Update: I made a new experiment on how to replace Debian with the latest Ubuntu, and it did not work. What I learned is that it was a fun experiment, but it did not work; it did work on older versions of Debian and Ubuntu.

I admit I never get tired of doing experiments like changing Ubuntu to Debian without reinstalling. I have Autism Spectrum Disorder, level 1, and that explains it.

I have fun little experiments that I like to do with things I'm interested in as well. I did a series of paintings of what I would have drawn if I drew what I saw when I was in High School. The series of 8 was called Monsters of the Hallway.

Hello FranzOren,

sounds like you are a keen hacker. I think a lot of hackers have autism.

I haven't time to read your earlier posts. Do you end up "bricking" some things? Do you have enough back-up and hardware to survive that?

I know that Ubuntu is derived from Debian, and they use the same .deb packages. I think Ubuntu would change a lot of architectural and configuration files, like stuff in /etc and /usr, and symlinks might get trashed or dead-ended. I guess this is why straight replacement doesn't work. I think Ubuntu's snap app store thing also creates more divergence.

I wonder, are you trying to avoid dual-booting?
