Less than 5GB of disk space, can't upgrade Discourse

Hey @pfaffman Quick question related to this. I faced the same issue, so I ran du -sh *. None of the file exceeds 1MB.

So I didn’t remove.

but I tried docker image “prune -a”, reclaimed space: 0B.

Anything else I should do?
My issue is related to the latest upgrade I made that lead to app shutdown.
