If by chance you understand German this is an excellent beginner course: https://www.math.uni-bielefeld.de/~frettloe/teach/unix20.html otherwise I would grab a book; but I have no specific book to recommend. However, to name some I found interesting after a quick search:
- How Linux Works: What Every Super-User Should Know
- The Linux Command Line
In my first year I had multiple issues with Linux. Mainly because I tried to install stuff that wasn’t meant for my version of the OS but for an older one and I blindly followed the “black market” tutorials how to uninstall and reinstall packages to meet requirements. That corrupted my system and I had to repair it multiple times. Also, I played around with many distros and multibooted them all, destroying my grub once or twice.
Now that I use Ubuntu for a “longer” time, I rarely have issues except hardware specific ones. For example the webcam doesn’t work on my dell laptop because apparently it is not supported right out of the box. But apart from that I have no issues compared to windows (where imho windows 11 is an issue in itself).
