It’s so easy they say on the website…
Download the .deb and install.
But problem: the .deb won’t install since it is meant for i386, not for x64.
Some try forcing dpkg to install regardless of the architecture:
dpkg -i --force-architecture skype*.deb
… but only to discover dependency problems…
Solution:
dpkg --add-architecture i386
apt-get update
apt-get -f install
