I am trying to build a custom iso of kali 2 sana iso these are the steps i took and the error msg i recieved
My current system configuation is
Distributor ID: Kali
Description: Kali GNU/Linux 2.0
Release: 2.0
Codename: sana
Default desktop session
running a live instance of kali2.0 with two persistent drives.
I get the same error message whether in both persistent and Live instance
(Some processes like creating a new truecrypt volume did not work with kali1.x persistence but worked well with kali1.x live so i attempted both to create a custom iso - no luck either way)
Any suggestions or work arounds are appreciated
