How do I upgrade Ubuntu to 12.04?
I am using Ubuntu 11 (Ocelot) on my desktop PC, I installed it to run and keep Windows. These days I find I use Ubuntu more and more and Windows less and less. So, now I see Ubuntu 12 is being released real soon, can I update ocelet, or do I have to remove it from my computer and then rinstall Ubuntu 12
