OS: Ubuntu 6.06 LTS (32-bit)
I had an upgrade failure today moving from 5.0.6_GA_2313 to 6.0.3_GA_1915.

First the installer said it did not like my host file (the one 5.0.6 is using) so I made changes until it was happy, and proceeded. After updating the database schema and in the process of updating ldap the install failed.
Here follow my original host file, the new host file accepted by the installer and the tail of the installer's log of the failure. Any ideas or suggestions would be appreciated.
Original hosts file
Code:
127.0.0.1 localhost localhost.localdomain myServer.myDomain.com myServer mail mail.myDomain.com localhost.myDomain.com
# 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
New hosts file
Code:
192.168.7.6 myServer.myDomain.com myServer
192.168.7.6 mail.myDomain.com mail
127.0.0.1 localhost.localdomain localhost
# 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
Note: I tried using 127.0.0.1 for all entries (as to match the first file), but that would not be accepted.

Any ideas would be great, I am guessing it might be some kind of ldap restriction based on accessing IP address?
