Error installing Gerix Wifi Cracker Xubuntu 14.04

I tried installing Gerix Wifi Cracker. Everything is going great until the last step where I'm supposed to install it by typing:

sudo dpkg -i deb.deb 

I then get the following error message:

dpkg: error processing archive deb.deb (--install): unable to open file '/var/lib/dpkg/ Is a directory 

I've only been using linux for about a week and would appreciate any kind of help!

Edit: I followed the guide that was on here How to install Gerix-Wifi-Cracker?

To install software you need to use:

cd directory sudo dpkg -i package_name.deb 

Make sure you are in the proper directory as well
