It's an echo to this post: Reminder for own (unanswered) question
Sometimes, a question have an answer in commentary or fix the problem in other way. For example, my question latex to lualatex error at compilation , as been fixed by using an up-to-date system as said in comment. So perhaps the question should be closed and put a commentary in the first post to say why.
For example:
It's an old system, an update fixed it
What do you think about it?
Always have the community in mind when performing an action on the site. This holds for virtually everything. In this case, I would agree that closing the question is completely fine, specifying a condition that an updated distribution fixed the problem.
For most things on this site, including performing actions on posts that you don't yet have the privilege of doing, you can always flag a post for moderator attention and explain your situation.
From the Site Moderators Help Centre:
The most common moderator task is to follow up on flagged posts. Every post contains a small flag link, which anyone with 15 reputation can use. Posts can be flagged as spam, offensive, or just general “needs moderator attention” with an explanatory comment or link. Once flagged, a post increments a flag count that shows up in the topbar for every moderator.
If you see anything in the system that is evil, weird, or in any way exceptional and deserving of moderator attention for any reason...flag it! That’s the primary job of a moderator: to look at every flagged post, and take action if necessary.
Moderators also have some special abilities necessary to handle those rare exceptional conditions:
Moderator votes are binding. Any place we have voting — close, open, delete, undelete, offensive, migration, etc — that vote will reach the threshold and take effect immediately if a single moderator casts a vote.
Moderators can lock posts. Locked posts cannot be voted on or changed in any way.
Moderators can protect questions. Protected questions only allow answers by users with more than 10 reputation.
Moderators can see more data in the system, including vote statistics (but not ‘who voted for this post’) and user profile information.
Moderators can place users in timed suspension, and delete users if necessary.
Moderators can perform large-scale maintenance actions such as merging questions and tags, tag synonym approvals, and so forth.
A lot of the moderation work is mundane: deleting obvious spam, closing blatantly off-topic questions, and culling some of the worst-rated posts on the site. The ideal moderator does as little as possible, but those little actions may be powerful, visible, and highly concentrated.
If you have questions about the reasoning behind a moderator's actions, bring them up for discussion on meta. Remember to be constructive and polite; moderators have the best interest of the site in mind, but they may occasionally make mistakes or have to deal with controversial issues on which not everyone agrees.
The privilege to cast close votes on your own questions is granted at 250 reputation. Thus, you should already be able to do this.
