User is not in the sudoers file. This incident will be reported On using the sudo command if we see the error User is not in the sudoers file. This incident will be reported This means that the user as whom we have logged in and are trying to run the command "sudo" does not have the permission to do so. Only the users listed in /etc/sudoers have the permission to use the command "sudo". To give the sudo permission to a user we need to add the user to the file /etc/sudoers file. Open the file /etc/sudoers as root.
sudo vi /etc/sudoers
