Description of problem: I had my SD burned, so I write the image of the OS for a new installation and then restore the snapshot.
HA starts, but the HassOS cannot update. Tha date is that one of the release (16Dec2020).
If I change the host’s date, the error desappear, but if I shutdown the host, it comes back to Dec 2020.
Moreover if I reboot or update, it doesn’t.

This is the log:
