Todos los comandos de sudo en Ubuntu para ser administrador
By default, only the user who installed the system is permitted to run sudo. To add more
administrators, i. e. users who can run sudo, you have to add these users to the group
'admin' by doing one of the following steps:
* In a shell, do
sudo adduser username admin
* Use the graphical "Users & Groups" program in the "System settings" menu to add the new
user to the admin group.
