Updating / Upgrading Kernel Using DEBs

I have covered how to compile a linux kernel from source. However if you want the quick and dirty and just do an default upgrade you can download the DEB files and install it that way.

Download The Deb Files

Go to http://kernel.ubuntu.com/~kernel-ppa/mainline/ and go to the subfolder of the kernel version you wish to install.

You need to download the DEB files revelant to your system architecture.

If you have a X64 machine you need to download the following:
linux-headers-.....-generic_.........._amd64.deb
linux-headers-........................_all.deb
linux-image-.....-generic_............_amd64.deb

If you have a x86 machine you need to download the following:
linux-headers-.....-generic_.........._i386.deb
linux-headers-........................_all.deb
linux-image-.....-generic_............_i386.deb

Installing The New Kernel

In a console window go to where your DEBs downloaded and run:
sudo dpkg -i ./linux*.deb

Lot of output will be generated including a note saying grub was updated. When you reboot your new kernel should now be listed as default. Bear in mind any modules or software built specifically for your previous kernel will have to be reinstalled/recompiled.
