Open a command line – with root privilegies – and type:
#vim /etc/apt/sources.list
Insert the follow line:
deb http://download.skype.com/linux/repos/debian/ stable non-free
save and quite the editor (type: :wq! and Enter)
Back in command line, just to update the repositories, type:
#apt-get update
Now type:
#apt-get install skype
Nice and Easy! Skype is installed and if everything on instalation was fine, you can see the Skype icon on: Applications > Internet > Skype
Others packages for apt-get you can find in: http://www.apt-get.org
Enjoy!
