sudo usermod -aG sudo username
For instance, if I wish to add a user named “itechguide”, below is what the command should look like.
sudo usermod -aG sudo itechguide
Also, note that characters won’t be visible while typing your password in the Ubuntu terminal.
- After doing all that, you can confirm if the user has been added to the sudo group by executing the command below. However, replace “username” with the username of the user.
id username
For this demonstration, the username of the user is “itechguide”. So, below is what the command should look like.
id itechguide
- After running the prior command, the output should include “27(sudo)”, indicating the user has been added to the sudo group.

- In the Ubuntu terminal, type the following command and press the enter key. However, replace “username” with the username of the user you wish to add to sudoers.
sudo gpasswd -a username sudo
For example, if I want to add a user with a username of “John” to the sudoers, below is what the command should look like.
sudo gpasswd -a john sudo
- By doing that, you will be prompted to input your password – do so and press the enter key on your keyboard. Hence, the user should be added to sudo group.
