In this tutorial, we will show you how to install Mono on Ubuntu 18.04 LTS. For those of you who didn’t know, Mono is an open-source platform for developing and running cross-platform applications based on the ECMA/ISO Standards. It is a free and open-source implementation of Microsoft’s .NET framework.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘
sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of Mono on the Ubuntu 18.04 server.
