"No CLI required to install software"
This seems very odd ... a quick one-liner install process is by far the simplest and most efficient way to install a piece of software ...
What other fragility and unnecessary complexity comes along with graphical installation tools ?
Is this a pain point for non-technical users you might prepare this system for ? Who do you have in mind when you specify this ?
Perhaps this exercise will help. You are new to a given piece of software.
A: There is a UI with 2 buttons. How many degrees of freedom is that?
B: There is a text prompt, which accepts any number of unicode characters. How many degrees is that?
It is not simpler, if you don't know the exact magic line that does it for the specific application. GUI tools allow for easy and convenient search.
