    Default IPv6 error when upgrading from Ubuntu 8 LTS to Ubuntu 12 LTS?

    Hello everyone,

    I had a Zimbra 7.2.1 on Ubuntu 8 LTS, and wanted to upgrade to Zimbra 8 / Ubuntu 12 LTS. So I made a fresh Ubuntu installation, copied the /opt from the old server, and ran ./ This ends up with the following:

    Sun Oct 21 00:03:10 2012 Operations logged to /tmp/zmsetup.10212012-000247.log
    Sun Oct 21 00:03:10 2012 checking isEnabled zimbra-ldap
    Sun Oct 21 00:03:10 2012 zimbra-ldap is enabled
    Sun Oct 21 00:03:10 2012 Initializing ldap...
    Sun Oct 21 00:03:10 2012 *** Running as zimbra user: /opt/zimbra/libexec/zmldapinit
    IO::Socket::INET6: connect: Connection refused at /opt/zimbra/libexec/zmldapinit line 137.

    I googled for quite a while now, and all I could find was timeout problems with IO::Socket::INET (<= no 6 here). Timeout problems may indicate DNS problems, while I see here a "connection refused", which is not a DNS issue IMO.

    zmldapinit line 137:
    my $ldap = Net::LDAP->new("$ldap_master_url") or die "$@";

    My idea now is that the perl Net::LDAP module changed it's behavior and tries to connect (also) via ipv6, while the zimbra ldap server doesn't listen on any ipv6 interface.

    Has anybody some idea how I can get this solved?
    Has anybody already done these steps zimbra7/ubuntu8 => zimbra8/ubuntu12 successfully?

    Thanks for help!

    I had this same issue on a fresh install on a CentOS 6.3 box, and it ended up being that my Puppet configuration overwrote the /etc/sudoers changes that the Zimbra install adds to the file. See Sudoers - Zimbra :: Wiki for what should be in there.

    other things I've seen people suggest is ensuring your /etc/hosts file is formatted correctly and ensuring that your DNS is also correct for the server, but the sudoers is what did it for me. Another thing that I wasted time on was disabling IPv6, both in the OS and via zmlocalconfig per the instructions here: Configuring for IPv4 - Zimbra :: Wiki but that did not help either. Hope this saves you some time!
