I'm not a Linux expert, sorry about that.
I recently installed MakeMKV on my Linux system, Ubuntu 22.04.2.
I wanted to rip my collection of HD-DVD, but unforntunately, MakeMKV version 1.17.4 doesn't work at all with HD-DVD (it crashes while attempting to decrypt the disk - exact same result on the Windows version...).
So, I want to remove it from my system, but I can't.
It is not visible among the installed applications. Snap can't find it, and a "sudo apt remove makemkv" doesn't work either.
Again, I'm quite a newbie on Linux

Thanks for your help.
