I am currently having some issues with installing the 5.02 version on ubuntu as the error below

Installing:
zimbra-core
zimbra-ldap
zimbra-logger
zimbra-mta
zimbra-snmp
zimbra-store
zimbra-apache
zimbra-spell

The system will be modified. Continue? [N] Y

Removing /opt/zimbra
Installing packages

zimbra-core...file not found.
zimbra-ldap...file not found.
zimbra-logger...file not found.
zimbra-mta...file not found.
zimbra-snmp...file not found.
zimbra-store...file not found.
zimbra-apache...file not found.
zimbra-spell...file not found.
./install.sh: line 252: /opt/zimbra/libexec/zmsetup.pl: No such file or directory

after reaching this stage i will not find anything on zimbra folder apart from .history installation file and another file

appreciate some directions on how to actually fix the problem

cheers
