A question was asked about a problem that was later discovered to be nonexistent. The problem was due to a typo and the poster only realized this after asking the question.

Should I vote to close a question like this? If so, which reason should I use? The choices are:

• exact duplicate
  This question covers exactly the same ground as earlier questions on this topic; its answers may be merged with another identical question.
• off topic
  Questions on Ubuntu are expected to generally relate to ubuntu and developers for ubuntu, within the scope defined in the faq.
• subjective and argumentative
  It's impossible to objectively answer this question; questions of this type are too open ended and usually lead to confrontation and argument.
• not a real question
  It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, or rhetorical and cannot be reasonably answered in its current form.
• too localized
  This question would only be relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet.
• belongs on meta
  This question is a discussion of this web site or community itself, and is a better fit for Meta.
