I recently updated my Ubuntu from 12.10 to 13.04 using commands:
sudo apt-get update
sudo apt-get upgrade
After that I did
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
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.
