When ever I try and update the previous install of Kali to version 2.0 after changing the sources.list file with the new deb-src's I get this error mesages like "Err http://http.kali.org sana InRelease" and "Unable to connect to http.kali.org:http:" looking like that for each deb src. My sources.list contains

deb http://http.kali.org/kali sana main contrib non-free
deb-src http://http.kali.org/kali sana main contrib non-free
deb http://security.kali.org/kali-security sana/updates main contrib non-free
deb-src http://security.kali.org/kali-security sana/updates main contrib non-free

I tried changing them to the previous versions sources.list but that did nothing, actually looked like it failed the same way the original sources.list failed. Anyone have this issue and found a fix?
