@gadepall, it seems like you might have been temporarily unable to reach the required servers, or forgotten to configure the repository properly. Please try:
sudo add-apt-repository ppa:vanvugt/unity sudo apt-get update sudo apt-get upgrade
If that fails please contact the Ubuntu forums for further help, because I don't believe there is a problem with the PPA.
