It might have to do with installing nvidia-364 from the graphics diver PPA.

The second pass at makign the initrd succeded, after the DKMS installs. So... this might be a transiaent error.

I was installign the 364 driver after purging the 361 version and rebooting.

Status changed to 'Confirmed' because the bug affects multiple users.

Thank you for taking the time to report this bug and helping to make Ubuntu better. The relevant dpkg terminal log says:

update-initramfs: Generating /boot/initrd.img-4.4.0-21-generic
cp: cannot stat '/etc/modprobe.d/nvidia-graphics-drivers.conf': No such file or directory
E: /usr/share/initramfs-tools/hooks/copy-nvidia-options failed with return 1.

Since this was a transient error, let's close this bug.
