Let me start by saying thank you for doing what you do. Now with that I had a few problems upgrading… nothing I couldn’t fix my self mind you (been using Linux for 21 years now). I have an Nvidia gpu… the upgrade uninstalled the 535/545 drivers so I tried sudo apt ubuntu-drivers install and it told me I had the latest drivers for my card. That was not correct I was using the open source drivers stuck at 600x800 resolution with 4.3 aspect ratio I had to from the terminal sudo apt install nvidia-535-server.
Could there be a script during installation that probed and asks what driver you want? The reason I asked is because some of the windows were stuck on Maximum and I could not Unmaximize them. Kinda hard to navigate like that lol.
Also I got an error using ubuntu-drivers “udevadm hwdb is deprecated. Use systemd-hwdb instead.” Plus I had to fix a list of broken packages as well… Thats it so far because of my Internet connection took me almost 2 hours to fix (most of the time was downloading packages)
