Comment 34 for bug 1070427

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.
