Linux

Fragmentation, there is so many WM, DE, Distros, package managers. This is the beauty of open source but it is also the plague.

Toxic communities, where people are thrashing you if you don't understand sometimes the overly complicated wiki and you dare open a thread in one of the forums to seek for help.

Driver support, sometimes installing your OS requires a lot of manual configuration to make everything work ok your machine the way you want it.

The main challenge is resisting the urge to install Linux on your own. Because you will need help at some point, so start now by asking for help.

And then, when you don't find the solution by yourself don't waste time and ask for help.

In time you will get it enough to know what you're doing.

Lack of backwards compatibility for older versions of software/games requiring older libs. All I see it lots of pointing back and forwards but it doesn't get solved.

Lack of legacy drivers for graphics cards. I want to run a new distribution on my old hardware, using graphics acceleration and no screen-tearing. Is that too much to ask?

If a program is executed through a wm, have it submit errors to the wm as well so I can see why it's not running, instead of seeing a loading cursor for 2 seconds and then nothing.

I want to be able to do 99-100% of what I want to do using a GUI. Even installing drivers and changing settings. I don't want to have to change things in a text editor just so I can have a simple shortcut on the desktop. I've learned how to do it and I can do it in my dreams now, but that doesn't mean I like doing it.

commercial, immutable distro with professional support team. Easy desktop env. like cinnamon, budgie or kde Preinstalled on new devices

Honestly I think Linux has been on a great path with flatpak and appimages and graphical software centers. With BTRFS Snapper system recovery if an update goes wrong is even easier than the windows version to be honest. Honestly the big push now just needs to come from some corporate and also adoption at the early education level. One reason its so hard for people to switch from windows is because most windows users have at this point used windows and nothing else for 20+ years.for those of the millennial generation and gen z they've been trained to use windows literally since childhood. Linux and open source tech being free and open source would make it a great cost savings move forpublicc education institutions and getting newer generations of young people not straight indoctrinated into using exclusively windows is important.

But to do this IT departments need to have corporate fallback for support. We need companies like suse enterprise or redhat etc to do the corporate level support to even think about an endeavor like that.

Understanding what different distros offer and being able to make a educated decision about it. I looked around for a week or so until I found a arch distro that worked, took away the manual installation process as a complete noob, and wasn't all red flags straight away (the example is that a lot of ppl advised against manjaro). I ended up with garuda (which some ppl aren't a fan of because of chaotic-aur, but we have to start somewhere, haven't we) atm which works fine until I am confident enough to do a complete base arch installation the next time.
