You really do need to do some research on these forums and the wiki (and also read the documentation), all your questions have been asked and answered before. Look in the log files and search the forums for the error messages you find.
k sure.I'll try it...thank u for ur kind guidance ....
I know you have already fixed the issue but I wanted to reply and share how I fixed this issue on Ubuntu 10 on Amazon EC2.
1) I opened /etc/hostname
2) Put in the host name before the two amazon provided hostnames
3) Commented out the amazon hostnames by prefixing them with at #
4) restarted the server
Now able to install without this error.
For what is is worth I had set the hostname under /etc/hostnames to server.com well this was a mistake becuase it shouldn't be a FQDN hostname.
For my Windows brothers and sisters out there this should be a netbios name like server not FQDN like server.com.
Anyways hopefully this will help someone out there.
