hostname must resolve? - Plesk 9 installer Ubuntu8.04

[Michael OBrien]

I'm trying to install plesk 9 on ubuntu 8.04 but while running through the auto installer steps I hit the roadblock
"Your hostname must resolve to the correct IP address of your server"

I'm still learning as I go when it comes to linux/UNIX but if I use gnome-nettool I can use the Lookup tab to resolve the www.hostname.domain.tld to the IP and vis versa. If I omit the www the lookup fails

Do I need to include the www in the host name or should I update the DNS record so that hostname.domain and www.hostname.domain both resolve to the IP address

It turns out it was a problem with my hosts file. I needed to remove the domain name and the parallels installer error was a side effect of the same error i got if i ran commands as sudo http://ubuntuforums.org/showthread.php?t=615579&page=2
