Hello Linux Geeksters. In this article I will show you how to install Skype 4.2 on Elementary OS 0.2 Luna, via PPA.
Because Elementary OS is 100 % compatible with Ubuntu 12.04 Precise Pangolin, we can easily install Skype 4.2 from the Canonical Partner repository. Follow this instructions exactly, in order to get a successful installation:
Add the repository:
$ sudo add-apt-repository "deb http://archive.canonical.com/ precise partner"
Update the local repository index:
$ sudo apt-get update
$ sudo apt-get install skype
