14.04 Dependencies – Fixing Installation Issues in Ubuntu Software Center

14.04dependencies

I am not able to download and install programs (including vlc and unity tweak tool) from the Ubuntu Software Center. Every time i try to get them, there is a dependency error and i am completely lost now.

I am using Ubuntu 14.04 (64bit).

More Details:

**Package dependencies cannot be resolved**
This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time.

The following packages have unmet dependencies:
