Q:

As a new user without much rep, what should I do if someone else has already asked a question I have, but it has no answers?

Suppose you had a question, and you really want a good answer that would solve your problem, but noticed it was already asked by someone else. However, no one has posted any answers. The question is technically considered "unanswered", but a lot of users who would otherwise bother to give a correct answer probably skip the question completely for some reason.
What should I do in this case?
One idea is to ask a new, completely identical question, in the hope users will notice the new question and post an answer there. But would that go against SE policy?

Note: This is adapted from If you are not satisfied with answers on someone else's question, should you ask your own?, but that doesn't cover the case where the original question is unanswered. Also, it is not a duplicate of How do I get attention for one of my own questions without a good answer?, as that question asks about getting attention for one's own questions, while this one and the one linked above ask about getting an answer if someone else has already posted the same thing.

A:

Common wisdom has been, if it is identical - put a bounty on it, and/or make substantial improvements to it. Of course, this needs reputation, and if you're a new user who doesn't have much rep, you need other approaches. Begging for someone to bounty it is a terrible idea. Following up if someone offers to bounty is a good one - this happens sometimes. 
If it is different enough, post your own question referencing the previous question and clearly mention how it is different.
If your issue is identical but there's no answer, and you can post a better question with more in-depth diagnostic information (things you couldn't edit into the original question because it would change the meaning), there's a reasonable chance that the other question ought to be closed as a duplicate of yours - make a case for it: "While this is similar to the previous question, I've noticed a few things they missed that I couldn't edit in".

A:

You can also promote the question - share it on Twitter, blog about it, send a link to a mailing list you're on or a related Slack. Be sure to use the link from the share under the post, creating a URL that includes your ID. That will enable you to earn badges (Announcer, Booster, Publicist) for sharing links that other people follow. Include extra detail where you share, if you can't or won't add it to the question.
