I am kind of new to Ubuntu, and I had nothing wrong until I upgraded my system to Ubuntu 13.10. While the upgrading process I got an error message that kismet can not be downloaded, and when I figured out that it is a sniffing tool I thought that I will not need it anyway.
But after installing gpointing-device-settings and some other softwares; I get this error shown below; I have my software installed but I just want to understand why I get this error; why it is related to kismet and do I need to install kismet ?!

Congratulations, you found your first bug. Now to workaround you need to create the user yourself:
