As developing a decent QA process for Linux distros seems to be impossible I don't get how enabling automatic updates by default seemed like a reasonable thing to do...

@buherator I think this is generally why the advice is that you shouldn’t actually have auto-updates turned on, by default the auto-update systems only apply security patches even if you enable them usually too

@froge In theory maybe, in practice these updates introduce breaking changes (see my mention of QA).
