I tried to install skype 4.3 in my 64 bit Ubuntu 14.04 machine. Previously 4.2 was installed in my system. While I am trying to install skype 4.3 version using this method describe below, after installing it again shows the version 4.2 in the starting page of skype. But when I tried with uname -a it shows the version is skype 4.3. Strange !!
