I remember it being a pain to install on Mint or Ubuntu, some years ago (probably when they first made a Linux version available).
I did definitely eventually get it running, but found it a bit underwhelming compared to Kdenlive, so haven't really bothered trying it more recently.
There's a script which apparently converts the installer into one more compatible with Debian/Ubuntu/Mint, which may work.
I've not tried it myself, so at your own risk:

Might be worth a try with this?
