1. Check Ubuntu Version Using “lsb_release” Command
The lsb_release is a command used to display Linux Standard Base (LSB) and distribution-specific information about the Linux distribution you are using. You can check the Bash version using the lsb_release command along with the release option and -a argument:

4. Check Ubuntu Version from the Issue File
In Linux, the issue file contains information about the operating system release and version. It is typically located in the /etc/ directory. You can write a Bash script that will open this file and show you the version of Ubuntu.

The /etc/os-release file in Ubuntu is a vital source of information about the operating system. It provides a variety of information about the Ubuntu distribution, such as the version, codename, and other crucial characteristics.
cat /etc/os-release
Here you can see that running the Bash script printed information of the os-release file, including the Ubuntu version.
