Don't get me wrong. I love Linux and FOSS.
I have been using and installing distros on my own since I was 12.
Now that I'm working in tech-related positions, after the Reddit migration happened, etc. I recovered my interest in all the Linux environment.
I use Ubuntu as my main operating system in my Desktop, but I always end up feeling very limited. There's always software I can't use properly (and not just Windows stuff), some stuff badly configured with weird error messages... last time I was not able to even use the apt command. Sometimes I lack time and energy for troubleshooting and sometimes I just fail at it.
I usually end up in need of redoing a fresh install until it breaks up again. Maybe Linux is not good for beginners working full time? Maybe we should do something like that Cisco course that teaches you the basic commands?
Learning cli tools takes time. My advice: don't do anything unless you are %100 sure what you are doing or you know how to revert whatever you did. When I first started using Linux I used to mess everything up by trying to solve my problems copy-pasting commands blindly. But in time I wanted to know what those commands were are, what each argument did etc. Apart from the cli tools, one can still mess things up with GUI apps if you edit system files blindly. Now this happens for people who want to dive a bit deeper. If you want a less risky swim, there are immutable distros where it's less likely to break things.
I still keep track of what I install and what I change on my system. That helps a lot too.
