Bug#1018158: Nvidia driver issue xserver-xorg-video-nvidia depends on non existing package

[J.Hopkins]

Package:xserver-xorg-video-nvidia

Dear maintainer,
                https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1005311
was closed as regarded fixed,

Unfortunately that is not the case after recent update.

since updating today the nvidia driver package doesn't work anymore.
It depends on xserver-xorg-video-nvidia which has unmet dependencies itself.

Depends: xserver-xorg-core (< 2:1.20.99) but 
Package: xserver-xorg-core 2:21.1.4-1
is presently the version available 

Error line is xserver-xorg-video-nvidia : Hängt ab von: depends on
xserver-xorg-core (< 2:1.20.99) but 2:21.1.4-1 to be installed
you have broken packages

Error occurrs in Bullseye with backported driver and also tested with 
Tesla 470 in sid

A timely fix is badly needed as a large number of supported users depend
on working NVidia graphics drivers.

 Best regards  J hopkins
