Have you tried to upgrade via the Software Center? (Did that even exist in 10.04?). — Mochan, Dec 10 '12 at 11:29

@isuru-buddhika, have you gone into the Software Sources and enabled upgrading distros? If not, you can follow the steps in this tutorial. The instructions are basic, quick and easy. Let me know how you get on. — Mochan, Dec 10 '12 at 21:21
