Broken/incomplete Ubuntu upgrades – Fix

If you encounter power outage or any other issue which causes your computer to power down abruptly while upgrading Ubuntu from one version to newer, you are more likely to get a broken ubuntu upgrade. This can be fixed if you are able to get to a terminal in the broken system.

On terminal,

sudo dpkg --configure -a

installs and configures any remaning upgrade packages


sudo apt-get upgrade --fix-broken

I encountered this issue while trying to upgrade from Ubuntu 13.10 to 14.04. This method fixed my ubuntu upgrade and saved me from a clean install. I hope this works out for others as well.
