Systemctl "kernel.domainname" is not in a separate kernel namespace: unknown")

Hello Dear Community,

I got an error after I ran “apt upgrade” command.

I use Homeassistant-Supervised based on Debian9.

20-08-30 14:23:41 ERROR (SyncWorker_0) [supervisor.docker] Can't start hassio_multicast: 500 Server Error: Internal Server Error ("OCI runtime create failed: systemctl "kernel.domainname" is not in a separate kernel namespace: unknown")

You can see which containers can run and which is dropping error.

The given error was coming after an “apt upgrade” command and a reboot.

I found some connected github issue that is somehow connected for the DNS changes in the newest version of supervisor/dns.

Any idea how to solve this? My Docker Home-Assistant instance cannot be started anymore.

Thank you.

FIXED!

Solution: If you got this error aftern an upgrade of the linux system and applications this is because Docker-CE updated to the newest version and its not working with the HomeAssistant-Supervised version yet! You have to add repository of docker and install a selected older version! After reboot your computer and the containers will automaticly start as always.
