You will need to enable the default root account on your machine, 

Fern requires the root account to run..

thanks  for the help

how do you enable the root account in ubuntu since they block it...with out 
having to go true terminal each time 

To enable the root account for ubuntu, you have to do this:

root@host:~# sudo passwd root

This will ask you for a new password for root, input your password of choice, 
this will activate the root account.

Reboot machine, and log in as root from the credential dialog.

Then you can fire up Fern-Wifi-cracker.

The other way you can do it is:

sudo python /usr/local/bin/Fern-Wifi-Cracker/execute.py

This will use sudo, and not expose your system.
