I did follow the "Automated Installation" guide page.
But while you were replying the above, I gave it another try a different way with no success (I enter the command "sudo apt-get install gdebi" (Lucid) before to start the "Automated installation").
This is informations you ask for :
* Creating /var/log/airtime
* Creating /var/tmp/airtime
* Waiting for media-monitor processes to start...
Starting Airtime Media Monitor: Done.
* Detecting OS: ... Found Ubuntu 10.04.2 LTS (lucid) on amd64 architecture
* Clearing previous pypo cache
* Waiting for pypo processes to start...
Stopping daemon monitor: monit.
Starting daemon monitor: monit.
*** Verifying your system environment, running airtime-check-system ***
My new discussion seems to make sens with this. Would you please have a look and tell me if you can see where I may go wrong (maybe with hostnames...).
