We run Airtime 2.0.3 on a VPS with Debian 6.00. We installed it following the "automated installation" process described at http://en.flossmanuals.net/airtime-en-2-0/automated-installation/ Our lesson learnt is that this is not the easiest but the more effective way to install Airtime. It also makes easy the upgrade at the newest version simply typing apt-get update and apt-get upgrade.
