Introduction

Ever found yourself needing to know the exact version of Linux you’re working with? Whether you’re troubleshooting a technical issue, ensuring compatibility with specific software, or planning a hardware upgrade, knowing your operating system’s version can be crucial. This need is particularly pertinent for Ubuntu users. Understanding your Ubuntu version helps in troubleshooting, avoiding compatibility issues, and planning your system upgrades effectively.

In this comprehensive guide, we'll show you how to identify your Ubuntu version using both command line and graphical interface methods. By the end of this post, you’ll be equipped to quickly find your Ubuntu version using your preferred method, ensuring your system remains up-to-date and compatible with all your requirements.

Why You Might Need To Check Your Ubuntu Version

Ensuring Software Compatibility

Running new software on older releases can often lead to compatibility problems. Similarly, updates to existing applications might require newer versions of Ubuntu. Checking your system's version helps avoid these issues by confirming that your device meets the software's requirements.

Staying Secure

New versions of Ubuntu often come with patches for security vulnerabilities. If you're worried about a specific threat, making sure you have the latest version installed can be a critical safety measure.

Troubleshooting Effectively

When resolving problems on your device, knowing your Ubuntu version is crucial. Many issues are specific to certain releases, and almost every tech support professional will ask for this information to provide accurate guidance.

Planning for Upgrades

Before updating your system, it’s important to verify that your device can handle the new version. Older hardware may not meet the technical requirements of the latest Ubuntu releases. Additionally, if you plan on upgrading your hardware, you might need to update your operating system to fully utilize the new components.

The Different Versions Of Ubuntu

Each Ubuntu version is essentially an update to the operating system, released approximately every six months. Ubuntu is also available in various "flavors," which are different desktop environments built around the same core system.

LTS vs. Non-LTS Versions

Ubuntu versions come in two main types: Long Term Support (LTS) and non-LTS. LTS versions are released every two years and are supported for five years, making them ideal for users who prefer a stable and long-lasting environment. Non-LTS versions, on the other hand, are released every six months with nine months of support, offering the latest features but with shorter support periods.

How To Find Out Which Version Of Ubuntu You’re Using

Enough theory! Let’s dive into the methods you can use to identify your Ubuntu version. We’ll cover both graphical user interface (GUI) and command line methods, so you can choose the one that suits you best.

Method 1: Check Your Version Via The GUI Settings

For users who prefer a graphical approach, this method is the simplest:

  1. Click on the "Settings" icon in the system menu.
  2. Navigate to the "About" section in the settings menu.
  3. Your Ubuntu version number will be displayed there.

This method is perfect for those not comfortable with the command line.

Method 2: The lsb_release -a Command

The lsb_release command prints useful information about the Linux distribution you're using. Here’s how to use it:

  1. Open your terminal.
  2. Type the following command and press Enter:
lsb_release -a
  1. The output will include the description and version number of your Ubuntu installation.

Method 3: The cat /etc/os-release Command

The os-release file contains details about your operating system. To access this information, follow these steps:

  1. Open your terminal.
  2. Enter the following command:
cat /etc/os-release
  1. The terminal will display information about your Ubuntu version, including the version number and codename.

Method 4: Check Your /etc/issue File

The /etc/issue file also holds information about the Ubuntu version. To query this file:

  1. Open your terminal.
  2. Type the command:
cat /etc/issue
  1. You’ll receive a straightforward output with your Ubuntu version details.

Method 5: Use The hostnamectl Command

While the hostnamectl command is typically used for managing the hostname of a system, it can also display key information about the operating system, including its version:

  1. Open your terminal.
  2. Run the command:
hostnamectl
  1. The output will include data about your system, such as the kernel version and Ubuntu edition.

Staying Up to Date

Knowing your Ubuntu version is vital for effective system management. To summarize, here are the methods we covered:

  • Via GUI settings for a quick, user-friendly check
  • Using lsb_release -a for detailed release information
  • Accessing /etc/os-release for a file-based query
  • Checking /etc/issue for a direct version output
