Solution to missing visudo command in Bash

If you receive the error message bash: visudo: command not found when trying to run the visudo command in a Linux shell, it indicates that the sudo package is not installed. This error can be resolved by running the following command

$ apt update 
$ apt install sudo

These commands first update the system package list ( apt update) and then install the sudo package ( apt install sudo). This will make sudo related commands available, including the visudo command.
