How do I use apt-get to update to the latest kernel?

up vote 3 down vote favorite

My current kernel is 3.2.0-26 (my main computer) while on another of my Ubuntu computers, with which I didn't fiddle with unofficial updates, it's 3.2.0-30. Yet the Update manager on my main computer doesn't show available kernel updates. It shows other updates though.
I suspect is due to the fact that in the past I installed multiple mainline kernel versions (not recommended versions), up to 3.5* series.
What I'm after: Either: Fix automatic kernel updates. Or: Learn about a way to check for the latest official ubuntu kernel version and get it manually (I know how to install kernels from debs)
What I have already tried: Uninstalled unused kernels including "the generic one without a number" as per http://askubuntu.com/a/103875/29347 and then also https://ubuntugenius.wordpress.com/2011/01/08/ubuntu-cleanup-how-to-remove-all-unused-linux-kernel-headers-images-and-modules/

Your problem with automatic updates may be because of the mainline kernels or because you removed the "generic" package.
You can update to the latest kernel via apt-get as follows:


sudo apt-get update
sudo apt-get install linux-image-`uname -r`

If you also need the headers (to compile kernel modules such as wireless drivers):


sudo apt-get install linux-headers-`uname -r`

The return I get is 'linux-image-3.2.0-26-generic is already the newest version.' while in fact it's not (please see the original question). Are you sure you gave me the right terminal commands? I'm not an expert in the matter but to me the commands translate to "update kernel to the same version you already have installed and use". – Bucic Sep 14 '12 at 16:48
