PPAs are 3rd party sources (*PPA = Personal Package Archive*) so all security is on you to perform as no guarantees of quality/fitness etc. is provided. A quick check of https://launchpad.net/~flatpak/+archive/ubuntu/stable should have shown you it didn't provide support for *kinetic* (22.10), thus adding it was an incorrect/unwise decision.

The *duplicate* answer deals with your error message & mistake in adding the PPA; the excellent answer from @Archisman Panigrahi outlines both how to fix for your situation & what you should have done.

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

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
