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

Apparently the apt resolver made an unsolicited and ugly decision.

But it's difficult to guess without knowing exactly what's the apt
state and configuration, where's the issue. Try to provide more info.

I'm not sure if this is your suggestion, because that's exactly how it
is.

That's correct. But why did you mention it?

Hi,

apt configuration is out of the box except the sources.list:
------------------- deb http://deb.debian.org/debian/ buster main non-free contrib deb-src http://deb.debian.org/debian/ buster main non-free contrib deb http://deb.debian.org/debian buster-updates main contrib non-free deb-src http://deb.debian.org/debian buster-updates main contrib non-free deb http://deb.debian.org/debian buster-backports main contrib non-free deb-src http://deb.debian.org/debian buster-backports main contrib non-free deb http://security.debian.org/debian-security buster/updates main contrib non-free deb-src http://security.debian.org/debian-security buster/updates main contrib non-free -------------------- So nothing special there. What more info you need? These are maybe more just thinking aloud. Well one might think that if new libglvnd0 is backward incompatible with xserver in the 'main' there should be new one in the 'backport'. Or maybe libglvnd0 is 'silently' dependent of such backport package. Just trying to make sense of obviously bad behavior. An other thought was whether this has something to do with Wayland. Pekka

Please, send the resolver debug output at least, as it might shed some
light. Try:

```

At any rate, it literally depends on a single package, libc6, therefore it
should not remove xserver-org (and I haven't spotted such a peculiarity
myself).
