How to Install Rust on Ubuntu 22.04 or 20.04


For users, especially developers wanting to try out the Rust Programming language, the following tutorial will teach you how to import and install the latest version on Ubuntu 22.10 Kinetic Kudu, 22.04 Jammy Jellyfish, or 20.04 Focal Fossa Linux LTS.

Update Ubuntu

First, update your system to ensure all existing packages are up to date to avoid potential conflict issues during the installation.

First, update your system to ensure all existing packages are up to date.

sudo apt update

Optionally, you can list the updates for users who require review or are curious to see what is available to update. This can be good if you have a specific you forgot to place; use the apt-hold command.

sudo apt --list upgradable

Proceed to upgrade any outdated packages using the following command.

sudo apt upgrade

Install Dependencies

Before proceeding further, run the following command to install the required packages needed to install and successfully run Rust on your system. The packages are well known and highly used amongst many similar types of installations.

sudo apt install curl build-essential gcc make -y

Once you have completed the required installation of packages in prerequisites, you can now use (the curl command) to download the Rust installation script by executing the following command.

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

Next, you should see an output like the example below with a prompt about installing the default or customizing the installation.

Type 1 and press the ENTER KEY to continue unless you want to customize.

Example:

The installation should take 1 to 5 minutes, depending on your server’s internet speed and hardware.

Note you will need to activate the (Rust environment) for your current shell once the installation is complete. This is done using the following command, which will also be in your terminal output at the end of the installation.

source "$HOME/.cargo/env"

Verify the version build of Rust installed, which will show you it is successfully installed.

rustc -V

Example output:

rustc 1.66.0 (69f9c33d7 2022-12-12)

Note that you have not activated the Rust environment shell if you cannot print out the version build.

Create Rust Sample Project Application

So you have installed Rust and believe it should be working correctly. When installing a programming language on your operating system, the best way to verify is to create a quick test application.

You will make the famous (Hello World) output using Rust for the tutorial.

First, you must create a directory that will serve as a (Workspace).

mkdir ~/rust-projects

Secondly, change the directory to the Workspace and create a sample application with the following command.

cd rust-projects && nano helloworld.rs

Next, enter the following code for the hello world test.

fn main() {
    println!("Hello World, this is a test provided by LinuxCapable.com");
}

Save and close CTRL+O, exit CTRL+X, and compile the program with the following command.

rustc helloworld.rs

This will create an executable application after it has finished compiling. The application will be in your current directory, as shown in the example output below.

ls

Example output:

To run the application you created using Rust, run the program with the execute command:

./helloworld

Example output from the test application as below:

Additional Commands & Tips

Update Rust

Rust can be updated easily as it has its updater built in. So, updating Rust is relatively easy and is done with a simple command in your terminal.

rustup update

Example output:

Remove (Uninstall) Rust

If, in the future, you no longer require Rust on your Ubuntu operating system, run the following command, which will remove the Rust Programming Language installation with its own uninstall script.

rustup self uninstall

Note you will be prompted with the following message in your terminal.

This will uninstall all Rust toolchains and data, and remove
$HOME/.cargo/bin from your PATH environment variable.

Continue? (y/N)

Example output:

Type Y and press the ENTER KEY.

You will then get the following result Rust has been successfully removed from your system.
