That even though you are running an LTS version of Ubuntu (e.g. Ubuntu 22.04), some packages that have arrived over a year ago on e.g. 23.10 will never arrive on 22.04.
This is mine. This is fine for my server, where I want it to be mega stable and always up. I can always add other repos for the few packages that I need to be up to date for whatever reason (podman for me recently). But my daily driver needs quicker updates than that.
