Had the same problem, saved my installation doing the following:
1- after restart, when the computer stops booting, and there is nothing but a black screen with blinking white dash, press and hold together CTRL + ALT + F1 (to get to the console).
2- sudo dpkg --configure -a
3- after all the configuration, sudo halt.

This worked fine for me.
