GNU Image Manipulation Program Removal

[artist-wavenet]

In my Ubuntu 18.04's Dash menu there are two GIMP installations that show up. Here are the details that show when these two launchers are edited:

GNU Image Manipulation Program 2.10.20
env BAMF_DESKTOP_FILE_HINT=/var/lib/snapd/desktop/applications/gimp-simosx_gimp.desktop /snap/bin/gimp-simosx.gimp %U

GNU Image Manipulation Program 2.10.22
/usr/bin/flatpak run --branch=stable --arch=x86_64 --command=gimp-2.10 --file-forwarding org.gimp.GIMP @@u %U @@

The version numbers in the names was inserted by myself so I can tell them apart.

I strongly suspect version 2.10.20 was installed with a snap command. Version 2.10.22 was installed using the Software Center. I need to remove version 2.10.20. The command:

sudo snap remove gimp

does not work. Nor does:

sudo apt-get remove gimp

How then is version 2.10.20 removed?

snap list

looks like a specific version.
Regular snap version should just be gimp_gimp.desktop.
Yours show as gimp-simosx.gimp.desktop.
So the above command should output the exact version name.

I would guess it's called gimp_simosx

I do not use snaps at all and have removed snapd so can not search for gimp snap version but you can run command

snap list

to see what snaps are installed.

The list should include gimp which may be known by a name and if that is different from just gimp you will need to use command

sudo snap remove name-of gimp

EDIT:
Too slow; beaten to it by deadflowr

I had already done the command:

sudo snap remove gimp_simosx

No version of gimp appears in response to the command "snap list". Yet version 2.10.20 remains in the Dash menu.

First one should be removable by "snap remove gimp-simosx", second one by "flatpak remove org.gimp.GIMP".
