Ubuntu LTS version in tutorial text does not match version displayed in terminal

[aritrakoley]

The tutorial text says that the version should be displayed as 18.04.3 upon running cat /etc/issue command but in reality it is displayed as 20.04.3

hey Aritra! thx for reporting this.

Since the guides are publicly editable, would you like to send a PR to improve it?

I've made a PR for it. (#231)

( I'm very new to open source contributions so please let me know if I need to take any additional steps )
