Installing from deb on Ubuntu

Hi,

I am trying to follow http:// wiki.sourcefabric.org/display/CC/Airtime+1.8.0+Package+Insta llation on Ubuntu Lucid. One instance is pretty fresh and the other not.

I tried

but I get Quote:

Error: 'http://apt.sourcefabric.org' invalid

on non-clean version and Quote:

sudo: add-apt-repository: command not found

on the clean version.

What am I missing. I have the latest apt-get update on both.
