Comment 22 for bug 261816

I had the same kind of issue this morning with nvidia module (kernel 2.6.27-3-generic and nvidia 177.70 update), with this message during the kernel update :

        nvidia (177.68): Unable to locate /var/lib/dkms/nvidia/177.68/source/dkms.conf
        DKMS tree must be manually fixed

(this is because /usr/src/nvidia-177.68 no longer exists)

nivdia-177.70 module was built but not installed.

I've fixed this with dkms, from the command line :

sudo dkms install -m nvidia -v 177.70 -k 2.6.27-3-generic
