Please help.. I open the software updater but after checking for updates, the machine told me that "the software on this computer is up to date"

Make sure that the Updates tab of your Software Sources checks for any new version and not for Long-term support versions only since 13.04 is not an LTS release, then check for updates again. – Peachy May 26 '13 at 9:25

Open a terminal window and enter

sudo do-release-upgrade

Goto Update Manager if it does not show any upgrade option. click on Settings...

Software Sources window will be opened. Now goto Updates tab and choose For a newer version to Notify me of a new Ubuntu version.

And now check for update. Hopefully you will be able to update your Ubuntu.
