Thought I'd create a distinct thread from the previous one asking about daily use, because I really do want to hear more on people's pain points. Great to know people are generally sounding pretty positive in those posts who recently switched, but want to know your difficulties as well! This way old and new users can share their thoughts, hopefully to inspire a respectful discussion.
Choose your route: spend your time to learn the terminal, then you'll be able to do pretty much anything via SSH, or learn docker and networking basics and you'll be able to do pretty much everything via web interfaces. I'd recommend the latter if you are not strictly interested in learning the OS but just want to build stuff on top of it
