Hi Melty
I suggest that it be noted that Melt >=7 is a required dependency forversion 22.12.21.AFAIK, Debian does not mention that. My sincere apologiesif I (or reliable sources) am/are incorrect.
This versioned dependency is not needed, as you can't install shotcut normally with the wrong melt version, unless you try hard and end up with a Frankendebian.
It appears you're not using Debian but some fork of it, that messed it up.
Best,
