Complicated, but hopefully interesting enough for you to read

I am running HA on docker on Ubuntu, and finally decided it was time for me to move off this “unsupported” configuration and onto HA OS. Since I only have one NUC, and since I didn’t want to risk blowing up my current implementation, I decided to install Virtualbox, then load HA OS onto that, and finally restore from a full snapshot onto this new OS. Here is what happened:

  1. I didn’t want to have both systems running at once, but the supervisor always restarts HA after a shutdown so I was tearing my hair out trying to keep the old system down while I brought the new one up. Eventually Ludeeus on Discord gave me some Linux commands that kept the old system down.
  2. The spinning circle for the snapshot restore never finished (after 16 hours i just closed the browser window), but when I looked at the core and supervisor logs they looked fine, with no unexpected errors
  3. Thinking all was now fine, I tried to login to the new instance but got ‘unable to connect to home assistant’.

I’m now really thankful that I retained my original installation, but I would like to make this move so any suggestions are appreciated. Note: I do use the DuckDNS add-on and was wondering if this may have something to do with why the new installation wasn’t able to be accessed.
