    You have multiple issues; your missing installation media is enabled but can't be found, plus you've added 3rd party personal package archive (PPAs) that don't provide support for jammy or 22.04... Being 3rd party sources, checking they support your OS/release is on you to do. These need to be removed/disabled. – guiverc Feb 26 '23 at 12:59
