problem configuring dpkg

I didn't have upgraded my Ubuntu for a long time so today i started upgrading it. The first 2 upgrades were ok. During the last one, I left the laptop unattended and when I came back, it was shuted down. I tried to boot but it won't boot. I plugged a live usb in and tried:

sudo mkdir /media/fix
sudo mount /dev/sda5 /media/fix
sudo chroot /media/fix su

And then i tried apt-get update and upgrade but they said they couldn't finish due to too many errors in dpgk. So i tried:

sudo dpkg --configure -a

and after a while, i get this:

dpkg: too many errors, stopping
