Ubuntu says that OpenShot is not installed. It clearly is, as you can see in this screenshot. I've tried a number of variants, including apt remove openshot*, OpenShot, and so on. All the info I can find says this should have worked. I'd like to remove it because it is unstable on my system.
[EDIT] Here is the output of apt-cache:

[Edit] sudo apt list --installed does not produce any output that lists anything like openshot.
Attempting to install openshot again results in this:
The following packages have unmet dependencies:
openshot : Depends: melt but it is not going to be installed Depends: python-mlt but it is not going to be installed E: Unable to correct problems, you have held broken packages.
