Can't update the supervisor at all, 404 error

Hi everyone! While using Home Assistant OS in a VM (VirtualBox), when trying to update the supervisor, I hit this error:

Update of Supervisor failed: Can't install ghcr.io/home-assistant/amd64-hassio-supervisor:2021.06.3: 404 Client Error for http+docker://localhost/v1.40/images/ghcr.io/home-assistant/amd64-hassio-supervisor:2021.06.3/json: Not Found ("no such image: ghcr.io/home-assistant/amd64-hassio-supervisor:2021.06.3: No such image: ghcr.io/home-assistant/amd64-hassio-supervisor:2021.06.3")

At first, I thought that it was because of a lack of storage, so therefore I increased the size of the virtual drive. However, it seems to be giving me the same error, even after only having 39% of the space used

Does anyone know how I could fix this? Thanks in advance!

same problem here

I have the same problem on a newly installed VM (Home Assistant OS 6.5).
Home Asistant automatically tries to update the supervisor and when it fails it gives the unhealthy status. “Your installation is unhealthy”

I get the error also when manually trying to update the supervisor.

This unhealthy status also prevents me from installing addons

I also tried changing to static IP with DNS 8.8.8.8 and/or 1.1.1.1 (I saw suggested on some posts) and still have the same problem.
