to Check Which Version is Running on Ubuntu?

We can check the installed version in Ubuntu 22.04 distribution by using two different methods:

Check Ubuntu Version via lsb_release Command

Press the Ctrl+Alt+t’ keyboard shortcut to open the Terminal. Or you can open it by clicking on the terminal icon.

The ‘lsb_relaese’ is a command-line utility that prints the LSB (Linux Standard Base) information about Ubuntu or any other Linux distribution. Most users prefer this method to check the Ubuntu version because it displays the installed version of any Linux distribution no matter which Ubuntu version is running on your system.

Run the ‘lsb_release’ command along with the option ‘-a’ to check which Ubuntu version is currently running on your system:

$ lsb_release -a

The installed Ubuntu version will display in the description. As you can see, Ubuntu 22.04 version is installed on this system. If you want to see only the installed version description in a line instead of displaying all other details, you can use the ‘lsb_release’ command with option ‘-d’:

$ lsb_release -d

Now, the Ubuntu version will show in a description line.

The ‘/etc/os-release’ file contains the information about operating system identification. You can locate this file on the Ubuntu 16.04 or the latest Ubuntu versions of those running systemd services. To check the Ubuntu 22.04 version using the ‘/etc/os-release’ file, run the ‘cat’ command:
