How to install dig on Ubuntu or Debian // Crucial Paradigm

Before downloading or install the .deb Webmin package run the following commands, the 1st command will install the tool wget for download packages from the internet,

sudo apt-get install wget

The next set of commands will install some perl-related libraries required by webmin,

sudo apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl libmd5-perl

If you run into any issues running the above perl relatd commands, try running the following first,

sudo apt-get update

Now we can download the Webmin .deb package,

wget http://prdownloads.sourceforge.net/webadmin/webmin_1.480_all.deb

Install the Debian package with dpkg, not Aptitude,

sudo dpkg -i webmin_1.480_all.deb

To access your successful install of webmin, goto https://[serverIP]:10000
