Install Flatpak

To install Flatpak on Ubuntu 18.10 (Cosmic Cuttlefish) or later, open the Terminal app and run: <terminal-command>sudo apt install flatpak</terminal-command> For older versions up to Ubuntu 18.04 LTS (Bionic Beaver), the official Flatpak PPA is required to install Flatpak and keep it up to date.

The GNOME Software plugin makes it possible to install apps without needing the command line. To install, run: <terminal-command>sudo apt install gnome-software-plugin-flatpak</terminal-command> Note: Ubuntu distributes GNOME Software as a Snap in versions 20.04 to 23.04, and replaced it with App Center in 23.10 and newer—neither of which support installing Flatpak apps. Installing the Flatpak plugin will also install a deb version of GNOME Software, resulting in two "Software" apps being installed at the same time on Ubuntu 20.04 to 23.04, and a single new \"Software\" app on Ubuntu 23.10 and newer.
