What I do is:

1. Install Emacs

2. Install Doom (git clone + run a command): https://github.com/doomemacs/doomemacs

3. space g g to invoke magit

You "apt install emacs elpa-magit". Your OS should respect you enough to make it this simple.

It is worth it imo. there is a caveat that you will have to learn a little bit about emacs to effectively use it if you accidentally do something that throws you into a buffer(file). you need to be able to navigate and delete buffers and frames. if you know vim bindings and install doom emacs it helps a bit too since emacs commands are a bit inscrutable and hard to configure well without it.

i don't use emacs as a daily driver anymore but i solely use it for my git stuff.

Magit is one of the two software packages known to make non-Emacs-using people install Emacs only for that package. The other one is Org Mode.
