Ubuntu (Linux)

If you’re an Ubuntu user and you need to find out which version of the operating system you’re using, this guide is for you. Knowing the version number can help you troubleshoot issues, install the right software, or check if your system is updated with the latest security patches. There are different ways to find the version of Ubuntu installed, but many users prefer using command-line methods because they are fast and accessible. Command-line tools can provide detailed information about the installed Ubuntu, including the release number and codename, which are useful for support and software package management. Checking the version is a straightforward process that can be done quickly using built-in terminal commands.

Finding Your Ubuntu Version

Knowing your Ubuntu version is crucial for troubleshooting, software compatibility, and staying on top of updates. Luckily, it’s easy to find out which version you’re running with a few simple commands.

Command Line Methods

For those comfortable with the terminal, here are the most reliable ways:

  • lsb_release -a: This command gives you detailed information about your Ubuntu distribution. Look for the “Description” line, which shows your Ubuntu version and codename (e.g., Ubuntu 22.04 LTS (Jammy Jellyfish)).
  • cat /etc/os-release: This command displays a plain text file containing your system’s information, including the version ID and name.

GUI Method

If you prefer a graphical interface, follow these steps:

  1. Click on the “Activities” overview (usually the top-left corner of your screen).
  2. Search for “Settings” and open it.
  3. Click on the “About” section.
  4. Your Ubuntu version will be displayed under “OS Name.”

Verifying Ubuntu Version Details

Knowing the Ubuntu version on a machine is important for compatibility and security. Various methods exist for checking the details such as command line tools, system files, and graphical user interfaces.

Using Command Line Tools

The terminal is a quick way to find Ubuntu version details. Users can open the terminal and type lsb_release -a which provides information like the distributor ID, description, release number, and codename for the installed Ubuntu. For users needing only the release number, lsb_release -r displays it directly.

Checking System Files for Version Information

Ubuntu also stores version details in system files. By using the cat command, users can display the contents of these files. Typing cat /etc/lsb-release or cat /etc/os-release in the terminal will reveal comprehensive details such as version ID, pretty name, and version codename. The cat /etc/issue command gives a simpler output showing just the release information.

Reviewing Graphical User Interface Options

Those who prefer a graphical approach can check their Ubuntu version in their system settings. The exact steps may differ based on the Desktop Environment like GNOME or Unity. Typically, users navigate to “Settings” and find a section labeled “Details” or “About” where the Ubuntu version and other related information like architecture and kernel version are listed.
