Bug#531559: apt: cannot upgrade, "pkgProblemResolver::Resolve generated breaks"
Package: apt
Version: 0.7.21
Severity: normal
I get the following error:
# apt-get dist-upgrade -s
Reading package lists... Done
Building dependency tree
Reading state information... Done
Calculating upgrade... Failed
The following packages have unmet dependencies:
gnome-session-bin: Conflicts: gnome-session (< 2.26.1-5) but 2.22.3-3 is to be installed
gnome-settings-daemon: Breaks: gnome-session (< 2.24) but 2.22.3-3 is to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
It seems to be the same bug as #194224 (that was closed and archived
due to lack of information, but not fixed).
