I recently updated my Ubuntu from 12.10 to 13.04 using commands:

sudo apt-get update 

and upgraded

sudo apt-get upgrade

After that I did

do-release-upgrade -d

But after sometime my system froze so I forcefully shut it down without letting it complete the up-gradation process. Now, on checking the version from "About This Computer" and from terminal using command

 lsb_release -a

I get contradicting results .The command says "Ubuntu 13.04" whereas GUI shows 12.10. How to fix this?And more importantly, which among the two is correct? Other problems I face are: Sound Setting on top is disabled. I am unable to change them.
