There is not a GUI for everything on Windows. There is for a lot of it though, for better or worse. There usually a GUI on most Linux DEs as well, but the answer you’ll see online often involves the console because it’s easily shared and you can just copy/paste it and it’s universal usually. The GUI option requires long tutorials with images telling you where to click. It’s not an improvement. You’re just following a guide not understanding it either way, but the console option is much faster. A GUI is good for applications you understand, but just solving a problem you don’t understand a GUI is cumbersome.

And yeah, having people split has its issues, but that’s what happens when people get a choice. There’s a similar problem between Windows versions too, but Windows 10 has been dominant for a while now so all answers are for that.

You will run into issues, but you have to learn where to look for answers. You’ve had this with Windows too (like the OP here). You just view the issues you’ve had with Windows differently. You’ve learned to deal with it gradually over time, where switching to Linux you’ll have it largely all at once at first as you set things up for the first time and get used to the change. It’s a big change, but you can handle it. You’ve dealt with worse already.

Also, don’t be afraid of the console. It isn’t particularly scary, except you just haven’t used something like it before I guess. It just requires using a keyboard. You use “man [package name]” for the manual. There’s also a fantastic package called TLDR that is similar to man but much shorter and only contains the things you’ll frequently be looking for. I highly recommend it if you try Linux again. It may help.
