Sometimes ubuntu forgets to update the kernel on upgrade

On an Ubuntu 15.04 computer I could not install linux-headers for the right kernel versions. Turned out that the kernel installed was from an older Ubuntu, that did not have any corresponding kernel headers in the enabled repositories. Doing the apt-get update && apt-get upgrade dance made no difference.

Sneaky.

I did sudo apt-get install linux-generic and bob's your uncle.

This is a bug in the distribution upgrade script. You can install the correct kernel by running: sudo apt-get install linux-generic After a reboot you should have the 4.2 kernel.
