How To Install Mono on Debian 10

Install Mono on Debian 10

In this tutorial we will show you how to install Mono on Debian 10. For those of you who didn’t know, Mono is a 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 through the step by step installation Mono on a Debian 10 (Buster) server.

Install Mono on Debian 10 Buster

Step 1. Before we install any software, it’s important to make sure your system is up to date by running these following apt commands in the terminal:

sudo apt update
sudo apt upgrade
sudo apt install dirmngr gnupg apt-transport-https ca-certificates

Step 2. Installing Mono on Debian 10.

First, we import the repository’s GPG key:

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF

Next, add the Mono repository to your system sources’ list:

sudo sh -c 'echo "deb https://download.mono-project.com/repo/debian stable-buster main" > /etc/apt/sources.list.d/mono-official-stable.list'

Then, update the packages list and install Mono:

sudo apt update
sudo apt install mono-complete

To verify if Mono is installed, run the commands below:

$ mono --version
