This worked great! thanks
Apologies… I had gotten frustrated and restored a backup. I just went back to this and still get the same issues on a new try.

Edit: The issue seems to stem specifically from py3clean:

Okay, I seem to have figured it out. This is actually caused by an issue in Ubuntu with different locales, but also affects my system for some reason.
I ended up manually applying the changes listed here and it fixed it. The file to edit is /usr/share/python3/debpython/files.py - just note that it differs slightly from the linked one, but the same additions/changes will work.
So you installed HA Supervised on Ubuntu? 
No, I installed it on Debian. But the only mention of a similar issue I found was for Ubuntu, and the same fix transferred successfully to Debian.

@Tamsy Million thanks for the upgrade guide, used successfully on Chinese NUC was running HA (in docker) + Supervisor on Debian 11 - now after upgrade running Debian 12. (All went smooth as butter, update took around 15 min overall)

when I execute the command ‘dpkg -i homeassistant-supervised.deb’ the system responds with a series of errors:
Are there any special reasons to install HA Supervised?
As stated in many places regarding the HA Supervised installation method:
This installation method is considered advanced and should only be used if one is an expert in managing a Linux operating system, Docker and networking!
Maybe you should reconsider and choose the Home Assistant Operating System (HA OS) instead?
However, running:
sudo apt install bluez cifs-utils nfs-common
before "dpkg -i homeassistant-supervised.deb" should do the trick.
thank you for your answer.
I tried to install bluez, but it seems it depends on several other installations.
The response of the system:
Exactly what distro are you using?
Debian 12.9, but I think it’s time to take your suggestion and go back to HASSOS

Obiviously you did not strictly follow the OP’s guide. Else you have already done this when reaching paragraph 2.1):
Furthermore you did this all as the root user where on the guide it is clearly stated to continue the installation as the unprivileded user you should have created the step before but get temporary root only by running sudo -i:
You should certainly do yourself a favor and go back to HA OS

Thanks!
After all the suffering, finally a solution that works! Thank you!
