Error updating Home Assistant Core Unknown error, see supervisor

Installed version 2022.11.4 trying to upgrade to Latest version 2022.11.5 but getting

Error updating Home Assistant Core Unknown error, see supervisor

First time I’ve had this problem with upgrading. Other then some automation changes, nothing else has changed. The log file doesn’t point to me anything obvious to look at.

We’ll I’m still having trouble with this error now in trying to upgrade to 2022.12.0 , just started with the last release.

No idea at the moment where to look to attempt to resolve

Open to suggestions?

I gave up troubleshooting this. I think the problem was related to the fact I’ve been running HA for a very long time on Ubuntu 18.04 which is not supported by HA.

I backed up my HA config and installed a clean instance of HA on recommended OS of Debian 11 with HA. Linux - Home Assistant

Restored my backup and everything is working great again, updates working fine, and at least now I’m using an OS that is recommended.

Putting this here in case anyone runs into a similar problem.
