I'm trying to add a new user with administrative privileges in Ubuntu, but I'm running into some issues. I followed the typical steps to edit the sudoers file using visudo, but I'm still getting permission errors when the user tries to run sudo commands. I double-checked the syntax, and everything seems correct.

For reference, I found a detailed guide on this process in a blog about managing user permissions in Ubuntu. The guide suggests using usermod and visudo, which is what I did. However, the new user still doesn't have sudo privileges.

Has anyone encountered this issue before? What could I be missing? Any insights would be greatly appreciated!

Thanks in advance!
