Installation fails on Ubuntu 8.04 LTS Server 64-bit

Hi,

When I try to install Virtualmin Pro using the install script on a clean Ubuntu 8.04.1 server install, I get an error:

Package webmin is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

FATAL - Fatal Error Occured: Something went wrong during installation: 0
FATAL - Cannot continue installation.
FATAL - Attempting to remove virtualmin repository configuration, so the installation can be
FATAL - re-attempted after any problems have been resolved.
FATAL - Removing temporary directory and files.
FATAL - If you are unsure of what went wrong, you may wish to review the log
FATAL - in /root/virtualmin-install.log

FATAL - File a ticket in the Virtualmin bugs and issues tracker for further assistance.

How could I solve this problem?

Thank you,

Patrick van Elk
