Public bug reported:
I was doing a distro upgrade from 21.04 to 21.10, then when it arrived
to the nvidia packages the install broke and I later figured out that it
was because on my system cc points to clang.
Granted, apparently gcc is needed instead for the compilation process
(and I got it to work by changing cc to gcc in update-alternatives), but
I think a more explicit error message should have been shown (for
example good cmake build systems do warn the user if an incompatible
compiler is being used) instead of entirely breaking the upgrade process
and leaving me to finish everything manually using the terminal. The
upgrade tool should have checked the compiler that is being used and
temporarily set it to gcc for the nvidia driver.
