How To Install Rust on Ubuntu 20.04 LTS

In this tutorial, we will show you how to install Rust on Ubuntu 20.04 LTS. For those of you who didn’t know, Rust, commonly known as Rust-Lang, is a system programming language that is developed by Mozilla and backed by LLVM. Rust is known for preventing program crashes, memory leaks, and data races before it is compiled into binary, thus creating a highly-productive and stable programming environment.

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 of Rust on an Ubuntu 20.04 Focal Fossa server. You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.

Prerequisites

• A server running one of the following operating systems: Ubuntu 20.04, 18.04, and any other Debian-based distribution like Linux Mint or elementary OS.
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Rust on Ubuntu 20.04 LTS Focal Fossa

Step 1. First, make sure that all your system packages are up-to-date by running the following apt commands in the terminal.

sudo apt update
sudo apt upgrade

Step 2. Installing Rust programming language in Ubuntu 20.04.

Run the following command to install Rust:

sudo apt install rustc

Once the installation is completed you can verify the version of Rust using the following command:

$ rustc --version

Output
rustc 1.41.0

Step 3. Create a Rust Project.

First, create a folder that will serve as Workspace, in it create another folder where the file in question will be:

mkdir ~/projects
cd ~/projects
mkdir hello_world
cd hello_world

Now, create the file:

sudo nano hello_world.rs

Paste the following code inside the new file:

fn main() {
println!("Hello, Boss!");
}

Now compile and run the program:

rustc hello_world.rs 
./hello_world

You will see the output of your Rust code:

Hello, Boss!

Congratulations! You have successfully installed Rust. Thanks for using this tutorial for installing the latest stable version of Rust programming language on the Ubuntu 20.04 LTS  (Focal Fossa) system. For additional help or useful information, we recommend you to check the official Rust website.
