[Pkg-virtualbox-devel] Bug#780939: virtualbox-dkms does not work for backported kernels.

[Omer van der Horst Jansen]

I'm encountering what's probably the same issue.

omer at triton:~$ aptitude show linux-headers-`uname -r`
Package: linux-headers-4.1.0-0.bpo.2-amd64
State: installed
Automatically installed: yes
Version: 4.1.6-1~bpo8+1
Priority: optional
Section: kernel
Maintainer: Debian Kernel Team <debian-kernel at lists.debian.org>
Architecture: amd64
Uncompressed Size: 2,404 k
Depends: linux-headers-4.1.0-0.bpo.2-common (= 4.1.6-1~bpo8+1), linux-kbuild-4.1, linux-compiler-gcc-4.9-x86
Description: Header files for Linux 4.1.0-0.bpo.2-amd64
This package provides the architecture-specific kernel header files for Linux kernel 4.1.0-0.bpo.2-amd64, generally used for
building out-of-tree kernel modules.  These files are going to be installed into /usr/src/linux-headers-4.1.0-0.bpo.2-amd64, and
can be used for building modules that load into the kernel provided by the linux-image-4.1.0-0.bpo.2-amd64 package.
