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?
