Help with multicast update

Hi,

I’m having issues with the multicast plugin. In the logs it states the following:

21-09-07 08:24:10 INFO (SyncWorker_2) [supervisor.docker.interface] Downloading docker image ghcr.io/home-assistant/amd64-hassio-multicast with tag 2021.04.0.
21-09-07 08:24:15 ERROR (SyncWorker_2) [supervisor.docker.interface] Can't install ghcr.io/home-assistant/amd64-hassio-multicast:2021.04.0: 404 Client Error for http+docker://localhost/v1.41/images/ghcr.io/home-assistant/amd64-hassio-multicast:2021.04.0/json: Not Found ("no such image: ghcr.io/home-assistant/amd64-hassio-multicast:2021.04.0: No such image: ghcr.io/home-assistant/amd64-hassio-multicast:2021.04.0")
21-09-07 08:24:15 ERROR (MainThread) [supervisor.plugins.multicast] Multicast update failed
21-09-07 08:24:15 ERROR (MainThread) [supervisor.plugins.manager] Can't update multicast to 2021.04.0, the Supervisor healthy could be compromised!

I tried via root ssh to run a manual update with “docker pull ghcr.io/home-assistant/amd64-hassio-multicast:2021.04” which fails as the docker command is not found.

How can I correct this error? Thank you in advance

Managed to get a bit further, seems the docker container is broken.
