Lost files after upgrade, got them back, and don't really know why

Can y’all help me grasp what went down here? Went to log into Docker and got a notice about an upgrade. Couldn’t tell if it was a Digital Ocean or Discourse situation, so against my better judgement I decided to run the upgrade. When it finished, my files were gone from /var/discourse. Had a backup, so I wasn’t too worried, but it was still disconcerting what with me not really knowing what I’m doing over here. Especially regretted the “37 files will be removed. Are you sure you would like to continue?” Y response.

You can see me freaking out jumping between directories trying every command I knew. Decided to go with @sam’s rails c solution here. After I did that I had no idea what to do with [1] pry(main)>, so I threw Upload.first at it and it all worked out.

Would anyone be kind enough to help me understand why?

/var/discourse and ~/var/discourse are not the same directory.


Well, that explains a lot. Thanks @mpalmer!
