Chrome OS

    Flatpak applications can be installed on ChromeOS with the Crostini Linux compatibility layer. This is not available for all ChromeOS devices, so you should ensure your device is compatible before proceeding. A list of compatible devices is maintained here.

  1. Enable Linux support

    Navigate to chrome://os-settings, and scroll down to Developers and turn on Linux development environment. ChromeOS will take some time downloading and installing Linux.

  2. Start a Linux terminal

    Press the Search/Launcher key, type "Terminal", and launch the Terminal app.

  3. Install Flatpak

    To install Flatpak, run the following in the terminal:

    sudo apt install flatpak

    A more up to date flatpak package is available in the Debian backports repository.

  4. Add the Flathub repository

    Flathub is the best place to get Flatpak apps. To enable it, run:

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

    To complete setup, restart Linux. You can do this by right-clicking terminal, and then clicking "Shut down Linux". Now all you have to do is install some apps!
