension and follow the format described below.

File format

The installation config file format is using the same .ini file format that is used for systemd unit files or application .desktop files.

[Installation …]

All the configuration for the the installation location with name NAME is contained in the [Installation "NAME"] group.

The following keys are recognized:

Path (string)

The path for this installation. This key is mandatory.

DisplayName (string)

The name to use when showing this installation in the UI.

Priority (integer)

A priority for this installation.

StorageType (string)

The type of storage used for this installation. Possible values include: network, mmc, sdcard, harddisk.

Examples

[Installation "extra"]
Path=/location/of/sdcard
DisplayName=Extra Installation
StorageType=sdcard

Name

flatpak-metadata — Information about an application or runtime

Description

Flatpak uses metadata files to describe applications and runtimes. The metadata file for a deployed application or runtime is placed in the toplevel deploy directory. For example, the metadata for the locally installed application org.gnome.Calculator is in ~/.local/share/flatpak/app/org.gnome.Calculator/current/active/metadata.

Most aspects of the metadata configuration can be overridden when launching applications, either temporarily via options of the flatpak run command, or permanently with the flatpak override command.

A metadata file describing the effective configuration is available inside the running sandbox at /.flatpak-info. For compatibility with older Flatpak versions, /run/user/$UID/flatpak-info is a symbolic link to the same file.

File format

The metadata file is using the same .ini file format that is used for systemd unit files or application .desktop files.

[Application] or [Runtime]

Metadata for applications starts with an [Application] group, metadata for runtimes with a [Runtime] group.

The following keys can be present in these groups:

name (string)

The name of the application or runtime. This key is mandatory.

runtime (string)

The fully qualified name of the runtime that is used by the application. This key is mandatory for applications.

sdk (string)

The fully qualified name of the sdk that matches the runtime. Available since 0.1.

command (string)

The command to run. Only relevant for applications. Available since 0.1.

required-flatpak (string list)

The required version of Flatpak to run this application or runtime. For applications, this was available since 0.8.0. For runtimes, this was available since 0.9.1, and backported to 0.8.3 for the 0.8.x branch.

Flatpak after version 1.4.3 and 1.2.5 support multiple versions here. This can be useful if you need to support features that are backported to a previous stable series. For example if you want to use a feature added in 1.6.0 that was also backported to 1.4.4 you would use 1.6.0;1.4.4;. Note that older versions of flatpak will just use the first element in the list, so make that the largest version.

tags (string list)

Tags to include in AppStream XML. Typical values in use on Flathub include beta, stable, proprietary and upstream-maintained. Available since 0.4.12.

[Context]

This group determines various system resources that may be shared with the application when it is run in a flatpak sandbox.

All keys in this group (and the group itself) are optional.

shared (list)

List of subsystems to share with the host system. Possible subsystems: network, ipc. Available since 0.3.

sockets (list)

List of well-known sockets to make available in the sandbox. Possible sockets: x11, wayland, fallback-x11, pulseaudio, session-bus, system-bus, ssh-auth, pcsc, cups. When making a socket available, flatpak also sets well-known environment variables like DISPLAY or DBUS_SYSTEM_BUS_ADDRESS to let the application find sockets that are not in a fixed location. Available since 0.3.

devices (list)

List of devices to make available in the sandbox. Possible values:

dri

Graphics direct rendering (/dev/dri). Available since 0.3.

input

Input devices (/dev/input).

kvm

Virtualization (/dev/kvm). Available since 0.6.12.

all

All device nodes in /dev, but not /dev/shm (which is separately specified). Available since 0.6.6.

shm

Access to the host /dev/shm (/dev/shm). Available since 1.6.1.

filesystems (list)

List of filesystem subsets to make available to the application. Possible values:

home

The entire home directory. Available since 0.3.

home/path

Alias for ~/path Available since 1.10. For better compatibility with older Flatpak versions, prefer to write this as ~/path.

host

The entire host file system, except for directories that are handled specially by Flatpak. In particular, this shares /home, /media, /opt, /run/media and /srv if they exist.

/dev is not shared: use devices=all; instead.

Parts of /sys are always shared. This option does not make additional files in /sys available.

