System update broke twice, forced to reinstall twice

I am unable to update my OS. I get the message “Directory Not Empty”, and I cannot resolve the issue. I’ve tried Rebasing, Rollback, and even reset. Please view the GitHub issue for more details:

It seems fishy that it’s just for the temp directory. I haven’t checked but are you sure it isn’t backed by a RAM drive? In that case you might have bad RAM (or I guess that could be the case either way).
