How to Check Ubuntu Version

If you are using Ubuntu, it is important to know the version you are running. By knowing the version, you can determine if your system is up to date and if it is compatible with certain software. In this article, we will show you how to check your Ubuntu version using the command line.


Before we proceed, ensure that you have access to a Ubuntu system and a terminal application.

Checking Ubuntu Version

To check your Ubuntu version, follow the steps below:

  1. Open a terminal application by pressing Ctrl+Alt+T or by searching for “Terminal” in the applications menu.
  2. Type the following command and press Enter:
    lsb_release -a

    This will display detailed information about your Ubuntu version, including the release number, codename, and description.

    No LSB modules are available.
    Distributor ID: Ubuntu
    Description:    Ubuntu 20.04.2 LTS
    Release:        20.04
    Codename:       focal

    The lsb_release command stands for “Linux Standard Base Release,” which is a command-line tool that displays Linux distribution information.

  3. Alternatively, you can use the following command:
    cat /etc/os-release

    This will display similar information about your Ubuntu version.

    VERSION="20.04.2 LTS (Focal Fossa)"
    PRETTY_NAME="Ubuntu 20.04.2 LTS"

    The cat command is used to display the contents of a file, in this case, the /etc/os-release file, which contains information about the operating system.