Additionally, this keyword provides all of the same directories in /run/host as the host-os and host-etc keywords. If this keyword is used in conjunction with one of the host- keywords, whichever access level is higher (more permissive) will be used for the directories in /run/host: for example, host:rw;host-os:ro; is equivalent to host:rw;.

These other reserved directories are currently excluded: /app, /bin, /boot, /efi, /etc, /lib, /lib32, /lib64, /proc, /root, /run, /sbin, /tmp, /usr, /var.

Available since 0.3.

host-os

The host operating system's libraries, executables and static data from /usr and the related directories /bin, /lib, /lib32, /lib64, /sbin. Additionally, this keyword provides access to a subset of /etc that is associated with packaged libraries and executables, even if the host-etc keyword was not used: /etc/ld.so.cache, (used by the dynamic linker) and /etc/alternatives (on operating systems that use it, such as Debian).

To avoid conflicting with the Flatpak runtime, these are mounted in the sandbox at /run/host/usr, /run/host/etc/ld.so.cache and so on.

Available since 1.7.

host-etc

The host operating system's configuration from /etc.

To avoid conflicting with the Flatpak runtime, this is mounted in the sandbox at /run/host/etc.

Available since 1.7.

xdg-desktop, xdg-documents, xdg-download, xdg-music, xdg-pictures, xdg-public-share, xdg-videos, xdg-templates

freedesktop.org special directories. Available since 0.3.

xdg-desktop/path, xdg-documents/path, etc.

Subdirectories of freedesktop.org special directories. Available since 0.4.13.

xdg-cache, xdg-config, xdg-data

Directories defined by the freedesktop.org Base Directory Specification. Available since 0.6.14.

xdg-cache/path, xdg-config/path, xdg-data/path

Subdirectories of directories defined by the freedesktop.org Base Directory Specification. Available since 0.6.14.

xdg-run/path

Subdirectories of the XDG_RUNTIME_DIR defined by the freedesktop.org Base Directory Specification. Note that xdg-run on its own is not supported. Available since 0.4.13.

/path

An arbitrary absolute path. Available since 0.3.

~/path

An arbitrary path relative to the home directory. Available since 0.3.

~

The same as home. Available since 1.10. For better compatibility with older Flatpak versions, prefer to write this as home.

One of the above followed by :ro

Make the given directory available read-only.

One of the above followed by :rw

Make the given directory available read/write. This is the default.

One of the above followed by :create

Make the given directory available read/write, and create it if it does not already exist.

persistent (list)

List of homedir-relative paths to make available at the corresponding path in the per-application home directory, allowing the locations to be used for persistent data when the application does not have access to the real homedir. For instance making ".myapp" persistent would make "~/.myapp" in the sandbox a bind mount to "~/.var/app/org.my.App/.myapp", thus allowing an unmodified application to save data in the per-application location. Available since 0.3.

features (list)

List of features available or unavailable to the application, currently from the following list:

devel

Allow system calls used by development-oriented tools such as perf, strace and gdb. Available since 0.6.10.

multiarch

Allow running multilib/multiarch binaries, for example i386 binaries in an x86_64 environment. Available since 0.6.12.

bluetooth

Allow the application to use bluetooth (AF_BLUETOOTH) sockets. Note, for bluetooth to fully work you must also have network access. Available since 0.11.8.

canbus

Allow the application to use canbus (AF_CAN) sockets. Note, for this work you must also have network access. Available since 1.0.3.

per-app-dev-shm

Share a single instance of /dev/shm between all instances of this application run by the same user ID, including sub-sandboxes. If the application has the shm device permission in its devices list, then this feature flag is ignored. Available since 1.12.0.

A feature can be prefixed with ! to indicate the absence of that feature, for example !devel if development and debugging are not allowed.

unset-environment (list)

A list of names of environment variables to unset. Note that environment variables to set to a value (possibly empty) appear in the [Environment] group instead.

[Instance]

This group only appears in /.flatpak-info for a running app, and not in the metadata files written by application authors. It is filled in by Flatpak itself.

instance-id (string)

The ID of the running instance. This number is used as the name of the directory in XDG_RUNTIME_DIR/.flatpak where Flatpak stores information about this instance.

instance-path (string)

The absolute path on the host system of the app's persistent storage area in $HOME/.var.

app-path (string)

The absolute path on the host system of the app's app files, as mounted at /app inside the container. Available since 0.6.10.

