Open your list:

sudo vim /etc/apt/sources.list

Add this line at the end:

deb http://download.skype.com/linux/repos/debian/ stable non-free

Update:

sudo aptitude update

Install skype, answer yes to all question(but think for your self!)

sudo aptitude install skype

If you have some problems with audio(like I had) try this lines:


killall pulseaudio
sudo aptitude remove pulseaudio
sudo aptitude install esound
sudo rm /etc/X11/Xsession.d/70pulseaudio


(I’m using Ubuntu 8.10, but also works with Ubuntu 9.10)
