I would consider these types of questions "unanswerable hypothetical questions" because you no longer can test, etc. As such, it would be closed as "no longer reproduced or went away", and you can't really get more information for us when we need to debug things. So, this is really a "Bad Fit" for the site. As Oli said.

@terdon I took your statement and added in some insight from a person of many hats. There's a +6 on your post, but I haven't heard anything against this at the moment, so give it a few days before we prod things.

literally in the help center? Help Center: What topics can I ask about?, "Questions that you should avoid", "Support for versions for Ubuntu releases past their Support or "End of Life" (EOL) — unless the question is asking how to upgrade to a supported release." - there's lack of clarification on "past their Support" which is what this modification proposal proposes to do - actually state what the 'past their support' date is as 'standard support' dates are now defined by Canonical and for each release.

It's not written anywhere for 'end of standard support' - the policy would be written so that it says "past the release's end of life or end of standard support period, whichever is first". You might want to read question comments. (And where were you 3 weeks ago with this comment?)

Voters: This does not need to be reopened or deleted. Simply go through Ask Ubuntu posts where this site shows up and remove them from the posts, or flag the posts for moderator attention.

@muru same procedure as OP, upvote a comment, attempt to retract vote. Read my comment for browser details. (Forgive the crassness, side-effects of COVID vaccine and general tiredness are not a good combo.)

@muru Except I replicated this on a fresh profile on the page without the Back button or anything else. Thereby rendering the statement you just made void, AND on an unrelated question/post.

I was able to reproduce this bug - it's not showing the box to ask to remove the upvote. Chrome Version 89.0.4389.90 (Official Build) (64-bit). This is already a 'feature' in the system, but the box asking you to confirm is not showing up for some reason. Removing feature-request from tags, but leaving support and bug
