Install GNOME Software (Optional)
Ubuntu switched to a snap-packaged Software Store since Ubuntu 20.04 LTS. While this step has many benefits, there is also one drawback: The snap version doesn't support Flatpak packages. If you wish to install Flatpak packages from a software store application, you need to install the original GNOME Software application.

Restart your computer
It is necessary to restart your computer to add Flatpak paths alongside the system ones. Otherwise, you may see strange errors. Unfortunately, just logging out and logging in is not enough.
