I am fighting to upgrade my Ubuntu and I am dealing with troubles. I tried to do it with sudo do-release-upgrade
and also from the Software Updater. I tried out a lot of things (here on StackExchange, ChatGPT) but I am still getting the following screen.
I believe I removed all PPAs and third party repositories. Maybe I missed something. I am really not sure.
If I need to provide more info to fix the issue please let me know.
