I got a similar problem when running a routine update. I attach the last part of the output from sudo apt-get dist-upgrade -o "Debug::pkgProblemResolver=1"
I am trying to solve it by 1. uninstalling schooltool2008 2. runnning the update 3. reinstalling schooltool. 1 and 2 are going on fine. If a write no other post take for granted step 3 went well too. ** Attachment added: "output.txt" http://launchpadlibrarian.net/16423116/output.txt -- Could not calculate the upgrade: Resolve generated breaks, this may be caused by held packages https://bugs.launchpad.net/bugs/250751 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
