Linux isn’t for you. Trust me, as someone who doesn’t really like using Linux all that much.
If you stick with it, pick one. Stick with it. Use its documentation, not online forums.
You can’t use online forums because CLI on how to do things varies from distro to distro. So a command for Ubuntu is useless somewhere else, most of the time.
That results in following guides and having it stop working part way through. You will never get anywhere like this. When you eventually do get somewhere, you’re going to take some time away, or you’re going to break something on accident. Then you’ll have to set it all up again and likely will have lost some data if you weren’t careful.
I built a server PC for Plex and a few other programs, after a number of years running various temporary projects, like Raspberry Pi servers I felt semi-confident. It was going for about 7 months and now it is stuck in a grub menu and if I am able to get into the desktop everything is fucked up anyway.
Tl;Dr, you are having issues because you went with the most complicated distros. Run some normal ones like Mint in Virtual Machines, get a feel for the process to install a program – 1) manually, 2) from the “Linux store” (package manager) 3) from GitHub.
Anything else is just asking for a frustration headache
Color change, eh? Sounds like B+W makes displays more energy efficient, that should be significant!
