[xubuntu-users] Dkms failure in update today

[MR ZenWiz]

I'm running Xubuntu 14.04.1 with all the latest updates - except one
(3.13.0-37-generic #64-Ubuntu SMP Mon Sep 22 21:28:38 UTC 2014 x86_64
x86_64 x86_64 GNU/Linux)

I got an update notice today that was labeled "Xubuntu base" (in two
places) but it actually contained a kernel update to 3.13.0.39.

During the update processing, it reported an error in dkms rebuilding
my nvidia driver, claiming it was not an Ubuntu driver.

While this is strictly correct, synaptic shows my nvidia driver as
nvidia-340 (340.46-0ubuntu1-xedgers.14.04.1), which I installed via
synaptic.

Any suggestions?

Thanks.
