This is done. Attempting to use this tag - or edit any post that currently uses it - will result in the following error:
Which also links to this discussion: Should we split the installation tag into seperate tags for the installation of Ubuntu and the installation of software?
Y'all might want to add further guidance there.
We also have various windows tags as well as e.g. macosx, kali or debian although we do not support questions that are specific to those foreign operating systems.
Their main purpose are dual-boot questions where there are issues having both Ubuntu or one of its official flavours installed together, but other common use cases include questions about ...
Yes, the tag should be blacklisted.
I cannot see any useful use of the tag, so I propose that:
Community members go through the tag page and replace tags on posts with more useful and descriptive tags.
The help tag is blacklisted so it cannot be used.
While help can refer to documentation, yelp is better.
The help tag was blacklisted on ...
because someone with enough reputation created it and then none have been bothered to do anything about it. A lot of new users will probably use this misleading tag.
a lot of the questions on the site are errors, but adding that they are errors isn't helpful.
The error tag has gotten to the point where mods should probably ask SE employees to blacklist it.
That's how tag blacklisting is achieved.
This tag seems to come back slowly--a couple posts here and there. But I can't deny it keeps coming back. Furthermore, it doesn't seem like discussion of it on meta has kept it from returning. It might even be coming ...
This tag is far too tenacious. The links seen on thing page point to its recurring attack, and it is just too general. However, I fear that blacklisting it could open tags like error-handling up to misuse for general errors, not specifically error handlers. In fact, it already is being a little mishandled(no bad pun intended) in this way.
Wubi was only "discontinued" by a very strange sense of that term, as it continues shipping on official Ubuntu ISOs and working.
Furthermore, even if we were to consider Wubi unsupported starting with 13.04, Ubuntu 12.04 LTS remains supported and won't be end-of-life for about 2.5 more years.
Now for the details...
Some background information on ...
IMHO it's a useless tag.
We should burn it in favor of the more specific tags 12.04, 14.04, etc. I have to agree with @NathanOsman when he says "I can't think of a legitimate reason for using this tag that wouldn't be covered by something more specific."
We don't want or need a post tag.
The term is clearly ambiguous and in my opinion unlikely to be a favourite. As it seems to me that tags are used to locate questions within ones area of expertise and there doesn't appear to be a common thread linking any of the questions utilizing the word post or any of it's derivatives I think that tag and ...
I think that the confusion exist because the "post" tag does not have meaning or the possible meanings are misleading : are we talking about the act "to post" or the content ?
If we are talking about the act, a tag "posting" should be better and yes the question you mentioned fits in. It can be helpful to have a tag like this one.
If we are talking about ...
Things to consider when discussing this:
grub-error is generally a more serious error - however, while that needs to be taken into consideration, its not really a stopping problem.
Currently, for the moment I have it as a synonym of grub. However, because I didn't merge the tags, we can easily change that to whatever we want, if we need to.
