I've seen a few answers which are essentially saying "install a different Linux distro, and you won't have this problem". Even if the answerer is acting in good faith, trying to be helpful, but the technical fix is to switch distros, is this acceptable?
Based on How should answers which basically equate to "give up and use x instead" be handled?, I am inclined to think that answers suggesting using a different OS aren't real answers. Should I flag them as non-answers, not welcome, or maybe just downvote them?
An interesting recent example of this is here: How do I install Alientvault SIEM manually? . Not the epitome of the type of answer, but I'm inclined to think it should have been a comment.
My suspicion is that this is probably best dealt with on a case by case basis. The questions I was thinking most of were where someone is using Ubuntu and having a problem that looks soluble within Ubuntu. If I'm asking specifically for Ubuntu help (not 'how do I get my scanner to work in Linux', e.g.), and you want me to stop using it ("use NetBSD, it works there!"), you're kind of working in a parallel reality. I mean, that kind of thing can make a good comment or data point, but not so much an answer.
Note : I originally had a link to a pretty non-germane example answer, so I've edited to remove it.
