flatpak-flatpakref: Reference to a remote for an application or runtime


flatpak-flatpakref - Reference to a remote for an application or runtime


Flatpak uses flatpakref files to share information about a remote for a single application. The flatpakref file contains enough information to add the remote and install the application. Use the flatpak install --from command to do so.

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

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

A flatpakref file can also refer to a remote for a runtime.


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

The name of the branch from which to install the application or runtime. If this key is not specified, the "master" branch is used.
