How to Install Rust on Ubuntu 25.10

---

Rust is a modern, multi-paradigm programming language focused on performance, safety, and concurrency. It guarantees memory-safety without needing a garbage collector, relying on its ownership model instead.

Install Rust via rustup

---

Download and run the installer for the official Rust toolchain (which will install the latest stable version, currently v1.90.0).

curl --proto '=https' --tlsv1.3 https://sh.rustup.rs -sSf | sh

Follow the on-screen prompts. Choose option 1 to proceed with the standard installation, which will install rustc, cargo, rustup, and related components.

After installation you may need to source your shell environment:

source "$HOME/.cargo/env"

Verify the Installation

---

Check that the compiler is installed and reports the expected version:

rustc --version

Output:

rustc 1.90.0 (1159e78c4 2025-09-14)

Install Build-Essential (Optional, for compiling C dependencies)

---

sudo apt update && sudo apt install -y build-essential

Create, Compile and Run a Test Program

---

Create a directory for your Rust test:

mkdir ~/rustprojects && cd ~/rustprojects
mkdir testdir && cd testdir
nano test.rs

Inside test.rs, write:

fn main() {
    println!("Congratulations! You have installed Rust and it works.");
}

Compile and run:

rustc test.rs
./test

You should see:

Congratulations! You have installed Rust and it works.

Update Rust Toolchain

---

To update to the latest stable version when available:

rustup update stable

Done

---

You have now installed the latest stable Rust (v1.89.0) on Ubuntu 25.10. You are ready to build Rust applications, manage dependencies with Cargo, and explore Rust’s ecosystem and tooling.
