ubuntu 13.04 skype issue on hp probook m5330m

upgrade to 13.04 was not as smooth as I wanted it to be. during upgrade some custom added repositories were disabled and I was not able to install skype after. there were number of unresolved dependencies until I finally did:


sudo add-apt-repository ppa:xorg-edgers/ppa
sudo apt-get update
sudo apt-get upgrade

only after this 'sudo apt-get install skype' succeed
