But still unable to install Skype. It gives me the old fashioned several lib dependency errors. Also when I try to install the .deb package downloaded from their site, it gives skype-bin error.

Try to select all the options in

Muon software center>settings>configure software sources>software sources>other Software

and then update, upgrade the sources, also try to select the best server in the settings. It will update all the sources. That's it. It will add the skype sources and will update the dependencies and then you can install directly from the software center.
