I had the exact same problem and had to run the following from the terminal
Applications | Accessories | Terminal
Add the following line to my /etc/apt/sources.list file by typing
sudo nano /etc/apt/sources.list
Here's the line that I added
deb-src http://archive.ubuntu.com/ubuntu/ jaunty main universe restricted
then by running
sudo apt-get update sudo apt-get build-dep software-properties-gtk
and it fixed everything
