Ubuntu used to bring a bit of spit and polish at a time when most Linux distros lacked that. Nowadays it brings nothing worthwhile to the table anymore, it’s just brand recognition, but what it does bring is aggravation for experienced users.
I had this realization a few years ago when I found myself fighting against 20.04 and I asked myself: what exactly is Ubuntu doing for me that plain Debian can’t? The answer was nothing really, so I moved all my Ubuntu VMs over to Debian Bullseye and never looked back.
