If you need to use Webex, you may find yourself in a bit of a pickle in Saucy as the multi-arch libs were removed from the official repositories. After testing this, am very pleased to state that this works with Webex (which requires 32-bit libraries to run).
The package is actually a zip file, but due to WordPress not allowing zip files, this is shown as an *.odt file. Simply rename it to multiarch.zip and then unzip the file. Fixed two dependencies with libgphoto2 that prevented installation. installing the package led to 109 packages for the i386 architecture being installed in my testing, about 20 MB of downloaded files.
After doing this, Webex works natively and in VM’s. YMMV here, but it works for me.
Let me know if this works for you as well. Do hope this helps.
