[ubuntu] Aircrack-ng problems

view story

http://ubuntuforums.org – I am trying to intsall aircrack-ng on my computer so that I can test my Wi-Fi security. I got to the part where I have to open up the folder and edit the common.make to remove the werror. When i delete the werror and try to save, it says that I do not have permission. I am running ubuntu 13.04. (Hardware)
