sudo apt-get update
sudo apt-get upgrade
sudo dpkg --configure -a
sudo apt-get -f install
That could fix your missing dependencies or broken packages.

Hi Rex Bouwense, when I ran "sudo apt-get update" I got the following errors... Do you have any solution for this? These are Certificate errors I guess...
