In Unix/Linux systems, the root user account is the super user account, and it can therefore be used to do anything and everything achievable on the system.
Besides security concerns, access to root privilege is necessary when it’s required to perform system maintenance. The sudo command does exactly that. It grants a command/script root privilege as long as it is executed. Users having access to the sudo command are managed by the sudoers file.
However, this can be very dangerous in so many ways, one could be that the root user might enter a wrong command and breaks the whole system or an attacker gets access to root user account and takes control of the whole system and who knows what he/she can possibly do.
In order to perform crucial tasks on your system such as viewing or altering important system files, or updating the system, you need the sudo command to gain super user privileges.
THE ERROR

username is not in the sudoers file. This incident will be reported.
FIXING THE ERROR
This is a very common error for the beginners. The error occurs because we are trying to access/update something with super privileges from the user instead of root -user.
Hence, to solve this, we need to make changes in the sudoers file where the root user has been given the privileges. So, switch to root user, run the following command below.
Step 1: Open Terminal.
Step 2: Let’s try the first command and Enter root password.
==>> sudo su
Step 3: To give the sudo permission to a user we need to add the user to the file /etc/sudoers file.
==>> nano /etc/sudoers
Step 5: Now scroll down to the bottom where you will see this line.
==>> root ALL=(ALL:ALL) ALL
Step 6: Add the same line but replace the username with your username, in my case my username is softxos.
==>> username ALL=(ALL:ALL) ALL
Step 7: After that Press CTRL + x
Step 8: Press Y
Step 9: Hit Enter to Save the file.
Step 10: Exit and switch back to the user and start using sudo commands with ease.
==>> exit
In some cases, you may need to reboot your operating system to work properly.
As you can see, try running a sudo command as the user and the issue is resolved.
That's all, I hope this helps.
