Did you try booting into the recovery mode (selected via grub)? You could then try to restart the upgrade with<\/p>\n

sudo apt-get update\nsudo apt-get upgrade\n<\/code><\/pre>\n
You may need to run<\/p>\n
sudo dpkg --configure -a\n<\/code><\/pre>\n
to fix the partially installed packages.<\/p>\n
If the recovery mode is also broken, you could try booting off a live cd and then chroot’ing into your hard drive installation and performing the above steps.<\/p>\n
To chroot into your hard drive installation, first boot off a live cd. You can use the ubuntu install CD for this task, just choose the option “try ubuntu” rather than installing. Once booted, open a terminal and mount your root partition. If your root partition is \/dev\/sda1:<\/p>\n
sudo mkdir -p \/media\/ubuntu\nsudo mount \/dev\/sda1 \/media\/ubuntu\n<\/code><\/pre>\n
Then you need to mount the proc, dev, and sys filesystems into your new environment:<\/p>\n
sudo mount --bind \/dev \/media\/ubuntu\/dev\nsudo mount --bind \/proc \/media\/ubuntu\/proc\nsudo mount --bind \/sys \/media\/ubuntu\/sys\n<\/code><\/pre>\n
Enable networking:<\/p>\n
cp \/etc\/resolv.conf \/media\/ubuntu\/etc\/resolv.conf\n<\/code><\/pre>\n
Finally, chroot into it:<\/p>\n
sudo chroot \/media\/ubuntu\n<\/code><\/pre>\n
From here you can run apt-get and dpkg to fix your system. This is identical to the way that people fix grub using chroot, in case you run into problems you can google something like “grub chroot ubuntu livecd” and find more info.<\/p>\n
