When Can I enable bash-completion for the new apt command? was first posted, 14.04 LTS was new and was the only Ubuntu release for which the issue applied. It seems to me that the question was, at that time, about as version-specific as questions can get.

Since then, 14.10 and 15.04 have been released, and they both suffer from the same problem. (I have verified this.) This is to say that they both ship with the apt utility but neither ships with bash-completion for it. There's no reason to think Oli's solution is any any way release-specific (just the problem, as it originally existed). Furthermore, I have tested his solution on 15.04 and it works.

So I've removed the 14.04 tag, in accordance with Oli's advice about how to use version tags:

###How do you ever know something is version specific?

Do your best. If you suspect it to be version specific, add the tag. If you can show it's not, remove it. Don't shoot on sight.

While I've expressed my views on the controversy in this post, this is primarily as a form of full disclosure. I didn't remove the tag to make a statement or advance any policy position. Instead:

1. The tag was confusing for me when I found the question when searching for help with my 15.04 problem.
2. I followed the link to this meta question and was reminded of its history (which I'd mostly forgotten about).
3. I verified that both the question and answer now apply to multiple releases.
4. So I removed the tag.

I would not ordinarily post a meta answer when retagging a question, obviously. In this case there's been spirited disagreement and I want to make clear that I am not trying to act in a way that's unaccountable to the community. If someone puts the tag back, I will not get an in edit war to remove it again. (I don't see any reason to put it back, though, from any of the perspectives that have been expressed here. So my guess is, that won't happen.)

I have anticipated two possible concerns:

• Why not add tags instead? I don't think anyone wants questions that apply to three releases to have version tags, but even if we did generally do that, we couldn't here. A question can only have five tags; apt, bash, and autocompletion remain important to the question; and thus it cannot reasonably be tagged with 14.04, 14.10, and 15.04 too.
• But, for the OP (Oli), wasn't it about 14.04? Originally, yes, but now it affects all recent releases and questions on Ask Ubuntu don't exist only (or even primarily) for their askers. The task of our site and community is to create a library of Ubuntu questions and answers, which can then be used by anyone. At this point in time, removing the tag doesn't harm the author, but it does help the community at large, now and in the future.