Since 1.12.0, if flatpak run was run with the --app-path option, this key gives the absolute path of whatever files were mounted on /app, even if that differs from the app's normal app files.

If flatpak run was run with --app-path= (resulting in an empty directory being mounted on /app), the value is set to the empty string.

original-app-path (string)

If flatpak run was run with the --app-path option, this key gives the absolute path of the app's original files, as mounted at /run/parent/app inside the container. Available since 1.12.0.

If this key is missing, the app files are given by app-path.

app-commit (string)

The commit ID of the application that is running. The filename of a deployment of this commit can be found in original-app-path if present, or app-path otherwise.

app-extensions (list of strings)

A list of app extensions that are mounted into the running instance. The format for each list item is EXTENSION_ID=COMMIT. If original-app-path is present, the extensions are mounted below /run/parent/app; otherwise, they are mounted below /app.

branch (string)

The branch of the app, for example stable. Available since 0.6.10.

arch (string)

The architecture of the running instance.

flatpak-version (string)

The version number of the Flatpak version that ran this app. Available since 0.6.11.

runtime-path (string)

The absolute path on the host system of the app's runtime files, as mounted at /usr inside the container. Available since 0.6.10.

Since 1.12.0, if flatpak run was run with the --usr-path option, this key gives the absolute path of whatever files were mounted on /usr, even if that differs from the app's normal runtime files.

original-runtime-path (string)

If flatpak run was run with the --runtime-path option, this key gives the absolute path of the app's original runtime, as mounted at /run/parent/usr inside the container. Available since 1.12.0.

If this key is missing, the runtime files are given by runtime-path.

runtime-commit (string)

The commit ID of the runtime that is used. The filename of a deployment of this commit can be found in original-runtime-path if present, or runtime-path otherwise.

runtime-extensions (list of strings)

A list of runtime extensions that are mounted into the running instance. The format for each list item is EXTENSION_ID=COMMIT. If original-app-path is present, the extensions are mounted below /run/parent/usr; otherwise, they are mounted below /usr.

extra-args (string)

Extra arguments that were passed to flatpak run.

sandbox (boolean)

Whether the --sandbox option was passed to flatpak run.

build (boolean)

Whether this instance was created by flatpak build.

session-bus-proxy (boolean)

True if this app cannot access the D-Bus session bus directly (either it goes via a proxy, or it cannot access the session bus at all). Available since 0.8.0.

system-bus-proxy (boolean)

True if this app cannot access the D-Bus system bus directly (either it goes via a proxy, or it cannot access the system bus at all). Available since 0.8.0.

[Session Bus Policy]

If the sockets key is not allowing full access to the D-Bus session bus, then flatpak provides filtered access.

The default policy for the session bus only allows the application to own its own application ID, its subnames and its own application id as a subname of "org.mpris.MediaPlayer2". For instance if the app is called "org.my.App", it can only own "org.my.App", "org.my.App.*" and "org.mpris.MediaPlayer2.org.my.App". It is only allowed to talk to names matching those patterns, plus the bus itself (org.freedesktop.DBus) and the portal APIs (bus names of the form org.freedesktop.portal.*).

Additionally the app is always allowed to reply to messages sent to it, and emit broadcast signals (but these will not reach other sandboxed apps unless they are allowed to talk to your app.

If the [Session Bus Policy] group is present, it provides policy for session bus access.

Each key in this group has the form of a D-Bus bus name or prefix thereof, for example org.gnome.SessionManager or org.freedesktop.portal.*

The possible values for entry are, in increasing order or access:

none

The bus name or names in question is invisible to the application. Available since 0.2.

see

The bus name or names can be enumerated by the application. Available since 0.2.

talk

The application can send messages/ and receive replies and signals from the bus name or names. Available since 0.2.

own

The application can own the bus name or names (as well as all the above). Available since 0.2.

[System Bus Policy]

If the sockets key is not allowing full access to the D-Bus system bus, then flatpak does not make the system bus available unless the [System Bus Policy] group is present and provides a policy for filtered access. Available since 0.2.

Entries in this group have the same form as for the [Session Bus Policy] group. However, the app has no permissions by default.

