Hi guys!
For 3 days i'm stuck with this problem:
I need to install my nvidia card drivers, so i have to update my kernel headers; no problem, i follow the instruction but nothing worked for me.

E: Unable to locate package linux-headers-4.0.0-kali1-amd64
so i found on this forum various solution but nothing worked for me. I'm a noob, so I'm probably wrong just something simple.

My source file contain only the kali rolling repo

deb http://http.kali.org/kali kali main non-free contrib
deb http://security.kali.org/kali-security kali/updates main contrib non-free
shoud i add something?

but if i go there: http://http.kali.org/kali/pool/main/l/linux/?C=S;O=D i can easily find the linux-image-4.4.0-kali1-amd64-dbg_4.4.6-1kali1_amd64.deb file, that is an update for my kernel, but how do I install it?
I'm really getting crazy, i want to understand what i'm doing wrong, please help me!!
and sorry for my bad English
