HI,
I have been using Samba Share on my home assistant for 4 years. Samba Share update 12.2.0 came out a few weeks ago but I can’t install it as it gives me this error: “Can’t install homeassistant/armv7-addon-samba:12.2.0: 500 Server Error for http+docker://localhost/v1.43/images/homeassistant/armv7-addon-samba:12.2.0/json: Internal Server Error (“readlink /mnt/data/docker/overlay2: invalid argument”)”
This is usually showing up when the Docker container image storage corrupted. Unfortunately, I am not aware of a way to fix this type of corruption, I did write a script which fixes other corruptions recently, but it likely won’t fix your case.
Unfortunately, the easiest way to resolve this is to take a full backup, download it, and start over with a new installation
