About a week ago I setup Ubuntu as my primary OS on an old machine. It is my first time trying a unix based OS (previously windows). It has been ok, but it seems like every time I try to install something I run into problems. The app has the wrong permissions or I don’t have the right packages or I need to change port settings ect… I was expecting a learning curve but I wanted to know if this is something I should expect to be a long term issue or if I will aquire the skills to side step stuff like this over time?
Yes, it will get better over time. You are using an entirely new operating system. Things are different, but aren’t that hard to learn.
My big tip for installing Linux is to use the package managers when possible. Every distro comes with at least one package manager, which can install many pieces of software. On Ubuntu, there are two: snap and apt. (Yes, this is confusing. Canonical is trying to change the way they package software, and it has made their distro harder to use).
Also, what kind of software are you installing that requires different permissions or ports? If you’re trying to set up servers you many be better off with a different approach.
