[Ted <1070427@xxxxxxxxxxxxxxxxxx>]

I'm wondering what the status of this bug is as it relates to 12.04 LTS,
or if that would be considered a separate issue.  The Ubiquity issue
causing linux-headers-generic not to be installed was introduced in
12.10.  However, in 12.04 LTS it is still possible for linux-generic or
linux-headers-generic to be manually removed, and the NVIDIA drivers do
not depend on them.

In my case linux-generic and linux-headers-generic were uninstalled.  When or why this happened I am not sure, and it may be been done intentionally by me, but in any case the NVIDIA packages should pull down all of the dependencies they require.  When the headers are not installed jockey reports that the installation was successful even though the kernel module failed to be built.  Installing the drivers using apt-get reports the same "Module build for the currently running kernel was skipped since the
kernel source for this kernel does not seem to be installed." message as the original bug reporter.  Installing the headers fixes the problem.

Googling for '12.04 "kernel source for this kernel does not seem to be
installed"' brings up plenty of reports for both NVIDIA and wireless
drivers.  Perhaps having dkms depend on linux-headers-generic would be
possible?  Whatever the proper solution, drivers in 12.04 should install
properly, pulling down any dependencies they need.

Also, does the 'Fix Released' status for 12.10+ cover existing systems,
or only newly installed systems?  If the fix is in Ubiquity that does
not seem to fully address all the possible cases of this bug arising.

Bug description:
  [Test Case]
  Regression testing only; this is a fix for a regression in the previous SRU of ubiquity, which has not left -proposed.

  [Regression potential]
  minimal

  [Impact]
  The system in question is a Dell XPS 1340. It needs proprietary drivers because it's unable to suspend with the Nouveau drivers.

  Steps to reproduce:

  - Install Ubuntu 12.10 from USB stick
  - Open software-center
  - Go to Edit -> Software Sources
  - Go to the Additional Drivers tab
  - Select the first offered NVidia driver (nvidia-current)
  - Click on "apply changes"

  Expected result:
  - Nvidia module built and installed.
  - Nice build log in /var/lib/dkms/nvidia-current/304.43/build.

  Actual result:
  - Since linux-headers-generic is not installed, the module fails to build and upon rebooting most desktop elements will be absent.
  - /var/lib/dkms/nvidia-current/304.43/build is empty.
  - Here's the apt terminal log:

  Note that if I manually install linux-headers-generic and then
  reinstall the nvidia driver package (much easier to do via the
  terminal, btw) then the driver correctly builds and it works.
