See bug 1249649... apparently, according to the response there, it was this failure to install tex-common properly that led to a complete failure of the upgrade.
At the end I was left with a system that had lost half the desktop information, had no sound, could not mount remote disks, and couldn't even find the optical drives. Over the years I've had several less-than-stellar experiences upgrading Kubuntu on various machines, but this was without doubt the worst -- all, apparently, because of a failure to upgrade TeX properly (goodness knows how the two are related, or why it happened only on one of the three machines I upgraded; but I've given up trying to understand it and switched to wheezy on the affected machine since I really need that machine to work properly). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1241454 Title: Problem installing tex-common on upgrade to 13.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1241454/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
