I get this error on upgrading from:
Release 3.1.3_GA_474.SuSEES9_20060609153405 SuSEES9 NETWORK edition

to 3.1.4. So this is a box that has been working (ok, except for the purge thing.. which led me to the upgrade).

Now the box says the /etc/hosts is broken. When I `hostname`, I get mail.xxxxxx.com. When I ping it, dig it from another server... Everything is fine with dns, from other servers. On the box itself I have no problem.

The exact error is:
HTML Code:
ERROR: Installation can not proceeed.  Please fix your /etc/hosts file
        to contain:

        <ip> <FQHN> <HN>

        Where <IP> is the ip address of the host,
        <FQHN> is the FULLY QUALIFIED host name, and
        <HN> is the (optional) hostname-only portion
Any help? my /etc/hosts looks just like that?
HTML Code:
# IP-Address  Full-Qualified-Hostname  Short-Hostname       localhost
xx.xx.xx.xx  mail.xxxxxxxxxxx.com mail
