How to uninstall Emacs? (to reinstall it later)

[LoveZorin]

Hello,
I'm having troubles to uninstall Emacs (I'd been trying a bit, mess with it, and wanted to uninstall it, and maybe reinstall it later).

These are the steps I did:

1. Zorin Sotware manager tool
   There I could not uninstall it for some reason.
   
   
2. So I tried:
   sudo apt remove --purge emacs-bin-common emacs-el emacs-gtk
   which uninstall, I think, some parts.

Now, when I go back to the zorin software manager, I see the following:

and when I type emacs on the search bar, I get

If I click remove nothing happens.
If I click on Source, I have the Flathub and the Zorin OS options.
When, I click on the Zorin option, I get

So, the remove button has disapeared, as for the Flathub.

How can I remove the following?

(This has more to do about learning how to completely remove an application. I have nothing about Emacs)

Kinds Regards

Try

apt list --installed | grep emacs
flatpak list

Hi Storm,
This is what I got

[Storm]

There's some left overs from emacs I see. None in flatpak.

sudo apt remove --purge emacs-common emacsen-commoon

should do it

I'm getting this message:

[Storm]

Did you add something to your sources.list while installing emacs or other?

[LoveZorin]

Intentionnaly, at least, I think I did not.

[Storm]

Okay, well welcome to dependency hell
Lets see the source list

cat /etc/apt/sources.list

[LoveZorin]

I guess so

That looks normal.

sudo apt install libenchant-2-2

Do I use 'sudo apt autoremove'?

[Storm]

yeah

sudo apt upgrade && sudo apt autoremove

[LoveZorin]

Done. I've just rebooted. The icon is gone!
