Wait a while while the system collects some information about your device. After that, you will be notified whether your computer is compatible with Ubuntu 13.04 or not.
After a couple of minutes, you will be prompted to confirm that you want to start the process you need. Therefore, click the "Start Update" button if you are ready to update Ubuntu.
At this point, the update process will begin, which will take some time depending on your Internet connection and computer specifications.
At some point, you will be prompted to remove or save some legacy packages. Take a look at them and select “Save” or “Delete”. It is recommended that you get rid of them, but if you decide to leave, remember that they will not work in Ubuntu 13.04, as in previous versions of the OS.
