Ubuntu 10.04 Install Errors

Hi there, I am getting this errors when trying to do virtualmin install.

Any solution?

E: Sub-process /usr/bin/dpkg returned an error code (1)
INFO - Installing dependencies using command: /usr/bin/apt-get --config-file apt.conf.noninteractive -y --force-yes install postfix postfix-pcre webmin usermin ruby libapache2-mod-ruby libxml-simple-perl libcrypt-ssleay-perl unzip zip quota
…in progress, please wait…

Are you trying to install VM on a fresh system (for which the installer script is meant), or have you already installed and configured some packages? The error sounds like there’s an issue with the Mailman installation, which should never happen on a fresh Ubuntu.
