Linux 4.7 packages and have been superseded by 4.8 and removed from stretch and jessie-backports. You can see the linux-image-4.7 only because it is still installed on your system. As you can see from apt-cache policy above, it is no longer available in the Debian repository, just as any other linux-*-4.7 packages. I guess you can get linux-headers-4.7 packages from the snapshot repository, or you can upgrade to Linux 4.8.
Missing linux-headers-4.7.8-1~bpo8+1
I'm having trouble getting VirtualBox to work on Debian on my laptop: Manufacturer: ASUSTeK COMPUTER INC.
