Comment 15 for bug 384639

Kaltsi and Andrei: As mentioned above, the nvidia driver doesn't build with your kernel. You will first have to move the nvidia-common file to a temporary location before installing the kernel headers and image. Don't forget to move it back after installation before reboot. Use the commands before for that. Other than that, Zeroth's instructions worked a charm for me.

$ sudo mv /etc/kernel/postinst.d/nvidia-common /tmp && sudo dpkg -i your-kernel-image.deb && sudo mv /tmp/nvidia-common /etc/kernel/postinst.d/
