it's quite difficult for me to get things working for now. […]
Where do i learn more about linux system so i can get more familiar with it?
You said it was difficult "to get things working" - identify what exactly is it that you're finding difficult, then type that into Google/DuckDuckGo and check the results. If there's anything in that results you don't understand, Google/DDG it further. Keep doing that until you understand everything that you want to about that topic. Then proceed to the next topic.
There are also IRC, Discord and Matrix chat rooms for most Linux distros out there, so if you're unable to find an answer, feel free to hop into one of those channels and ask a question.
ChatGPT is also a decent resource for general understanding - but don't type any commands it suggests (unless you know what you're doing!).
