For everyday use, I try to install skype linux version 4.3.
First download the .deb file from the website of skype.
Then dpkg -i skype.deb.
If dependency is not satisfied, then try to install each required dependency all together(not each for one time).
If they can‘t be successfully installed, try apt-get -f install to update the dependency.
That‘s it. Then you can start enjoy the linux skype.....
