I just had this same problem no an upgrade of two nearly identical servers from 10.04 to 12.04.2 AMD64
My Hardware is AMD64, Nvidia chipset, Root is on an md array with lvm2. The 10.04 was full updated just prior to starting the upgrade. During the upgrade ntfs-3g failed too install due to a pre dependency issue. The hostname failed for the same reason finally resolvconf failed to install. The update eventually failed to configure due to too many errors. Rebooting the system failed with a error about the root filesystem being unavailable or not ready. Root was left mounter read only. I was able to recover by the following commands; # mount -o remount, rw / # mount -a #dpkg --configure -a #apt-get install -f Before the apt-get above apt-get refused to install ntfs-3g because hostname was not installed. hostname refused to install because libntfs- 3g75 was not installable. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1095197 Title: package ntfs-3g 1:2012.1.15AR.1-1ubuntu1.2 failed to install/upgrade: ErrorMessage: pre-dependency problem - not installing ntfs-3g To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ntfs-3g/+bug/1095197/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
