Installing Skype

Follow these instructions to install and use Skype on openSUSE Linux 13.1, 13.2 and LEAP-42.1 64-bit editions (this method works on all three).

Download the Skype RPM package from http://www.skype.com/en/download-skype/skype-for-computer/. Don't worry about the old openSUSE version. Note that this is a 32-bit Skype version which does not list the correct dependencies and requires tweaking. Install it, but do not start it yet.

Requirements

Instead, open YaST and go to Software Management. Open it and search for packages named "pulse". Select to install packages such as pulseaudio (the default is 64-bit version for 64-bit Linux), pavucontrol and alsa-plugins-pulse the default version and the alsa-plugins-pulse-32bit version. You may also install other pulseaudio packages if you wish. Next, search for "v4l". Install all libv4l* packages, including the 32-bit versions. Accept changes and finish.

Alternatively issue this command in terminal:

sudo zypper install pulseaudio alsa-plugins-pulse alsa-plugins-pulse-32bit pavucontrol libv4l libv4l-32bit libv4l1-0 libv4l1-0-32bit libv4l2-0 libv4l2-0-32bit libv4lconvert0 libv4lconvert0-32bit libpulse0-32bit

Specify the rpm file you downloaded to zypper install (this will not necessarily pull in all the required packages shown above):

sudo zypper install skype-4.3.0.37-suse.i586.rpm

(Note: exact version of skype may differ from the above example - dependent on if Skype updated).
