What’s a beginner to do

Well that’s just it; Endeavour is not a beginner distro. It’s not designed to be. Endeavour is Arch with a graphical installer and some modest quality of life improvements for users who are otherwise willing to trawl through the Arch wiki for answers. The welcome app really just seems to be there so that you don’t have to memorize all the commands or set up aliases, etc, if you don’t want to.

So when you ask “am I supposed to X,” the answer is that there really isn’t a set-in-stone workflow to accomplish anything on EOS or Arch; what you’re supposed to do is read the manual, so to speak, and decide for yourself how you want to go about things.

Unlike some other Arch based distros like BlendOS and Manjaro, Endeavour is still very much a DIY distro.

Don’t use GUI package managers, but here, have some GUI package managers.

What GUI package managers are you referring to? EOS doesn’t supply any.

AFAICT they made something more confusing than Arch, not less.

If I’m not mistaken, this is all stuff you should also be doing on Arch. The single difference is that EOS provides a button in their “Welcome” app that will helpfully run a command for you in a terminal for some of these tasks.

Agreed, you get to pick between a system that empowers you to do whatever you like, or an unborkable system. If you need something that won’t let you shoot yourself in the foot, you ought to be using an immutable distro.

For ages I blamed GNU/Linux for breaking when I was unknowingly causing issues. These days, I don’t fix what isn’t broken, and if I can’t help myself, I make sure I understand what I’m doing, write down any changes I make, and ensure I have a snapshot ready in case things don’t work out.

GNU/Linux may not exclusively be for advanced users anymore, but system customization still is.

Initial setup can be hard, and then, because GNU/Linux lets you do whatever you want, It’s not hard to bork the system if you’re using commands you don’t understand. The biggest realization for me was that if I want a stable system, I can’t expect to experiment with it / customize it to the nth degree unless I have a robust rollback / recovery solution like timeshift in place. Feeling very empowered after leaving windows, I have destroyed many systems, but truly, if you set up your system and then leave it alone, these days it’s not difficult to have a good experience.

But yea, you’re totally right: the userbase can be toxic AF, and there’s no one place you can go to learn the basics you really ought to know.
