Basically the same as Ubuntu, except I tried with Debian Buster (10). I updated to Debian Bullseye (11) with no major problems. When I updated to Bookwork (12) the update failed. I then managed to corrupt the configuration files on the router….. Hopefully these notes expedite recovery.

Having used Ubuntu for the past many years I have grown use to netplan. This is not native on Debian Buster, so needs to be installed: sudo apt install netplan.io it basically just seems to work.

One of the benefits of Debian is no Snaps! Also a whole pile of other Ubuntu crud is not there!

tl;dr;

Another reason to move away from Ubuntu.
Ubuntu snap system sucks, to disable:

• snap list # to show what snaps are installed
• sudo snap remove program # to remove snaps listed
• sudo apt purge snapd
• sudo apt-mark hold snapd
• apt list –installed | grep snap

It seems like Ubuntu want Snap to work and actively tries to make this so.
