Supervisor was not able to update

The issue

This can happen when there was a network issue during the startup of the Supervisor.

The solution

Manually update the Supervisor, in case there is an update pending. This can be done from the Updates panel.

This can also be done with the CLI, by running the following command:

ha supervisor update

In case this doesn’t work. Check the logs, if there’s an error where a host can’t be resolved (eg: lookup no such host) there might be a problem with your network settings (eg: dns server that can’t be reached).
