I've scoured questions and answers to this, as well as performing a couple of re-installs to make sure I wasn't crazy. Essentially, I'm trying to install the nvidia drivers per the Kali article on the matter. However this line fails: apt-get install -y linux-headers-$(uname -r)
My kernel version is 4.3.0 (old), and so I ran apt-get update && apt-get dist-upgrade and it seemed to work the first time: I had to answer a couple of prompts (things like the options for ssl, restarting services, etc.) and everything ran successfully. But after rebooting, the kernel version is the same. At this stage, this screenshot tells the rest of the story.

It seems that no matter what I do, I can't get this thing updated. And without that, I feel a) not so warm-and-fuzzy about the state of the box and b) lost as to how to fix it and get those nvidia drivers installed.
Here are some posts that were related, but left me wanting.
