I got this from the Ubuntu forums and it worked for me.
1 start PC and let it load to X login screen (after getting X setup popup and choosing continue)
2 do a ctrl+alt+F1 and get to terminal and login.
3 sudo rm /usr/bin/localedef
4 sudo dpkg --configure -a
5 let upgrade finish and when back to the prompt "reboot"
