How to upgrade from Elementary OS 0.3 Beta to Elementary OS 0.3 Stable:
If you are using Elementary OS 0.3 Beta and want to upgrade your Linux box to Elementary OS 0.3 Stable, you have to replace the elementary beta ppa with the stable one:
$ sudo add-apt-repository --r ppa:elementary-os/daily
$ sudo add-apt-repository ppa:elementary-os/stable
Update the local repository index and remove the elementary beta packages:
