The latest stable Linux Kernel has just been released and chances are you not running it and that’s just fine. This short guide is going to show you how to upgrade to it in Ubuntu 3.04 Raring Ringtail and previous if you need to.
It seems like every two to three weeks, there are updates to the Linux Kernel. Updates that enhance and fix issues that were discovered from the previous released versions. Upgrading to the latest Linux Kernel is a nice thing to do as long as your system supports it. Kernel updates are there to enhance, fix bugs, patch security holes, and sometime introduce new features.
So it’s a good thing to upgrade, but remember to always make sure your system supports it because upgrading to an incompatible kernel may render your system unusable.
