Bug#996468: closed by Andreas Beckmann <anbe at debian.org> (Re: Bug#996468: nvidia-kernel-dkms won't install for kernel 5.14.0-1 and 5.14.0-2)

Dear maintainers

I finally found how to fix the problem to address the problem:

ERROR: Kernel configuration is invalid.";
\include/generated/autoconf.h or include/config/auto.conf are missing."$
  Run 'make oldconfig && make prepare' on kernel src to fix it.";

... thanks to this link:
