For a simple home server running a couple docker containers over the internet, is it a big security risk to keep using 22.04 LTS until support for it ends (with Ubuntu pro this means until 2032)? A lot of home server admins online seem to recommend this because the upgrade process can cause issues.
The problem with frozen distros isn’t that they have unreliable support, but that security fixes that aren’t CVEs are out-of-scope. So I don’t think 22.04 LTS is too much worse than 24.04 LTS in that regard (not that either is great, of course).
You should be fine, especially since your services are containerized, so the containers themselves likely matter more. I wouldn’t stress it until 2032, because your base OS would have pretty old software by then, including the kernel which still matters for most container runtimes, but skipping one version should be fine.
