How to Check Your Ubuntu Version

Ubuntu, one of the most popular Linux distributions, releases new versions regularly, each with updated features, security patches, and software enhancements. Knowing the exact version of your Ubuntu system is crucial for installing compatible software, applying updates, or troubleshooting system issues. In this article, we will explore multiple ways to determine your Ubuntu version, primarily using command-line methods but also graphical interfaces where applicable.

Checking Ubuntu Version via Command Line

For most users, the command line is the quickest and most efficient way to find Ubuntu version details. Here are several commands to determine which version of Ubuntu is installed on your system:

Using lsb_release Command

The lsb_release command provides a simple way to retrieve distribution information. Run the following command in the terminal:

    lsb_release -a

This will output details such as:

    Distributor ID: Ubuntu
    Description:    Ubuntu 22.04.3 LTS
    Release:        22.04
    Codename:       jammy

If you only need the release version, use:

    lsb_release -r

This command is useful for quick checks and is supported across most Ubuntu versions.

Checking /etc/os-release File

Another way to check Ubuntu version command line style is by examining the /etc/os-release file. This method is useful for script automation:

    cat /etc/os-release

Example output:

    NAME="Ubuntu"
    VERSION="22.04.3 LTS (Jammy Jellyfish)"
    ID=ubuntu
    ID_LIKE=debian
    PRETTY_NAME="Ubuntu 22.04.3 LTS"
    VERSION_ID="22.04"

This method provides structured information and is compatible with newer versions of Ubuntu.

Using hostnamectl

For systems running systemd, the hostnamectl command can also show Ubuntu version details:

    hostnamectl

Look for the Operating System line, which indicates the version of Ubuntu:

    Operating System: Ubuntu 22.04.3 LTS

This command is useful on both desktops and servers.

Checking /etc/issue File

Another lightweight method is to use the /etc/issue file:

    cat /etc/issue

This outputs a concise Ubuntu version string:

    Ubuntu 22.04.3 LTS \n \l

This file is often referenced in older systems or minimal installations.

Using Graphical Interface (GUI)

If you prefer a graphical method, Ubuntu provides a way to find Ubuntu version details through system settings:

    - Open Settings.
    - Navigate to About under the System section.
    - Look for the OS Name and Version.

This method is suitable for desktop users who are unfamiliar with terminal commands.

Determining Kernel Version

Sometimes, knowing the Ubuntu version alone is not enough; the kernel version may also be relevant. Use the following command to check it:

    uname -r

Example output:

    5.15.0-84-generic

For additional kernel details:

    uname -a

This is especially useful for troubleshooting hardware compatibility issues.

Conclusion

Whether using command-line tools like lsb_release, /etc/os-release, or GUI-based methods, checking the Ubuntu version is a straightforward process. Understanding what version of Ubuntu do I have ensures proper package installation, security updates, and compatibility checks. The best approach depends on user preference, whether working in a terminal-heavy server environment or a user-friendly desktop setting. By using these methods, you can quickly show Ubuntu version and stay informed about your system's status.
