How to downgrade the Kernel in Ubuntu 8.10 the easy way

In case you need to use an older kernel version in your new all shiny Ubuntu 8.10 preloaded with kernel version 2.6.27, there’s a very easy way to do it.

Instead of compiling it yourself and have to build a god forsaken config file for the compilation, you can install a linux-image package from the repositories. If you do a quick

sudo aptitude search linux-image

You can see the fine result:

p   linux-image-2.6.25-2-386 – Linux kernel image for version 2.6.25 on i386

so if you install the package with

sudo aptitude install linux-image-2.6.25-2-386

You’re all set. The kernel will be automatically added to your grub menu.
