Debian11 administrator is not in the sudoers file

If the administrator is not in the sudoers file on Debian 11, they will not have the necessary privileges to run commands with elevated privileges using sudo. In order to add the administrator to the sudoers file, you will need to have root access or be able to log in as a user with root privileges.

Here are the steps to add the administrator to the sudoers file:

1. Log in as root or a user with root privileges.
2. Open a terminal or command prompt.
3. Run the following command to edit the sudoers file using the visudo command:

visudo

4. This will open the sudoers file in a text editor. Look for a line that says "# User privilege specification" or "# Allow members of group sudo to execute any command" section.
5. Below that line, add a new line with the following syntax:

username   ALL=(ALL:ALL) ALL

Replace "username" with the actual username of the administrator.
6. Save the file and exit the text editor.

After adding the administrator to the sudoers file, they should be able to use sudo to run commands with elevated privileges. Make sure to verify the changes by testing sudo access before relying on it for administrative tasks.
