How to check Ubuntu version

To check the version of Ubuntu you’re running, you can use one of the following commands:

1. Using lsb_release command

This is the standard way:

lsb_release -a

Output example:

yamlCopy codeNo LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 22.04 LTS
Release:        22.04
Codename:       jammy

2. Using /etc/os-release file

This file contains information about your operating system:

cat /etc/os-release

Output example:

makefileCopy codeNAME="Ubuntu"
VERSION="22.04 LTS (Jammy Jellyfish)"
ID=ubuntu
ID_LIKE=debian
VERSION_ID="22.04"

3. Using hostnamectl

This command provides additional system information:

hostnamectl

Output example:

Operating System: Ubuntu 22.04 LTS
Kernel: Linux 5.15.0-76-generic

4. Using uname (for kernel version)

If you just need the kernel version:

uname -r

Output example:

5.15.0-76-generic

Choose any method based on your preference!
