October 13 is a big day for Ubuntu fans. It’s the day that the next version of Ubuntu arrives. If you want to give it a try, download a copy of Ubuntu 11.10, Oneiric Ocelot, burn an ISO copy to a CD or USB stick, pop that into your PC, and follow along.
Before doing anything drastic, like actually installing Ubuntu on your PC, make sure it works first. Only after testing it out for a while, should you reboot your computer and chose the Install Ubuntu option.
