Bug#1004276: Installing libglvnd0/buster-backports would remove 197 packages including xserver and mate

[Pekka Sarnila <sarnila@adit.fi>]

Package: libglvnd0
Version: 1.3.2-1

My current libglvnd0 is newest buster-version 1.1.0-1.
xserver-xorg newest (1:7.7+19)
xserver-common newest (2:1.20.4-1+deb10u4)
etc

apt is already the newest version (1.8.2.3)

# apt-get -s install libglvnd0/buster-backports

...
119 upgraded, 7 newly installed, 197 to remove and 1431 not upgraded
...
Remv xserver-xorg [1:7.7+19]
...


libglvnd0/buster-backports should depend on libc6 only. And there is no 
xserver-xorg/buster-backports available.

libgl1/buster-backports, libegl0/buster-backports etc depend on 
libglvnd0/buster-backports
