Kubuntu 21.10

Foxit Reader is unstable as hell on my PC so I want to remove it, but I don't remember and now can't find how it was installed in the first place so I can do it right. dpkg didn't list it, Discover doesn't list it, snap doesn't list it, apt remove doesn't find it.

Now I'm happy just to delete the folder in /opt and delete the task menu icon, but I'd like to do it properly. What might I have missed?

  • First run sudo updatedb. After that, what is the output of locate foxit and locate Foxit? Feb 3, 2022 at 21:13

N.B: You can use the following commands to extract the directory:
