Install Flatpak(s) in Vanilla OS
Learn how to install Flatpak packages in Vanilla OS.
Flatpak is a universal package format for Linux desktop applications. It works on most Linux distributions, Vanilla OS included. Flatpak applications get distributed as bundles, similar to native packages, but they are sandboxed and can be updated independently from the host system.
The preferred way to install Flatpak is to toggle it in the First Setup wizard. If you didn’t toggle it, you can install it manually using the transactional shell:
sudo abroot exec apt install flatpak gnome-software-plugin-flatpak
Reboot once the installation is complete.
Alternatively, you can install Flatpak inside a managed container using
apx install flatpak
In this case, you will always need to run Flatpak commands inside the
apx run flatpak install flathub org.gnome.gedit
Flatpak needs to know where to look for applications. The default and most popular repository for installing Flatpaks is Flathub, which you can add using the following command:
flatpak remote-add --if-not-exists --user flathub https://flathub.org/repo/flathub.flatpakrepo
--user flag, which tells Flatpak to install applications only for the current user, is needed because the root partitions in Vanilla OS are small-sized and must get updated in a transactional way only.
