Dependencies | not able to install from Ubuntu Software Center | Ubuntu 14.04

Open System Settings -> Software and Updates -> Ubuntu Software tab -> Download from -> Other -> Select best server -> choose the best server
and update your system once you have selected the best server

In the Ubuntu Update menu, by changing the mirror from non-US to US, I was able to download all the required packages and the problem of dependencies is resolved.

Moreover, Now I am able to install any software from the Ubuntu Software Center.

I had the same problem. I plugged my laptop into a wired internet connection and updated the software repositories. This solved the problem for me.
