Install the Software Flatpak plugin
If you are running GNOME, it is also a good idea to install the Flatpak plugin for GNOME Software. To do this, run:apt install gnome-software-plugin-flatpak
Add the Flathub repository
Flathub is the best place to get Flatpak apps. To enable it, run:flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
To complete setup, restart your system. Now all you have to do is install some apps!