[Environment]

The [Environment] group specifies environment variables to set when running the application. Available since 0.3.

Entries in this group have the form VAR=VALUE where VAR is the name of an environment variable to set.

Note that environment variables can also be unset (removed from the environment) by listing them in the unset-environment entry of the [Context] group.

[Extension NAME]

Runtimes and applications can define extension points, which allow optional, additional runtimes to be mounted at a specified location inside the sandbox when they are present on the system. Typical uses for extension points include translations for applications, or debuginfo for sdks. The name of the extension point is specified as part of the group heading. Since 0.11.4, the name may optionally include a tag in the NAME in the name@tag ref syntax if you wish to use different configurations (eg, versions) of the same extension concurrently. The "tag" is effectively ignored, but is necessary in order to allow the same extension name to be specified more than once.

directory (string)

The relative path at which the extension will be mounted in the sandbox. If the extension point is for an application, the path is relative to /app, otherwise it is relative to /usr. This key is mandatory. Available since 0.1.

version (string)

The branch to use when looking for the extension. If this is not specified, it defaults to the branch of the application or runtime that the extension point is for. Available since 0.4.1.

versions (string)

The branches to use when looking for the extension. If this is not specified, it defaults to the branch of the application or runtime that the extension point is for. Available since 0.9.1, and backported to the 0.8.x branch in 0.8.4.

add-ld-path (string)

A path relative to the extension point directory that will be appended to LD_LIBRARY_PATH. Available since 0.9.1, and backported to the 0.8.x branch in 0.8.3.

merge-dirs (string)

A list of relative paths of directories below the extension point directory that will be merged. Available since 0.9.1, and backported to the 0.8.x branch in 0.8.3.

download-if (string)

A condition that must be true for the extension to be auto-downloaded. As of 1.1.1 this supports multiple conditions separated by semi-colons.

These are the supported conditions:

active-gl-driver
active-gtk-theme
have-intel-gpu
have-kernel-module-*
on-xdg-desktop-*
autoprune-unless (string)

A condition that must be false for the extension to be considered unused when pruning. For example, flatpak uninstall --unused uses this information. The only currently recognized value is active-gl-driver, which is true if the name of the active GL driver matches the extension point basename. Available since 0.11.8.

enable-if (string)

A condition that must be true for the extension to be enabled. As of 1.1.1 this supports multiple conditions separated by semi-colons. See download-if for available conditions.

subdirectory-suffix (string)

A suffix that gets appended to the directory name. This is very useful when the extension point naming scheme is "reversed". For example, an extension point for GTK+ themes would be /usr/share/themes/$NAME/gtk-3.0, which could be achieved using subdirectory-suffix=gtk-3.0. Available since 0.9.1, and backported to the 0.8.x branch in 0.8.3.

subdirectories (boolean)

If this key is set to true, then flatpak will look for extensions whose name is a prefix of the extension point name, and mount them at the corresponding name below the subdirectory. Available since 0.1.

no-autodownload (boolean)

Whether to automatically download extensions matching this extension point when updating or installing a 'related' application or runtime. Available since 0.6.7.

locale-subset (boolean)

If set, then the extensions are partially downloaded by default, based on the currently configured locales. This means that the extension contents should be a set of directories with the language code as name. Available since 0.9.13 (and 0.6.6 for any extensions called *.Locale)

autodelete (boolean)

Whether to automatically delete extensions matching this extension point when deleting a 'related' application or runtime. Available since 0.6.7.

collection-id (string)

The ID of the collection that this extension point belongs to. If this is unspecified, it defaults to the collection ID of the application or runtime that the extension point is for. Currently, extension points must be in the same collection as the application or runtime that they are for. Available since 0.99.1.

[ExtensionOf]

This optional group may be present if the runtime is an extension.

ref (string)

The ref of the runtime or application that this extension belongs to. Available since 0.9.1.

runtime (string)

The runtime this extension will be inside of. If it is an app extension, this is the app's runtime; otherwise, this is identical to ref, without the runtime/ prefix. Available since 1.5.0.

priority (integer)

The priority to give this extension when looking for the best match. Default is 0. Available since 0.9.1, and backported to the 0.8.x branch in 0.8.3.

tag (string)

The tag name to use when searching for this extension's mount point in the parent flatpak. Available since 0.11.4.

