!!! switch account from <username> to root

=>            "#%sudo ALL=(ALL:ALL) ALL"

Use visudo, append line below. (update the username)

<username> ALL=(ALL) NOPASSWD:ALL

#### /etc/sudoers
- All lines starting with # are comments

- root ALL=(ALL:ALL) ALL – this line means that the root user has unlimited privileges and can run any command on the system

- %admin ALL=(ALL) ALL – the % sign specifies a group. Anyone in the admin group has the same privileges as of root user

- %sudo ALL=(ALL:ALL) ALL – all users in the sudo group have the privileges to run any command
