[Pkg-zfsonlinux-devel] Bug#868506: zfs-dkms: installation fails

[Phil Seremin]

Definitely looks like dependency issue.

First I see this apt-get output:

Loading new spl-0.7.6 DKMS files...
Building for 4.9.0-6-amd64
Module build for kernel 4.9.0-6-amd64 was skipped since the
kernel headers for this kernel does not seem to be installed.

Then later I see:

Still present in 0.7.6-1~bpo9+1.
