Thanks for catching that. That was not intended. There shouldn't be a
dependency (or first alternative dep) on a non-unique virtual package at
all. Apt doesn't like that since it cannot rank the choices. (Even if in
this case there might be only one valid solution.)
I think that virtual package has grown two uses over time:
1.) a Provides/Conflicts relation to prevent co-installation of some
corresponding packages from src:nvidia-graphics-drivers and
src:nvidia-graphics-drivers-tesla-470 if the upstream version matches to
prevent file conflicts.
2.) a Provides/Depends relation to ensure the correct version of the
firmware file is available.
I'll think about that and fix it in src:nvidia*, but that shouldn't stop
you from improving the scripts. ;-)
