2 ways to add users to SUDOERS group in Debian

The SUDOERS group plays a vital role in Debian Linux, granting administrative rights to users. Adding users to the SUDOERS group enables them to execute commands with root privileges, providing them with the necessary administrative access to perform various tasks on Debian systems.

During the installation of Debian Linux, if you leave the password of the root account blank, then the first user created in the system will have the administrative permissions. However, if you set a root password, the username will not have sudo permissions. Therefore, you may encounter errors similar to the following while using the user account to perform administrative tasks.

<username> is not in the sudoers file. This incident will be reported.
