Don't get me wrong. I love Linux and FOSS.
I have been using and installing distros on my own since I was 12.
Now that I'm working in tech-related positions, after the Reddit migration happened, etc. I recovered my interest in all the Linux environment.
I use Ubuntu as my main operating system in my Desktop, but I always end up feeling very limited. There's always software I can't use properly (and not just Windows stuff), some stuff badly configured with weird error messages... last time I was not able to even use the apt command. Sometimes I lack time and energy for troubleshooting and sometimes I just fail at it.
I usually end up in need of redoing a fresh install until it breaks up again. Maybe Linux is not good for beginners working full time? Maybe we should do something like that Cisco course that teaches you the basic commands?
Linux can be frustrating simply because it is so powerful and versatile in the way Windows is not. Unlike Windows, Linux is not a one size fits all approach. It's designed to be customized highly.
I think newbies would be better off with Linux Mint which pretty much works out of the box. This lowers the barrier to entry. As the newbie advances in their knowledge and skill, they can begin to tinker.
It's also not easy being a newbie and getting learning support isn't always easy. A lot of us sysadmins have a tendency to forget from whence they came.
