libc6-dev have unmet dependencies in stable-bullseye

["Markus Ritzmann" <debian@cloud42.ch>]

Hi

Currently libc6-dev cannot be installed on bullseye because of unmet dependencies.

Error message:

> The following packages have unmet dependencies:
> libc6-dev : Depends: libc6 (= 2.31-13+deb11u4) but 2.31-13+deb11u5 is to be installed
> E: Unable to correct problems, you have held broken packages.

Step to reproduce:

> docker run --platform linux/amd64 -it debian:bullseye
> echo 'deb http://deb.debian.org/debian bullseye main' > /etc/apt/sources.list
> apt-get clean
> apt-get update
> apt-get install libc6-dev

The problem only exists when "bullseye-updates" is missing from the package sources.

Works:

> $ cat /etc/apt/sources.list
> deb http://deb.debian.org/debian bullseye main
> deb http://deb.debian.org/debian-security bullseye-security main
> deb http://deb.debian.org/debian bullseye-updates main

Does not work:

> $ cat /etc/apt/sources.list
> deb http://deb.debian.org/debian bullseye main

I am not sure if "bullseye-updates main" are absolutely necessary (perhaps someone can tell me). In any case, "bullseye main" is currently in a non-functioning state, without "bullseye-updates main". Thought I'd write this to point that out.

Best,
Markus
