just do it like this and see if it leads to the same double-issue
-
open the terminal ( press the “Show Applications” button from the dock-bar - it’s left bottom i think by default in gnome - then write in the “Type to search …” field - “Terminal” and when the results show up click the Terminal icon - you can also Right-Click “Add to Favorites” to have it on your dock.
-
write
a)
sudo apt auto-remove gimp
- write in your sudo/administrator password that you used when creating your account/setting up your machine - hit “Enter/Return” key to confirm even if you didn’t see your password displayed when you keyd it in. repeat if you didn’t input the password correctly.
- next click the Enter/Return key then press “y” to confirm and then “Enter/Return” again
b)
sudo apt update
- hit “Enter/Return” key
c)
sudo apt install gimp
- hit “Enter/Return” key
- hit “y” key + “Enter/Return” to confirm
- if it shows double installed this time try removing it from the software app manager and then repeat the same steps as above. @rootapoottoot
