I feel your pain, ugh. Setting up certain types of software can be a pain in the ass because there’s almost always dependencies that need to be set up first; in addition, it’s not always clear what you’re supposed to install or how to do it the right way. A lot of Linux-related documentation out there isn’t geared towards beginners and leaves out a lot of important explanatory and contextual information, which just makes it more frustrating. Unnecessarily, in my opinion.

However, I gotta mention that Ubuntu - though widely used - is sorta notorious for being user unfriendly and isn’t always the most appropriate choice for a beginner Linux user. If anyone reading this is thinking about trying Linux for the first time, I would consider Linux Mint. It’s a Linux distro that is actually based on Ubuntu (which is based on Debian), but it works “out of the box” better than most and should be a positive experience for most users. It’s pretty solid.
