Can't Uninstall A Program (Openshot)

Ubuntu 20.04.3 LTS. Have checked other answers here and nothing is relevant. After I updated Openshot I had two different versions installed at the same time. I deleted one successfully but now the other won't uninstall. I assume some dependencies were taken out?

1. sudo apt-get remove --autoremove openshot-qt
2. sudo apt-get purge openshot-qt

and all similar variations claim that the program isn't installed, but obviously I can still open it and see it. There's nothing in snaplist as I installed it through terminal. In synaptic manager it doesn't seem to be installed.

EDIT: The program was installed by:

sudo add-apt-repository ppa:openshot.developers/ppa 
sudo apt install openshot-qt python3-openshot

I tried to remove / purge etc by typing openshot-qt python3-openshot etc

Solution 1:

If apt tells you the program is not installed, then it not installed within the APT system. It is most likely installed as a snap package. Use

snap list

to see the software installed as a snap.

Use

snap remove <package>

to remove a snap package.
