How to Download and Install Virtualmin || Ubuntu 20.04

The easiest way to get the install script onto your server, is to login to your server and use wget or curl. For example:


# wget http://software.virtualmin.com/gpl/scripts/install.sh

For Virtualmin Professional, use the command suggested on your Software Licenses page.


Run the Install Script and Configure Virtualmin

Execute the downloaded install script using a command like the following:

sudo /bin/sh install.sh

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.

ssh-keygen -R [hostname or IP]

PHP files prompts downloaded instead of executed in FCGId URL

In "/etc/apache2/mods-enabled/php.conf" (replace php with your filename, depending on the php version you're using - in my case it was php7.2.conf) comment out the following two lines:

SetHandler application/x-httpd-php

SetHandler application/x-httpd-php-source

Restart the apache server via the following command:

sudo service apache2 restart

Now set your webstite to FCGId (Virtualmin -> Server Configuration -> Website options -> PHP script execution mode ) and it should work properly.
