Ubuntu, a popular Linux distribution, undergoes regular updates and releases. Knowing the version of Ubuntu you’re running can be crucial for various reasons, such as software compatibility, troubleshooting, or when seeking support.
In this guide, we will walk you through the steps to check the version of Ubuntu installed on your system. By the end of this tutorial, you’ll be able to determine not only the version number but also the codename and release date of your Ubuntu installation.
Checking the version on your system can be done using the terminal. Follow these simple steps to check the Ubuntu version:
Open the Terminal
Open the terminal by pressing Ctrl + Alt + T or by searching for “terminal” in the application menu.
Check Ubuntu Version:
Using the “lsb_release” Command
Enter the following command in the terminal:
lsb_release -a
This command stands for “Linux Standard Base” and provides information about the Linux distribution. It will display detailed information about your Ubuntu version, including the distribution, release number, and codename. The output should look similar to this:
No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 18.04.6 LTS Release: 18.04 Codename: bionic
From the above output, you can determine that the Ubuntu version is “18.04.6 LTS” and the codename for this release is “bionic”.
Alternatively, you can use the following command to display only the Ubuntu release number:
lsb_release -r
The output will be similar to this:
Release: 18.04
Using the “/etc/os-release” File
Type the following command:
cat /etc/os-release
The output will display various details about your Ubuntu system, including the version. Look for the lines starting with PRETTY_NAME or VERSION.
root@geeks:~# cat /etc/os-release NAME="Ubuntu" VERSION="18.04.6 LTS (Bionic Beaver)" ID=ubuntu ID_LIKE=debian PRETTY_NAME="Ubuntu 18.04.6 LTS" VERSION_ID="18.04" 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=bionic UBUNTU_CODENAME=bionic
Using the “/etc/lsb-release” File
Enter the Command:
cat /etc/lsb-release
This file specifically contains information about the Ubuntu version. Look for the line starting with DISTRIB_DESCRIPTION.
root@geeks:~# cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=18.04 DISTRIB_CODENAME=bionic DISTRIB_DESCRIPTION="Ubuntu 18.04.6 LTS"
Using the “hostnamectl” Command
Enter the Command:
hostnamectl
This command provides information about the system’s hostname and other related details, including the Operating System. Look for the line starting with Operating System.
root@geeks:~# hostnamectl
Static hostname: ubuntu.webhostinggeeks.com
Icon name: computer-vm
Chassis: vm
Machine ID: c9bfbfda64dd452d80996bb647adb33a
