How To Install Rust on Ubuntu 20.04

If you wish to install Rust on a system running Ubuntu 20.04, you’ve come to the right spot. Rust is a popular programming language that has grown in popularity over the past few years due to its emphasis on safety, speed, and concurrency. In this article, we will demonstrate how to install Rust on Ubuntu 20.04.

Step 1: Update and Upgrade Ubuntu

Before installing Rust, let’s ensure that our Ubuntu 20.04 system is current. Open the terminal and enter the commands below:

sudo apt update
sudo apt upgrade

This will update your Ubuntu 20.04 system’s package lists and install any available updates.

Step 2: Install Rust using Rustup

Now that our Ubuntu 20.04 system has been brought up to date, we can install Rust. Typically, Rust is installed using a tool called Rustup. Rustup is a command-line application that manages our Rust installations. To install Rust via Rustup, please follow these steps:

1. 1. Use the following line in the terminal to download and execute the Rustup installer script:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

1. 1. The installer for Rustup will prompt you to select the installation settings. Enter to continue with the default settings.
   2. Rustup will add Rust to your system’s PATH after the installation is complete. To check the installation of Rust, start a new terminal window and execute the command:

rustc --version

If Rust was installed correctly, the version number should be displayed in the terminal.

Step 3: Verify the Installation

Let’s construct a small “Hello, World!” program to ensure that Rust is operating successfully. Enter the following command in a new terminal window to establish a new Rust project:

cargo new hello-world

This will build a new “hello-world” Rust project in the current directory.

Using the following command will open the project directory:

cd hello-world

Now, using a text editor, open the src/main.rs file and enter the following code:

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

Save the file and then return to the terminal. Type the command below to compile and execute the “Hello, World!” program:

cargo run

If everything is working properly, the terminal should display “Hello, world!”
