Successfully updated to version 20 in NextcloudPi Docker, but I now have several gb’s of unknown data in /var/ clogging up my small 8gb / partition. / was around 50% full and now it is 100% full post-upgrade. Looking for suggestions on how to clean it up. Here is what you see inside the Docker container.

I’m unsure on where to look in regards to cruft left over from the upgrade on my boot disk.
