You don't need a PPA to install Flatpak in Ubuntu 22.10, because it is already there in the default repositories. You got this error message because the PPA does not have a package for your version of Ubuntu.

First, remove the PPA.

sudo add-apt-repository --remove ppa:flatpak/stable

Then, update the APT index.

sudo apt update

Finally, install flatpak with

sudo apt install flatpak
