check debian version

Knowing how to check Debian version on your server is more than just a simple trick.

Version numbers are important because developers release applications and security patches that target specific Debian versions.

In many cases, you need to be very sure about the version of the Debian OS installed on a machine when using it as a foundation for your business application stack. To ensure everything is working correctly, you need to match the applications’ versions with the Debian versions installed on the server.

This removes the problems caused by incompatible versions and missing dependencies.

In all cases, before diving into server management, it is always a good idea to check Debian version right after logging into the server.

This article will cover the ways you can check Debian version installed on a machine. We’ll cover both the command line and graphical user interface methods. But first, let’s learn a bit more about Debian versions.

Understanding Debian Versions

It is important to know the version of your Debian Linux system, as new versions are typically updated every two years. As mentioned earlier, keeping current with the updates can help maintain security and access the latest software.

Debian offers at least three releases in active maintenance: stable, testing, and unstable.

Stable

The most recent version of Debian is called Stable. At the time of writing this piece, version 11 is the most current and highly recommended by Debian. It is codenamed the Bullseye. It was initially released as version 11.0 on August 14th, 2021, and its latest update, version 11.6, was released on December 17th, 2022.

Testing

The Testing distribution contains packages that haven’t been accepted into the Stable version, but are in the queue for compatibility testing. The Testing version has many advantages, as it comes with recent versions of integrated software.

Unstable

The Unstable version is the distribution that’s always under active development. This distribution is used by developers who wish to live on the edge. However, we don’t recommend it for production and live environments.

How to Check Debian Version Installed on Your Machine?

There are several methods to determine which Debian version is currently active on a server. Version numbers and code names can indicate the age of a version.

Let’s dive into the methods.

Method # 1: Use hostnamectl

To view the version of your Debian operating system, you can use the hostnamectl command, which is a tool included with systemd. The output may display either the version number or the code name for the particular release.

# hostnamectl

hostnamectl method

Method # 2: View the /etc/issue File

Another way to see this information is by viewing the /etc/issue file. Use the cat command to check the contents of the /etc/issue file.

# cat /etc/issue

# cat /etc/issue

Method # 3: Check the /etc/os-release File

The /etc/os-release file displays the operating system version number and code name.

# cat /etc/os-release

# cat /etc/os-release

Method # 4: Use the lsb_release Command

The version number can be determined by running the lsb_release command with the “-r” option.

This simple utility shows Linux Standard Basic (LSB) information about the Linux distribution. It is the recommended way to check the Debian version.
For example, the following command on Debian can be used to obtain the version number:

# lsb_release -crid

metho4 lsb release

Method # 5: Use the GUI to Check the Debian Version

If you don’t want to use the terminal, check your Debian version using a graphical interface. To do this, you must install the Hardinfo utility (if you don’t already have it on your system). For this, use the following code in the terminal:

# apt-get install hardinfo

When you launch the program, you can see your current Debian version in “Operating system” under “Computer.”
