That's interesting. There seems to be no problems with current packages. Do you have any third party repositories enabled in your system? There might be a package from a PPA missing some of its dependencies and Update Manager refuses to update the package causing the entire upgrade to fail.
Could you also paste the output from command 'sudo apt-get upgrade' to this bug? Hopefully that gives us some information about the package causing the issues... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1100992 Title: Unable to run update manager To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1100992/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
