This is exactly answered by the linked duplicate - https://askubuntu.com/questions/866901/what-can-i-do-if-a-repository-ppa-does-not-have-a-release-file - basically Jammy is still in development so MOST PPAs will not have release files for Jammy. Also, **Jammy is offtopic** as it's currently in development.

your only solution is to remove the PPA entries. Jammy is still in development, and you can't 'fix' a PPA that doesn't have a release file for a release that has only been in development for 2 weeks so far.

Refer https://askubuntu.com/help/on-topic where you'll notice only supported releases of Ubuntu and flavors are on-topic for this site. For *jammy* jellyfish [22.04] questions you'll need to use a development support site such as IRC (#ubuntu-next) or Ubuntu Forums, or wait until after release for this site [expected release date for Ubuntu 22.04 is 21 April 2022](https://discourse.ubuntu.com/t/jammy-jellyfish-release-schedule/23906)) when your question will be on-topic here.

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.
