this never happened before, it’s also not happening ion my backup computer (same OS, xubuntu 24.04).
Message: get more security updates through ubuntu pro with esm-apps enabled, learn more about ubuntu pro <url here>
How do I get rid of it.
Ubuntu never advertised itself so blatantly.
There is literally not a single useful comment here.
You have packages from outside the official main repo, in the universe repo.
You are using a stable Distribution so packages are frozen and need backported security updates.
You dont get them for the optional universe repos, but if you give them a bit of money (or afaik Ubuntu pro is even free for a few devices) then they will also support these 3rd party packages.
It is an optional service, they warn you that you use outdated packages, and offer a solution.
I dont use Ubuntu and Snaps are crap, but this is totally fine.
