Uh, I've used the package repository with GitHub, and I don't remember having to do this! So, I'm not entirely sure what's happening here. I think this might be accidental complexity because there's probably a misconfiguration somewhere...

But on that point I agree, initial set-up can be extremely dauntin due to the amoun of different technologies that interact, and requires a level of familiarity that most people don't want to have with these tools. which is understandable; they're a means to an end and Devs don't really enjoys playing with them (DevOps do tho!). I've had to wear many hats in my career, and was the unofficial dedicated DevOps guy in a few teams, so for better or worse had to grow familiar with them.

Often (not always) there's an easier way out, but spotting it through the bushes of documentation and overgrown configuration can be annoying.
