When I start "emacs" from the terminal Emacs version 28 is opening. I don't know from which package manager, I have installed Emacs.
which emacs
shows: /usr/bin/emacs
I tried removing Emacs with apt-get and snap, but it did not work. How do I remove it?
snap list
If it's a deb package you installed, you need the package name to remove it, so you could list packagesdpkg -l
If you have lots of packages you can of course reduce the number shown withgrep
etc ... These types of commands allow you to find the package/snap/etc name – guiverc Sep 15 '20 at 07:45
