Method 1: The Graphical (GUI) Way
This alternative method is wonderfully simple and works on nearly all modern Linux systems, not just Ubuntu. Instead of running a specific program, this command directly reads and displays the contents of a system configuration file.cat /etc/os-release
An output of aarch64 (or sometimes arm64) indicates that the server uses an ARM-based processor. Many people and cloud providers now choose ARM because these processors are designed to be extremely power-efficient. This efficiency means they consume less electricity to perform their tasks, directly translating into lower operational and hosting costs.In this quick guide, we will show you two simple methods for finding your Ubuntu version: the graphical and command-line methods.
Thankfully, finding your system’s architecture is as easy as finding its version. In your terminal, run the following command:
Method 2: The Command-Line (CLI) Way
Knowing your Ubuntu version is important, but sometimes it’s only half the story. When you visit a software download page, you will often see different files listed for the version and the architecture. This refers to the type of processor your computer uses. Installing software built for the wrong architecture will simply not work, so it’s an essential piece of information to have.If you manage one or more servers, there’s an even easier way. Constantly logging in to a terminal just to check basic stats can be time-consuming. RunCloud allows you to directly check the Ubuntu version of your server from the RunCloud dashboard, alongside other critical server health information. RunCloud makes it incredibly easy to manage your Linux servers by providing a clean, powerful interface for tasks that would otherwise require complex command-line work.The terminal offers the fastest way to get system information if you are a server administrator, developer, or anyone who prefers working with text-based commands. The Command-Line Interface (CLI), or terminal, is a powerful tool that allows you to communicate directly with your computer.
Option A: The Best All-Around Command (lsb_release)
lsb_release -a
Whether you prefer the visual approach of clicking through the Settings panel or the speed of typing a quick command in the terminal, you can now instantly find both your Ubuntu version and system architecture.Type the following command into your terminal and press Enter:
- Distributor ID: This simply confirms that your operating system is Ubuntu.
- Description: This is the most important line for most users. It provides the full, human-readable version name, such as Ubuntu 24.04 LTS. The “LTS” signifies a Long-Term Support release, guaranteeing five-year security updates.
- Release: This shows you just the version number (24.04), which can be useful for scripts or when a guide asks only for the number.
- Codename: Every Ubuntu version has a unique, alliterative codename (such as “Noble Numbat” or “Jammy Jellyfish”).

Even if you are not a server administrator, we recommend you try this out. These commands are simple, safe, and incredibly useful.
Bonus Tip: Checking Your System Architecture (32-bit or 64-bit)
If you are a RunCloud user, you can get this information directly from your server dashboard summary:This will open a screen dedicated to your system’s details. Look for the OS Name line. This line displays your Ubuntu version number and its release type, for example, Ubuntu 24.04 LTS.Whether installing new software, following an online tutorial, or troubleshooting an issue, one of the first questions you’ll face is, “What version of Ubuntu are you running?” Your operating system details are necessary for managing your system’s health and functionality.In your terminal, type the following command and press Enter:
Combining your version (24.04 LTS) with your architecture (x86_64 or aarch64) gives you all the information you need to download the correct software package every time.So, if you’re using a modern, cost-effective cloud server, don’t be surprised to find it’s running on an ARM architecture.While that looks like a lot of information, you only need to focus on one line. The PRETTY_NAME variable gives you exactly what you need in a clean, easy-to-read format: “Ubuntu 24.04 LTS”. If you are using RunCloud to manage your servers, then you can also see this information in the server dashboard summary section:
