Additional information

I get this error every time and also in previous versions (before 2021.12). It results in not able to access the Supervisor page to reboot the host. Also with installing updates I press “update” and it show a spinning wheel for a long time and nothing seems to happen. I need to turn of my raspberry pi to start the same update procedure again and then the update will install. Doesn’t mind if this a update for a add-on or OS.
