How to install Webmin on Ubuntu 9.04 by using Ubuntu (.deb) Packages
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
