I need a distro that is stable with a particular need to set up zero input automatic updates. If an update asks for a password or needs user interaction in basically any way it simply won’t get done. All he needs is a reliable platform for browsing the web. I am replacing an Ubuntu system that has apparently just stopped working (I have not had a chance to examine it yet) after years and years of not getting proper updates after he forgot his password.
Something like Bazzite is intriguing because of it’s locked down environment although he is very much not a gamer. Is there something locked down like Bazzite but with long term LTS release cycle?
You could try Aurora, it’s made by the same people as Bazzite but with a general (or developer) focus instead of a gamer focus, and while it’s not LTS I think it updates less rapidly than Bazzite.
If your user is really tech un-savvy though, I’d just go with ChromeOS Flex. For all their (many) faults Google do at least produce a simple all-in-one experience, and I’d rather my elderly relative use Chrome’s password manager than no password manager at all.
