I try to install Zimbra in Ubuntu 8.04.1 Desktop 386

I using this zimbra installer zcs-5.0.8_GA_2462.UBUNTU6.20080709173036.tgz
Downloaded from
http://www.zimbra.com/community/downloads.html

I extract the file and run the install.sh script

The error prompt out:

ERROR: Installation can not proceeed. Please fix your /etc/hosts file
to contain:



Where is the ip address of the host,
is the FULLY QUALIFIED host name, and
is the (optional) hostname-only portion
My PC ip is
Code:
henry@henry-desktop:~$ ifconfig
eth0      Link encap:Ethernet  HWaddr 00:0b:db:11:93:09  
          inet addr:3.244.4.91  Bcast:3.244.4.255  Mask:255.255.255.0
          inet6 addr: fe80::20b:dbff:fe11:9309/64 Scope:Link

          TX packets:766 errors:0 dropped:0 overruns:0 carrier:0

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1

          RX bytes:124689 (121.7 KB)  TX bytes:124689 (121.7 KB)
Then the /etc/host is
Code:
127.0.0.1 localhost
127.0.1.1 henry-desktop
3.244.4.91 henry henry 

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
I just add one line
3.244.4.91 henry henry

What wrong? What should I do now?

Thank
