Introduction

Knowing which version of Ubuntu you are running can be more important than it first appears. Whether you are installing software, troubleshooting a problem, following a Linux tutorial, or checking whether your system supports a particular feature, your Ubuntu version provides useful information about your operating environment.

Ubuntu releases are updated regularly, and different versions can have different software packages, desktop features, kernel versions, and support periods. A command that works on one release may behave differently on another. For this reason, one of the first things you may be asked to do when getting technical support is check Ubuntu version information.

Fortunately, finding your Ubuntu version is simple. You can use the Terminal, graphical Settings application, system files, or other built-in commands. This guide explains several reliable methods and shows when each method is most useful.

Why Should You Check Your Ubuntu Version?

Before looking at the commands, it helps to understand why Ubuntu version information matters.

Software Compatibility

Some applications require a particular Ubuntu release or a specific version of system libraries. Checking your Ubuntu version can help you determine whether your system meets the application’s requirements.

Troubleshooting

When searching for solutions online, instructions are often written for a specific Ubuntu release. Knowing your version allows you to choose instructions that are appropriate for your system.

Security and Support

Ubuntu releases have different support periods. Knowing your current release can help you determine whether your system is still receiving important security updates.

System Administration

For servers and other Linux systems, administrators frequently need to identify the operating system version before installing packages, configuring services, or performing upgrades.

How to Check Ubuntu Version

There are several ways to find your Ubuntu version. The best method depends on whether you prefer graphical tools or command-line commands.

1. Check Ubuntu Version Using the Terminal

The Terminal is usually the fastest and most reliable method.

Open Terminal by pressing Ctrl + Alt + T. Then enter:

lsb_release -a

Press Enter, and Ubuntu should display information similar to:

Distributor ID: Ubuntu
Description:    Ubuntu 24.04.3 LTS
Release:        24.04
Codename:       noble

The most important lines are usually Description and Release.

The Release value tells you the Ubuntu release number, while the Codename identifies the release by its official development name.

Why Use `lsb_release`?

The lsb_release command is particularly useful because it provides several pieces of information at once. It is also easy to understand, making it a good choice for beginners.

If you only want the release number, you can use:

lsb_release -rs

This produces a shorter result such as:

24.04

For a quick answer, this is one of the easiest ways to check Ubuntu version from the command line.

2. Use the `hostnamectl` Command

Another useful Terminal method is:

hostnamectl

Depending on your Ubuntu installation, you may see output containing information such as:

Operating System: Ubuntu 24.04.3 LTS
Kernel: Linux 6.x.x
Architecture: x86-64

The Operating System line identifies your Ubuntu release.

Why Is `hostnamectl` Useful?

hostnamectl is helpful when you want more than just the Ubuntu version. It can provide information about the operating system, kernel, architecture, hostname, and other system details.

This makes it convenient for troubleshooting and system administration.

3. Check the `/etc/os-release` File

Ubuntu stores operating system identification information in a standard file called /etc/os-release.

You can display it with:

cat /etc/os-release

You may see something similar to:

NAME="Ubuntu"
VERSION="24.04.3 LTS (Noble Numbat)"
ID=ubuntu
VERSION_ID="24.04"
VERSION_CODENAME=noble

The VERSION_ID value provides the numeric release, while VERSION usually gives a more descriptive version name.

Get Only the Ubuntu Version

If you want to extract only the version ID, you can run:

grep VERSION_ID /etc/os-release

The result may look like:

VERSION_ID="24.04"

This method is especially useful on minimal installations, servers, containers, or systems where other commands may not be installed.

4. Check Ubuntu Version From the Settings App

If you use Ubuntu’s graphical desktop environment, you do not necessarily need to use Terminal.

The exact layout can vary slightly depending on your Ubuntu release and desktop environment, but the general process is:

Open Settings.
Scroll down to About.
Look for information about the operating system.
Find the OS Name, OS Type, or Ubuntu version information.

You may see details identifying your Ubuntu release along with information about the processor, memory, disk, graphics, and system architecture.

