Flatpak

This material is work-in-progress ... More documentation and testing is needed, but everything currently here should be safe to follow. (Last edited by User4708 on 3 Jan 2023.)

Flatpak is a technology for building and distributing applications with the goal of having a universal package format for all Linux distributons, it is similar to Snap,

Setup / Installation

From: https://flatpak.org/setup/Alpine/

Note: To install Flatpak you will need to enable the Community repository, See: Repositories - Managing repositories

To install Flatpak run:

# apk add flatpak

It's recommended to run flatpak as your user, rather than as root. Therefore, add your user to the flatpak group:

# adduser <YourUsername> flatpak

Next you need to add a repository, for this guide we will use the recommended repository, Flathub.

flatpak remote-add --user --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

Now reboot to complete setup

Note: graphical installation of Flatpak apps may not be possible with Alpine.

Usage

To get all of the available options to use with the flatpak command run: flatpak --help or flatpak -h,

Search

To search for applications run flatpak search <appplicationname>

Example:

Contents of flatpak search chromium

Troubleshooting

Permission errors

If you receive errors about permissions then you may need to add your user to the flatpak group, See step two of Setup / Installation.

Note: You may need to log out and log back in or reboot for the group change(s) to take effect

Fixing audio issues

If you have a minimal setup and don't have access to audio devices you will need to set the XDG_RUNTIME_DIR variable. Save the following script in /etc/profile.d/xdg_runtime_dir.sh and re-login to have it set up properly.

if test -z "${XDG_RUNTIME_DIR}"; then
  export XDG_RUNTIME_DIR=/tmp/$(id -u)
fi

When you launch a Flatpak you will need to start pulseaudio as well:

pulseaudio --start && flatpak run com.example.Example
