List the available linux-headers and linux-image with apt-cache search:
apt update
apt-cache search linux-headers
Install the correct package (based on previous output):
apt-get install linux-headers-4.8.0-kali1-amd64
And or:
apt-cache search linux-image
Installing it with:
apt-get install linux-image-4.8.0-kali1-amd64
