I've seen this more than once. A question with a very weird dependency issue, got an answer to it's specific problem, and later on (sometimes months), someone votes to close it against the super general and unhelpful "https://askubuntu.com/q/140246/169736". This wastes reviewers time and close votes that should be used against other close reasons. If two questions whose answers can't be merged, is very likely they are not duplicates.

I know people know that I hate that Q with all my soul (along with others mega questions), and I will offer 5 questions about how to check dependencies issues in a way that any reader is capable to help himself instead of using carpet bombing.
