I am using HA on docker and manage it from Portainer. An update can be initiated by recreating the container with pulling the new container. That fails with error 500. When I try to pull the image manually in the terminal, I als get an error:
docker pull ghcr.io/home-assistant/home-assistant:sha256-8eb4efd97b864b1b6dc77687f07e0394fb79594b8bc5657cbb409d0ab2c84bcb.sig
