I have 3.1.2OS running fine on Fedora 4, but the upgrade to 3.1.3OS seems to have gone a bit wacky.
I stopped Zimbra, and started the install script.
The script detected the existing install fine, asked me to upgrade (as with the 3.11 to 3.12 upgrade).
It was during the existing package removal process that things went crazy. It removed ldap, and a couple of others, then somehow got tripped up, couldn't remove a couple of processes and set a few things readonly. Things scrolled by quickly, so I couldn't catch which ones, and am not sure which log to look in (there's nothing in zimbra.log referring to this incident).
Zimbra was now in a completely non-functional state, so I reverted to the image backup I created prior to the upgrade.
Being potentially insane, I tried this upgrade on the reverted backup and got the same results. Now trying the same thing a 3rd time would prove conslusively that i was crazy, so I reverted the image backup again and decided to live with 3.1.2 until I can sort this out.
I have imaged the botched half installed system, and am ready to provide whatever logs are needed...I'm just not quite sure where this stuff gets logged.
