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?
When I got into Linux I read every physical book I could. Physical books on a subject tend to be written to have chapters that cover whole material. When you try and learn from multipe ebooks you randomly found online you end up cherry picking bits and pieces and never actually read every chapter, so you miss fundamentals.
Maybe you would benefit by reading a PAPER copy of a book about Linux and the especially command line. Linux is a very command line oriented system so maybe trying to tackle some of the struggles head on will help you unlock
apt
any other tools.
