How to Tell the Version of Ubuntu: Your Definitive Guide
Want to know which flavor of Ubuntu is currently gracing your system? Fear not, intrepid user! Unveiling your Ubuntu version is surprisingly straightforward, and this guide will not only show you how but also equip you with the knowledge to navigate the often-confusing landscape of Ubuntu releases. Simply put, there are several methods to determine your Ubuntu version:
Using the command line: The most reliable method involves opening a terminal and executing the command
lsb_release -a. This will display detailed information, including the release number and codename.Checking
/etc/lsb-release: This file contains key-value pairs that define the Ubuntu release. You can view its contents using a text editor or thecatcommand in the terminal.Using
/etc/os-release: This file is similar to/etc/lsb-releasebut provides more standardized information across different Linux distributions.Via the graphical interface: If you prefer a visual approach, you can typically find the Ubuntu version in the system settings or about section.
These methods work across various Ubuntu versions and desktop environments. Let’s delve deeper into each approach and address common questions you might have.

Command Line Mastery: The lsb_release Command
The lsb_release command is your go-to tool for identifying your Ubuntu version. Open your terminal (usually by pressing Ctrl+Alt+T) and type the following command, then press Enter:
lsb_release -a This command will display output similar to this:
No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 22.04.3 LTS Release: 22.04 Codename: jammy Let’s break down what each line means:
Distributor ID: Clearly identifies the operating system as Ubuntu.
Description: Provides a more descriptive label, including the version number and whether it’s a Long Term Support (LTS) release. LTS releases are supported for a longer period than standard releases.
Release: This is the crucial part – the numerical version number. In this example, it’s 22.04, indicating Ubuntu 22.04.
Codename: Ubuntu versions are also given codenames. This example’s codename is “jammy,” referring to the “Jammy Jellyfish” release.
Examining /etc/lsb-release and /etc/os-release
For a more direct look at the information, you can examine the contents of the /etc/lsb-release and /etc/os-release files. These files use a key-value pair format. To view their contents, use the cat command in the terminal:
cat /etc/lsb-release The output might look like this:
DISTRIB_ID=Ubuntu DISTRIB_RELEASE=22.04 DISTRIB_CODENAME=jammy DISTRIB_DESCRIPTION="Ubuntu 22.04.3 LTS" Similarly, you can view /etc/os-release:
cat /etc/os-release The output of this command is as follows:
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" HOME_URL="https://www.ubuntu.com/" SUPPORT_URL="https://help.ubuntu.com/" BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/" PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy" VERSION_CODENAME=jammy UBUNTU_CODENAME=jammy These files provide a programmatic way to access the Ubuntu version information, which is useful in scripts or applications.
Graphical User Interface (GUI) Methods
If you prefer using the GUI, the exact steps might vary slightly depending on your desktop environment (GNOME, KDE Plasma, XFCE, etc.). However, the general principle remains the same.
- GNOME: Go to Settings (often accessible from the top-right corner menu) and look for an About section. This section usually displays the Ubuntu version, along with other system information.
- KDE Plasma: Navigate to System Settings, then System Information. The Ubuntu version should be listed there.
- XFCE: Go to Settings, then About XFCE. This will display basic system information, including your Ubuntu version.
Frequently Asked Questions (FAQs) about Ubuntu Versions
1. What does “LTS” mean in the Ubuntu version name?
LTS stands for “Long Term Support.” Ubuntu LTS releases are supported for a longer period (typically 5 years for the desktop version and 5 years/10 years for the server version) than standard releases. This means you’ll receive security updates, bug fixes, and hardware enablement updates for the duration of the support period, making it a more stable choice for long-term deployments.
2. What is the difference between LTS and non-LTS releases?
Non-LTS releases are supported for a shorter period, typically 9 months. They often include newer features and software packages, but may also be less stable than LTS releases. Think of LTS as a reliable workhorse and non-LTS as a cutting-edge race car.
3. How do I upgrade to a newer version of Ubuntu?
You can upgrade using the Software Updater tool or via the command line. For example, to upgrade from the terminal, you can use the following commands:
sudo apt update sudo apt upgrade sudo do-release-upgrade Always back up your data before performing a major upgrade!
4. What happens when my Ubuntu version reaches its end of life (EOL)?
When your Ubuntu version reaches EOL, it no longer receives security updates or bug fixes. Continuing to use an EOL version is a security risk. You should upgrade to a supported version as soon as possible.
5. How do I find out the architecture of my Ubuntu system (32-bit or 64-bit)?
You can use the following command in the terminal:
uname -m If the output is x86_64, you have a 64-bit system. If it’s something like i686 or i386, you have a 32-bit system.
6. Can I run a newer version of Ubuntu on older hardware?
It depends. Newer Ubuntu versions might require more resources (CPU, RAM, disk space). While Ubuntu is generally lightweight, older hardware might struggle with the latest releases. Consider using a lightweight desktop environment like XFCE or Lubuntu if you have older hardware.
7. How are Ubuntu version numbers determined?
Ubuntu version numbers are based on the year and month of the release. For example, Ubuntu 22.04 was released in April 2022.
8. What are some popular Ubuntu flavors (besides the standard Ubuntu)?
Ubuntu has several official flavors, each with a different desktop environment:
- Kubuntu: Uses KDE Plasma.
- Xubuntu: Uses XFCE.
- Lubuntu: Uses LXQt (very lightweight).
- Ubuntu MATE: Uses MATE.
- Ubuntu Budgie: Uses Budgie.
- Ubuntu Studio: Optimized for multimedia creation.
9. How can I find out which kernel version I am running?
Use the following command in the terminal:
uname -r This will display the kernel version number. The kernel is the core of the operating system.
10. Is it possible to downgrade to an older version of Ubuntu?
Downgrading is generally not recommended and can be complex and potentially lead to data loss. It’s usually better to perform a clean installation of the older version. Always back up your data before attempting any significant system changes.
11. Where can I find a list of all Ubuntu releases and their support lifecycles?
The official Ubuntu website provides detailed information about all releases and their support status. You can easily find this information by searching for “Ubuntu releases” on your preferred search engine.
12. I’ve tried lsb_release -a and it says “command not found.” What should I do?
This usually means the lsb-release package is not installed. You can install it using the following command:
sudo apt update sudo apt install lsb-release Then, try running lsb_release -a again. The apt package manager is used to install software on Debian-based systems like Ubuntu.
