Trying to install ZCS 5.0.8 GA Release (open source) on an Ubuntu 6.06.2 server (running in VirtualBox). I just did a standard install for Ubuntu, installed SSH and any requirements for Zimbra and then updated the system. From there I tried to do an install from the latest file on the website (zcs-5.0.8_GA_2462.UBUNTU6.20080709173036.tgz)
Everything seemed to be running fine and then I got the above error message. Checking log file I see this.
Everything resolves properly (domain.name with MX record of mail.domain.name and mail.domain.name with a CNAME record pointing to host.domain.name). The only other related post said that it was a sudoers problem (it is 0440) and that restarting the network fixed it (it didn't).
