How to Add User to Sudoers in Ubuntu
https://linuxize.com/post/how-to-add-user-to-sudoers-in-ubuntu/
To add the user to the group run the command below as root or another sudo user. Make sure you change “username” with the name of the user that you want to grant permissions to.
usermod -aG sudo username
Copy
Granting sudo access using this method is sufficient for most use cases.
To ensure that the user has sudo privileges, run the whoami command:
sudo whoami
Copy
You will be prompted to enter the password. If the user has sudo access, the command will print “root”:
