I have recently come across this question (probably abandoned) asking how to file a bug for a specific issue on Ubuntu 10.10. 10.10 will no longer be supported as of April 10th this year, which is about 2 weeks away.
Assuming it's not closed between now and then for some other reason, should this question and others like it be closed as Too Localized after the end date passes? I would tend to think these should be closed (after all, they're no longer officially supported), but I'd like confirmation on it.
Note: http://meta.askubuntu.com/q/2122/18612 talks about questions regarding using EOL releases, but not filing bugs for them.
