Think I found the problem = host file.
Catch 22 ==
1.when I installed this server (5.0.18) it told me to edit hosts file and remove everything except 127.0.0.1 - localhost.localdomain locahost
I did this, then the install script completed and zimbra 5 ran.
2.When I upgraded (directly from 5.18 to 6.02) it gave me the errors shown in my first post above.
3.When I upgraded from 6.02 to 6.03, it upgraded ok but gave same errors again.
4. Last night, trying to get zimbra+samba to run (from how-to) the Extensions wouldn't install - gave host error
5. I eventually tried re-running the 6.03 install script, and got a message which said the 6.03 script won't run until I add "ip addr + fqdn +dn to your hosts file"
6. once I did that, (didn't re-run 6.03 script) and the extensions installed just fine!
Some sort of different requirements between zim 5 and zim 6 - zim5 wants a "bare" hosts, and zim6 wants it "normal"!?
Problem Resolution - On zcs6 - MAKE SURE YOUR HOSTS file is:
127.0.0.1 localhost.localdomain localhost
1.2.3.4 yourhost.yourdomain yourhost  |
