Another thread contains muttering about who's to blame for the fact that Skype doesn't install.
If you want to test Skype, rather than point fingers, download the 32 or 64 bit version of libxss1 from http://www.ubuntuupdates.org/package...n/base/libxss1. Install it. Then install skype-bin and skype packages from regular repos.
Test call was OK, so I assume it's working.
