Problem since 0.105.1: Can't install any new AddOns; can't update existing AddOns; Can't upgrade/downgrade HA

Since the last update I was running into problems with my HA installation on my NUC in a docker environment.

HA itself is running fine, but:

Issues:
I can’t update (tried to update to 0.105.5).

I can’t restore the core system to a snapshot (tried to downgrade via snapshot to 0.104.x; system keeps staying on 0.105.1)

I can’t install a new addon

I can’t update an existing addon

Was able to update supervisor from 200 to 201.

I tried so far:

reboot / restart

hassio su repair

–> successfully

snapshot restore
—> core HA release keeps the same

as normally “404” errors are related to lacking disk space:

the errors are:

My idea is that the HA core is kind of blocked for further changes as it might be “thinking” it is still updating.

Any idea what I can do next?

thanks
