a) An additional clue: when I try to install updates, ignoring a first warning, I get the following information.
The following packages have unmet dependencies: libgl1-mesa-dri: Depends: libgcc1 (>= 1:4.1.1) but 1:4.6.1-9ubuntu3 is to be installed Then comes the warning once again and it cannot be ignored, that is, no updates can be installed: Could not calculate the upgrade An unresolvable problem occurred while calculating the upgrade. Please report this bug against the 'update-manager' package and include the following error message: 'E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.' b) I am attaching the contents of /etc/apt. ** Attachment added: "etcApt.tar.gz" https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/884152/+attachment/2623992/+files/etcApt.tar.gz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/884152 Title: Error: Marking the upgrade (from 11.04 to 11.10) - unresolved package dependencies To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/884152/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
