I installed version 2.0 kali sana linux and I saw the look of GNOME 4 quite beautiful . but one of the package as hostapd , php5 - cgi was no longer on the Repositories Instead Kali is but newer ones . This article I have a problem is if I install version 2.0 , I can use sources.list of 1.0 to version 2.0 is not added . and if more are influential or not conflicts between packages . Thank you
