Cannot update. "Server must have at least 2GB RAM & 20GB disk space" isn't true.

I'm not sure 20GB is really enough and wonder if the minimum stated on https://www.cloudron.io/get.html ought to be increased to 25GB?

I've got a Cloudron server with a 20GB drive that literally has one app on it which is only using 96.85 MB and it ran out of space and went offline just from auto-updating.

I managed to clear up a little space by running cloudron-support --troubleshoot and the server came back up, but it's still only got 569.02 MB free.

Indeed, I'm now stuck on 9.0.15 and unable to update any further because it says:

Not enough disk space. Updates require at least 2GB of free space. Available: 542.67MB

Any suggestions for how I can clear up a bit more space?

Even though I thought cloudron-support --troubleshoot had already done this, i tried docker system prune -a --volumes again and managed to free up 2.954GB - now updating
