Bug#981424: libc6-dev: unable to upgrade libc6-dev from buster to bullseye

[Kamaraju Kusumanchi]

Package: libc6-dev
Version: 2.28-10
Severity: normal

Dear Maintainer,

* What led up to the situation?
I am trying to upgrade from Debian Buster to Debian Bullseye. After changing
the sources.list entries, 'apt-get dist-upgrade' fails with

% sudo apt-get dist-upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
Calculating upgrade... Error!
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
libc6-dev : Breaks: libgcc-8-dev (< 8.4.0-2~) but 8.3.0-6 is to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by
held packages.


Trying to install just libc6-dev also fails.

% sudo apt-get install libc6-dev

But I do not have any packages held.

% sudo apt-mark showhold
/* returns no output */


Contents of the new sources.list
% cat /etc/apt/sources.list
deb http://deb.debian.org/debian bullseye main contrib non-free
deb-src http://deb.debian.org/debian bullseye main contrib non-free

Is it possible to tweak the dependencies of libc6-dev such that a simple 'apt-
get install libc6-dev' will work?

Thanks

Temporarily purge libgcc-8-dev ,it will purge gcc and after doing full-upgrade you can install gcc

Thanks, this work around was already mentioned in the stackexchange
link I provided (https://unix.stackexchange.com/a/624583/198064). My
intention of filing this bug report is to make apt-get somehow aware
of this and resolve it by itself.