Why Use the Settings Method?

The graphical method is ideal for users who are uncomfortable with command-line tools. It also provides useful hardware information alongside the operating system details.

However, if you are working on a remote server, the Settings application may not be available. In that situation, Terminal commands are more practical.

How to Check the Ubuntu Kernel Version

It is important to understand that the Ubuntu release and Linux kernel version are not the same thing.

For example, an Ubuntu system might report one Ubuntu release while using a particular kernel version that has been updated over time.

To check the kernel version, run:

uname -r

You may receive output such as:

6.x.x-generic

You can also use:

uname -a

This provides more detailed information about the running Linux kernel and system architecture.

Ubuntu Version vs. Kernel Version

These two terms are sometimes confused.

Ubuntu version tells you which Ubuntu release you have installed, such as an LTS release.

Kernel version tells you which Linux kernel is currently running.

Both can be useful when troubleshooting, but they answer different questions.

How to Check Ubuntu Version on a Server

Ubuntu Server installations often do not include a graphical desktop environment. As a result, Terminal commands are the preferred way to identify the operating system.

Try:

lsb_release -a

If that command is unavailable, use:

cat /etc/os-release

You can also use:

hostnamectl

For server administrators, /etc/os-release is particularly useful because it is part of a standardized Linux system interface and is commonly available on modern distributions.

Checking a Remote Ubuntu Server

If you connect to an Ubuntu server through SSH, you can run the same commands after logging in.

For example:

ssh username@server-address

Then:

cat /etc/os-release

This lets you identify the remote operating system without needing physical or graphical access.

How to Check Ubuntu Version With One Command

If you want a quick solution, there are several choices.

The most beginner-friendly option is:

lsb_release -a

For a compact result:

lsb_release -d

Or:

cat /etc/os-release

If you only need the Ubuntu release number, the following command is convenient:

lsb_release -rs

For many users, lsb_release -a is the easiest command to remember because it clearly labels the information it displays.

Understanding Ubuntu LTS Releases

When you check your Ubuntu version, you may notice that it includes LTS, which means Long Term Support.

LTS releases are designed for users and organizations that want a longer support lifecycle and a more stable platform. They are widely used on personal computers, development systems, servers, and business infrastructure.

Ubuntu also provides interim releases. These typically have a shorter support period and may introduce newer technologies sooner.

Why LTS Matters

Knowing whether your installation is an LTS release can help you understand its expected support lifecycle. It is particularly important for production servers and computers that need long-term stability.

What to Do After Checking Your Ubuntu Version

Once you know your version, you can use that information for several purposes.

Check Software Requirements

If an application requires Ubuntu 22.04 or later, compare that requirement with your installed release before attempting installation.

Follow the Correct Tutorial

Linux tutorials often provide commands for specific Ubuntu versions. Always verify that the instructions match your system when possible.

Check for Updates

If you discover that your Ubuntu release is outdated or approaching the end of its support period, consider reviewing available upgrade options.

Before a major upgrade, it is wise to back up important files and verify that your essential applications and hardware are compatible with the newer release.

Provide Better Technical Support Information

When asking for help online, including your Ubuntu release can make troubleshooting much easier.

Instead of saying:

“Ubuntu isn’t working properly.”

You can provide information such as:

Ubuntu 24.04 LTS
Kernel: 6.x.x
Architecture: x86-64

This gives others useful context and can help them recommend more appropriate solutions.

Common Mistakes When Checking Ubuntu Version

Although checking the version is simple, users sometimes look at the wrong information.

Mistaking Kernel Version for Ubuntu Version

Running:

uname -r

shows the kernel version, not the Ubuntu release.

Checking the Desktop Version Instead

Your GNOME desktop version is different from your Ubuntu operating system version. A command such as:

gnome-shell --version

may tell you the GNOME version, but it does not directly identify your Ubuntu release.

Assuming All Ubuntu Systems Are the Same

Ubuntu Desktop, Ubuntu Server, cloud images, containers, and customized installations may provide different interfaces. Terminal-based commands are often more universal.
