Problem upgrading from earlier version

[Francisco M Neto]

Greetings!

	I've run into a problem while upgrading this package. 


== apt result:

Error! Bad return status for module build on kernel: 5.7.0-7.1-
liquorix-amd64 (x86_64)
Consult /var/lib/dkms/nvidia-current/450.57/build/make.log for more
information.

dpkg: dependency problems prevent configuration of nvidia-driver:
 nvidia-driver depends on nvidia-kernel-dkms (= 450.57-3) | nvidia-
kernel-450.57; however:
  Package nvidia-kernel-dkms is not configured yet.
  Package nvidia-kernel-450.57 is not installed.
  Package nvidia-kernel-dkms which provides nvidia-kernel-450.57 is not

=======================

Looking at /var/lib/dkms/nvidia-current/450.57/build/make.log, it seems to 
be an issue with GCC's version. Setting either environment variable (either 
CC or IGNORE_CC_MISMATCH) mitigates the problem, as apt runs without 
problems in either case.

PS: I'm not subscribed to the list so please reply to me as well.
