FLATPAK PREINSTALL(1) flatpak preinstall FLATPAK PREINSTALL(1)
flatpak-preinstall - Install flatpaks that are part of the
operating system
flatpak preinstall [OPTION...]
This command manages flatpaks that are part of the operating
system. If no options are given, running flatpak preinstall will
synchronize (install and remove) flatpaks to match the set that
the OS vendor has chosen.
Preinstalled flatpaks are defined by dropping .preinstall files
into the directories /usr/share/flatpak/preinstall.d/ and
/etc/flatpak/preinstall.d/. The OS runs flatpak preinstall -y (or
its GUI equivalent) on system startup, which then does the actual
installation.
This system allows the OS vendor to define the list of flatpaks
that are installed together with the OS, and also makes it
possible for the OS vendor to make changes to the list in the
future, which is then applied once flatpak preinstall is run next
time. Users can opt out of preinstalled flatpaks by simply
uninstalling them, at which point they won't get automatically
reinstalled again.
The .preinstall file is using the same .ini file format that is
used for systemd unit files or application .desktop files.
[Flatpak Preinstall NAME]
The NAME is the fully qualified name of the runtime or
application. All the information for a single runtime or
application is contained in one [Flatpak Preinstall NAME] group.
Multiple groups can be defined in a single file.
The following keys can be present in this group:
Install (boolean)
Whether this group should be installed. If this key is not
specified, the group will be installed.
Branch (string)
The name of the branch from which to install the application
or runtime. If this key is not specified, the "master" branch
is used.
IsRuntime (boolean)
Whether this group refers to a runtime. If this key is not
specified, the group is assumed to refer to an application.
CollectionID (string)
The collection ID of the remote to use, if it has one.
[Flatpak Preinstall org.gnome.Loupe]
Branch=stable
IsRuntime=false
The following options are understood:
-h, --help
Show help options and exit.
--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.
--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.
--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.
