I've just switched to bullseye (see sources below)

deb http://deb.debian.org/debian/ testing main contrib non-free
deb-src http://deb.debian.org/debian/ testing main contrib non-free

deb http://deb.debian.org/debian/ testing-updates main contrib non-free
deb-src http://deb.debian.org/debian/ testing-updates main contrib non-free

deb http://deb.debian.org/debian-security testing-security main
deb-src http://deb.debian.org/debian-security testing-security main

deb http://security.debian.org testing-security main contrib non-free
deb-src http://security.debian.org testing-security main contrib non-free

The update and upgrade went fine, but full-upgrade fails due to the following error message:

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.

From what I see on the packages.debian.org, Debian testing should have libgcc-8-dev: 8.4.0-4, so I don't see why an older version is to be installed.

How can I fix this, to finalize the bullseye full-upgrade?

Installing gcc-8-base (sudo apt install gcc-8-base) appeared to do the trick for me and fix the problem for me.

    sweet! I've been going through trying to update the individual packages to no avail, this did the trick though thanks! – flux9998 Jun 17 at 22:35
  • Right now this would even remove apt, so not a good idea. Sadly this isn't a planned transition (release.debian.org/transitions). – MKesper Aug 25 at 6:47

If it still does not work try: apt-get install gcc-9-base

  • worked for me. now im thinking whether gcc-10 would've also worked? – Macindows Sep 9 at 4:48

Clearly there are some broken dependencies.

Got the same issue.

# apt-get dist-upgrade
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.

So, I ran #apt-get install libgcc-8-dev, hoping that it will upgrade the problematic package or get more information. The output was:

The following packages have unmet dependencies:
  gcc-8-base : Breaks: gcc-8-base:i386 (!= 8.4.0-4) but 8.3.0-6 is to be installed
  gcc-8-base:i386 : Breaks: gcc-8-base (!= 8.3.0-6) but 8.4.0-4 is to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

That's how I found that the gcc-8-base package is problematic. Next step? #apt-get install gcc-8-base gcc-8-base:i386. Result: gcc-8-base can be upgraded, but the apt want me to remove about 300 packages (which I don't want to remove, many of them are KDE-related) including gcc-8-base:i386, no alternative. I can work without gcc-8-base:i386, so removed it, but it didn't help.
