Today, I did a fresh install of Kali 1.1.0a.

I updated my "/etcapt/sources.list" file (as specified in the (official documentation) to be the following:

deb sana main non-free contrib
deb sana/updates main contrib non-free
deb-src sana main non-free contrib
deb-src sana/updates main contrib non-free
Then, I did a "apt-get update" without any errors.

Next, when I do a "apt-get install kernel-headers-$(uname -r)", it is unable to locate the package.

Is this because the old kernel headers have been removed from the central package repository?
If so, is there any way that I can install them on Kali version 1.1.0a?
