Could not load the Supervisor panel! (after trying to update from 2021.8.8 to 2021.9.2)

Since I am using proxmox, I will have to give a partition size.
I found Installing Home Assistant Supervised on Debian 11
Where I see you participating in the thread.
I will have to take my time and read things and do it slowly. I like to annotate my steps also.
For now, thanks guys for helping me.
