How to Check Ubuntu Version in Linux Command Line

Ubuntu is a popular Linux operating system used by many people. It is known for being user-friendly and reliable. Ubuntu releases new versions regularly, each with updates and improvements. Knowing your Ubuntu version helps you understand what features and support you have.

Knowing your version is crucial for several reasons. It ensures you install compatible software and receive the right updates. It also helps with troubleshooting problems and getting the appropriate support. Without this knowledge, you might face issues with software compatibility or miss important security updates.

Why You Knowing Your Ubuntu Version

Knowing your Ubuntu version is crucial for several reasons. First, it helps ensure that you can install software that is compatible with your system. Different Ubuntu versions may require specific versions of software or different configuration settings. If you’re not aware of which version you’re using, you might end up with software that doesn’t work properly or causes issues.

Second, being aware of your Ubuntu version helps you stay updated with the latest security patches and software updates. Ubuntu releases new updates regularly, and knowing your version ensures that you can apply these updates to keep your system secure. If you’re on an outdated version, you might miss critical security patches, leaving your system vulnerable to threats.

Furthermore, knowing your version is valuable for troubleshooting. When you encounter problems, support forums or help guides can offer more precise advice if they know your specific version. This makes it easier to find solutions and get help tailored to your system’s needs.

Method 1. Using the lsb_release Command

The lsb_release command is a simple and effective way to check your Ubuntu version from the command line. To get started, open your terminal. You can open the terminal by pressing Ctrl+Alt+T or by searching for “Terminal” in your application menu.

In the terminal, type the command lsb_release -a and press Enter. This command will provide a detailed overview of your Ubuntu version. 

• Distributor ID: Shows the name of the distribution, which will be “Ubuntu”.
• Description: Provides a more detailed description of your Ubuntu release, including its version number and whether it is an LTS (Long-Term Support) release.
• Release: Displays the version number of Ubuntu you are using, such as “22.04”.
• Codename: Indicates the codename for the release, like “jammy” for Ubuntu 22.04.

The lsb_release command is useful because it offers a clear and comprehensive summary of your Ubuntu version, making it easy to understand and use for system maintenance and troubleshooting.

Method 2. Checking the /etc/os-release File

Another way to find your Ubuntu version is by checking the /etc/os-release file. This file contains essential information about your operating system. To access it, open your terminal. You can do this by pressing Ctrl+Alt+T or searching for “Terminal” in your application menu.

In the terminal, type cat /etc/os-release and press Enter. This command will display the contents of the file. You’ll see various lines of information about your Ubuntu version:

• NAME: Indicates the distribution name, which will be “Ubuntu”.
• VERSION: Shows the version number of your Ubuntu system, such as “22.04 LTS”.
• VERSION_ID: Provides a more concise version number, like “22.04”.
• CODENAME: Displays the codename for your release, such as “jammy”.

Method 3. Using the hostnamectl Command

The hostnamectl command is another effective way to check your Ubuntu version. This command is often used to view and set system hostname information, but it also provides details about your operating system. To use it, open your terminal. You can do this by pressing Ctrl+Alt+T or searching for “Terminal” in your application menu.

In the terminal, type hostnamectl and press Enter. The command will display various system details, including information about your Ubuntu version. Look for the line labeled Operating System. This line will show the distribution name and version, such as “Ubuntu 22.04 LTS.”

The hostnamectl command provides a quick and straightforward way to check your Ubuntu version, along with other system information. This method is especially useful if you’re already using the terminal for other administrative tasks.

Method 4. Using the /etc/issue File

You can also check your Ubuntu version by looking at the /etc/issue file. This file contains a short description of your system, which is displayed before the login prompt. To view its contents, open your terminal by pressing Ctrl+Alt+T or searching for “Terminal” in your application menu.

In the terminal, type cat /etc/issue and press Enter. The command will display the contents of the file. You will see a brief description of your Ubuntu version, such as “Ubuntu 22.04 LTS \n \l.” This output gives you the version number and sometimes additional details about the release.

The /etc/issue file is a simple and effective way to check your Ubuntu version. However, it may not provide as much detail as other methods, like lsb_release or /etc/os-release.

Method 5. Using the Neofetch Tool

The Neofetch tool provides a visually appealing way to check your Ubuntu version along with other system details. It displays information in a colorful and easy-to-read format. First, you need to install Neofetch if it’s not already on your system. Open your terminal by pressing Ctrl+Alt+T or searching for “Terminal” in your application menu.

To install Neofetch, type sudo apt update to update your package list, then type sudo apt install neofetch and press Enter. Follow any prompts to complete the installation.

Once Neofetch is installed, type neofetch in the terminal and press Enter. The output will include a summary of your system, including the Ubuntu version, kernel version, and more. Neofetch presents this information in a visually engaging way, making it easy to see your system details at a glance.
