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?
I remember feeling really limited on GNU/Linux; for me, it was the desktop environment. Switching to KDE Plasma gave me back the kind of power and usability I was used to from the GUI.
Besides that, always be sure you’re following tutorials for your specific distro, and a recent version at that. In my early days, I borked my system many times by pasting commands I didn’t understand meant for other distros or older versions of the distro I was running.
On software, I would recommend trying to find FLOSS replacements wherever possible. People often sell Linux as being able to run most windows software, and while that’s true, you’ll almost always have a better experience after taking the time to learn a FLOSS tool written for the platform. Even with proprietary native applications, companies often consider GNU/Linux an afterthought and the experience suffers. If you’re using KDE Plasma, for example, try finding a KDE app at apps.kde.org.
For a distro billed as beginner friendly, I always had issues with Ubuntu too. The most trouble free distros I’ve ever used were Manjaro (which I still use to this day on machines I want to just work out of the box - ignore the hate), and Mint. Manjaro comes with an official KDE Plasma verson too.
