Straight forward Install, just run the following commands:

apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl
wget http://prdownloads.sourceforge.net/webadmin/webmin_1.510-2_all.deb
dpkg –install webmin_1.510-2_all.deb

IF the install fails due to ‘show-versions’ run the command below then ‘dpkg –install webmin_1.510-2_all.deb’ after it completes.

apt-get install apt-show-versions
