Being new to Ubuntu I was lucky not to screw up the /etc/apt/sources.list file:
A safer option is to go to the 'system' menu
Open SYSTEM/ADMINISTRATION/SOFTWARE SOURCES
Enter Password
Select 'Third party software' tab
Click on Add
Cut and Paste the complete following line
deb http://download.skype.com/linux/repos/debian/ stable non-free
then close
Now open Terminal APPLICATIONS/ACCESSORIES/TERMINAL
Enter sudo apt-get install skype
It will install Skype and be ready to go under Applications/ Internet/Skype
