hello everyone,

I am trying to install FSL on ubuntu 14.04 installed on a virtualbox in windows 7. 
in FSL official site it says that you should download it from this site: 
http://neuro.debian.net/pkgs/fsl-complet...
I have done this using ubuntu software center. but it doesn't seem to work! besides the GUI doesn't have any FSL view tabs...
the download size was 70 Meg, which is really less than the one I had downloaded for centOS linux. 
can anyone help me figure out what the problem is? 

thank you in advance
