Home Assistant cannot be updated [solved]

Today I wanted to update Home Assistant.
I received the following error message

[140406325699072] Error updating Home Assistant Supervisor: Update of Supervisor failed: Can’t install ghcr.io/home-assistant/amd64-hassio-supervisor:2022.09.1: 500 Server Error for http+docker://localhost/v1.41/images/create?tag=2022.09.1&fromImage=ghcr.io%2Fhome-assistant%2Famd64-hassio-supervisor&platform=linux%2Famd64: Internal Server Error (“Get “https://ghcr.io/v2/”: dial tcp: lookup ghcr.io on [::1]:53: read udp [::1]:48968->[::1]:53: read: connection refused”)

.

curl -v -u $USER:$CR_TOKEN https://ghcr.io/v2/

Could not resolve host: ghcr.io

Is it going to be okay? Or do I have another problem
Thanks for some tips

my resolv.conf was overwritten … for whatever reason
