Unbuntu is still missing.

I'd go with feature-request and discussion, this way it clearly invites to talk about changing Comunity's behaviour for that matter. Of course link to this question so that people can read what's already been said!

Very good point! This problem makes for a new meta question on its own, this way we could make it a feature request. Do you mind adding it as one?

An answer starting with “It worked thx” is probably a comment and not an answer.

Btw this question of you on U&L has the exact same problems and also got downvoted because of that – and not by me, rest assured.

I was the one that downvoted the question you cite. I did this because you neither describe your situation nor asked a clear question, but merely added not even cleaned (I then did that for you) terminal output with lots of unneeded information. The full output of lsb_release -a for example is fine, but it's unclear what you want to say with it. If that's just “I use 17.10.” then why don't you just write this instead of forcing potential answerers to dig through this pile of terminal output and merely guess what exactly you did and want?

For every question that gets downvoted, check every single section of askubuntu.com/help/how-to-ask and ask yourself to what extent your question answers to it.

Maybe you just got bad luck: At first your answer wasn't that great, so somebody thought it would be worth a downvote. Later there were other answers that simply were better (Gilles just is a real pro IMO), so your answer got to the bottom of the page where next to nobody gets to. My advice for the next time: Write your answer as god as you can so that nobody has a reason to downvote it at any time.

@terdon No doubt we do want the history tag, but do we also want a bash-history tag?
