Let's begin, shall we?

Click the system indicator icon (is the last one on the panel, the one that looks like a gear) and click the "Software Up to Date" entry in the menu to open the Update Manager tool.

Now click on the “Settings” button, wait for the Software Sources window to appear, go to the “Updates” tab and select the “For any new version” entry from the drop down list of the “Notify me of a new Ubuntu version” option.

Wait for the upgrade tool to gather some information about your system. At this point, we will be notified if you’re computer is compatible with Ubuntu 12.10 or not. If you get a message like the one below, do NOT upgrade!
