I installed Ubuntu 14.04.2 with kernel 3.16.0-41. I was looking for the kernel source but the kernel-source metapackage is pointing at 3.13 and I can't see any source packages refering to 3.16. What should I be looking for?
You can install linux-source from 14.10. In 14.04.2 that kernel is installed.
If you need Ubuntu kernel for development, you can clone it from git.
git clone http://kernel.ubuntu.com/git/ubuntu/ubuntu-utopic.git
