+1 on NOT restricting either.
Has been wondering for many weeks why I was unable to update. Thought today that I would sit down and figure out why, since I would like to go to 2022.11. Previously a host restart could solve the issue, but now after 10 restart I still haven´t been able to update.
Will try to rename the Portainer container, and see if that works. Thank you for the information 
Solution for me was also to use kill the Portainer container, restart HA/Supervisor and now it is updating without issues.
