default-flatpaks Module for Startingpoint

The default-flatpaks module can be used to install flatpaks from a configurable remote on first boot. This module first removes the Fedora Flatpaks remote and Flatpaks that come pre-installed in Fedora. A Flatpak remote is configured the first time the module is used, but it can be re-configured in subsequent usages of the module. If no Flatpak remote is specified, the module will default to using Flathub.

Flatpaks can either be installed system-wide or per-user, though per-user flatpaks will be installed for every user on a system. Previously-installed flatpaks can also be removed.

The module uses the following scripts to handle flatpak setup:

  • /usr/bin/system-flatpak-setup
  • /usr/bin/user-flatpak-setup

The scripts are run on first boot and login by these services:

  • /usr/lib/systemd/system/system-flatpak-setup.service
  • /usr/lib/systemd/user/user-flatpak-setup-service

system-flatpak-setup checks the flatpak repo information and install/remove lists created by the module. It also checks for the existence of /etc/ublue-os/system-flatpak-configured before running. user-flatpak-setup functions the same for user flatpaks, but checks for $HOME/.config/ublue-os/user-flatpak-configured instead.

Flatpak setup can be run again by removing /etc/ublue-os/system-flatpak-configured for system-wide flatpaks, or $HOME/.config/ublue-os/user-flatpak-configured for user flatpaks.

This module stores the Flatpak remote configuration and Flatpak install/remove lists in /etc/flatpak/. There are two subdirectories, user and system corresponding with the install level of the Flatpaks and repositories. Each directory has text files containing the IDs of flatpaks to install and remove, plus a repo-info.yml containing the details of the Flatpak repository.

Example configurations

type: default-flatpaks
system:
  # If no repo information is specified, Flathub will be used by default
  repo-url: https://dl.flathub.org/repo/flathub.flatpakrepo
  repo-name: flathub
  repo-title: "Flathub (system-wide)" # Optional; this sets the remote's user-facing name in graphical frontends like GNOME Software
  install:
    - org.gnome.Loupe
  remove:
    - org.gnome.eog
# A flatpak repo can also be added without having to install flatpaks,
# as long as one of the repo- fields is present
user:
  repo-name: flathub

# Assuming that the above example is called first in a recipe,
# a subsequent usage might look like this:
type: default-flatpaks
system:
  # If the repo-* fields are omitted, the configured repo will
  # use the previous configuration. Otherwise, it defaults to Flathub.
  install:
    - org.kde.kdenlive
user:
  # repo-name will overwrite the previously-configured repo-name for the user remote
  repo-name: flathub-user
  repo-title: "Flathub (User)
