I've got a similar problem to the initial poster. I've got a 4.5.6 FOSS install running on CentOS 5 that presents the same error on upgrade
The above is from an attempt to upgrade over the top of my install, but I've tried 4.5.8, 4.5.10 and 5.0.2 all with the same result. When watching the console I also see "SELECT value FROM config WHERE name = 'db.version'" every time. I've reset both mysql passwords and the ldap password.
Upgrading from to 4.5.6_GA_1044
Stopping zimbra services
Starting logger mysql
I can't upgrade version
UPGRADE FAILED - exiting
I've been unable to find a resolution in the forums here, so I'd appreciate any advice I can get.
