I have Home Assistant Operating System on a Raspberry, which has been functioning correctly for some months already. Since last week, it fails. Apparently it does not get access to internet. I can still manage devices within my internal network, but cannot conect to external things.
I cannot update the Home Assistant Supervisor. Currently I have the following version:
Home Assistant 2023.3.6 Supervisor 2023.03.2 Operating System 9.5
When I try updating, I get the error:
Error updating Home Assistant Supervisor: Abort update because of an issue with AppArmor: Can't fetch AppArmor profile https://version.home-assistant.io/apparmor.txt: Cannot connect to host version.home-assistant.io:443 ssl:default
Restarting HA or the router does not solve the problem. Nothing has changed in the configuration since it was working properly. The only fact that comes to my mind, because of what I read in posts here, is that last week they changed the hour in Spain.
Thank you very much.
