There are only two supported operating systems to run the Supervisor on:
- Home Assistant OS
- Debian 11 (Bullseye)
These operating systems are actively tested and maintained, for use with the Supervisor.
You need to reinstall the host machine running the Supervisor on one of the supported operating systems.
The best approach here is to take a full backup of your current installation from the Supervisor panel, then reinstall your host with one of the supported operating systems.
If the host is a virtual machine or a supported board, you can use our appliance images.
If not, you can get Debian from here and use our convenience installation script. Make sure you make it compliant with ADR-0014, the convenience script will handle most of that for you.
When the new host is set up and you can reach the Home Assistant frontend, you can upload and restore the backup you made earlier.
