Install the Rust Programming Language on Ubuntu

Step 1: Install curl

sudo apt install curl build-essential

(build-essential gives you the C linker that Rust needs.)

Step 2: Download and run the installer

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

Step 3: Choose the installation option

The installer shows three options:

1. Proceed with standard installation (the default). Installs the stable toolchain.
2. Customize installation. Choose the toolchain and the profile.
3. Cancel installation.

Press 1 and Enter.

Load Rust into your current shell:

source "$HOME/.cargo/env"

Step 4: Check the install

rustc --version
cargo --version

A first program

cargo new hello
cd hello
cargo run

Cargo creates a project that prints "Hello, world!".

Update and remove

rustup update
rustup self uninstall
