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 Reading package lists... Done Building dependency tree Reading state information...
