Thank you very much for your enlighten answer :D !
Removing emacs-gtk itself will work as you expect
Yes that’s what I found out with apt show emacs-gtk, it shows all the dependencies but I found it quiet odd behavior (lack of knowledge).
I wasn’t aware of metapackages, something new to put into my knowledge database.
Edit: While writing my replay and searching through the web and my console, even though I wouldn’t have had understood it while reading it… It actually tells me in the description that emacs is a metapackage… Bad reading skills :/ sorry about that !
Description: GNU Emacs editor (metapackage) GNU Emacs is the extensible self-documenting text editor. This is a metapackage that will always depend on the latest recommended Emacs variant (currently emacs-gtk).
If you don’t mind I have a last question. Imagine I want to remove docker-ce, which depends on iptables among others, if I sudo apt remove --purge --autoremove docker-ce, this isn’t going to remove iptables and break my system right? Because it’s used by other packages, system… I guess, no?
I think a more general question would be how can I be sure I not going to fuck my system while removing packages? Maybe I’m to paranoïd and today it’s relatively safe to do so, compared to years ago??