[Extra Data]

This optional group may be present if the runtime or application uses extra data that gets downloaded separately. The data in this group gets merged into the repository summary, with the xa.extra-data-sources key.

If multiple extra data sources are present, their uri, size and checksum keys are grouped together by using the same suffix. If only one extra data source is present, the suffix can be omitted.

NoRuntime (boolean)

Whether to mount the runtime while running the /app/bin/apply_extra script. Defaults to true, i.e. not mounting the runtime. Available since 0.9.1, and backported to the 0.8.x branch in 0.8.4.

uriX (string)

The uri for extra data source X. The only supported uri schemes are http and https. Available since 0.6.13.

sizeX (integer)

The size for extra data source X. Available since 0.6.13.

checksumX (string)

The sha256 sum for extra data source X. Available since 0.6.13.

[Policy SUBSYSTEM]

Subsystems can define their own policies to be placed in a group whose name has this form. Their values are treated as lists, in which items can have their meaning negated by prepending ! to the value. They are not otherwise parsed by Flatpak. Available since 0.6.13.

Name

flatpak-remote — Configuration for a remote

Description

Flatpak stores information about configured remotes for an installation location in $installation/repo/config. For example, the remotes for the default system-wide installation are in $prefix/var/lib/flatpak/repo/config, and the remotes for the per-user installation are in $HOME/.local/share/flatpak/repo/config.

Normally, it is not necessary to edit remote config files directly, the flatpak remote-modify command should be used to change properties of remotes.

System-wide remotes can be statically preconfigured by dropping flatpakref files into /etc/flatpak/remotes.d/.

File format

The remote config file format is using the same .ini file format that is used for systemd unit files or application .desktop files.

[remote …]

All the configuration for the the remote with name NAME is contained in the [remote "NAME"] group.

The following keys are recognized by OSTree, among others:

url (string)

The url for the remote. An URL of the form oci+https:// or oci+http:// is a Flatpak extension that indicates that the remote is not an ostree repository, but is rather an URL to an index of OCI images that are stored within a container image registry.

gpg-verify (boolean)

Whether to use GPG verification for content from this remote.

gpg-verify-summary (boolean)

Whether to use GPG verification for the summary of this remote.

This is ignored if collection-id is set, as refs are verified in commit metadata in that case. Enabling gpg-verify-summary would break peer to peer distribution of refs.

collection-id (string)

The globally unique identifier for the upstream collection repository, to allow mirrors to be grouped.

All flatpak-specific keys have a xa. prefix:

xa.disable (boolean)

Whether the remote is disabled. Defaults to false.

xa.prio (integer)

The priority for the remote. This is used when listing remotes, and when searching them for the runtime needed by an app. The remote providing the app is searched for its runtime before others with equal priority. Defaults to 1.

xa.noenumerate (boolean)

Whether this remote should be ignored when presenting available apps/runtimes, or when searching for a runtime dependency. Defaults to false.

xa.nodeps (boolean)

Whether this remote should be excluded when searching for dependencies. Defaults to false.

xa.title (string)

An optional title to use when presenting this remote in a UI.

xa.title-is-set (boolean)

This key is set to true if xa.title has been explicitly set.

xa.comment (string)

An optional single-line comment to use when presenting this remote in a UI.

xa.comment-is-set (boolean)

This key is set to true if xa.comment has been explicitly set.

xa.description (string)

An optional full-paragraph of text to use when presenting this remote in a UI.

xa.description-is-set (boolean)

This key is set to true if xa.description has been explicitly set.

xa.homepage (string)

An optional URL that points to a website for this repository to use when presenting this remote in a UI.

xa.homepage-is-set (boolean)

This key is set to true if xa.homepage has been explicitly set.

xa.icon (string)

An optional URL that points to an icon for this repository to use when presenting this remote in a UI.

xa.icon-is-set (boolean)

This key is set to true if xa.icon has been explicitly set.

xa.default-branch (string)

The default branch to use when installing from this remote.

xa.default-branch-is-set (boolean)

This key is set to true if xa.default-branch has been explicitly set.

xa.main-ref (string)

The main reference served by this remote. This is used for origin remotes of applications installed via a flatpakref file.
