To install Skype 1.4 Beta on Ubuntu Feisty Go to this offical page on Skype.com and download the .deb package for Ubuntu Feisty 7.04.

If, for any reason, you need to install Skype 1.4 Alpha (not the latest version anymore) follow this.

First you need to install the current stable version of skype. Its in the Feisty repos or you can add the skype repo to your source list.
deb http://download.skype.com/linux/repos/debian/ stable non-free
Once you got current stable version installed you can try new alpha version (which works much better for me) More about it here.
sudo apt-get install libsigc++-2.0-0c2a libdbus-1-3
wget http://www.skype.com/go/getskype-linux-alpha-static
tar -xvjf skype-alpha_staticQT-1.4.0.64-generic.tar.bz2
cd skype-1.4.0.64
