Luck!

Set up new user on the ubuntu.

Add new user:

sudo useradd ubuntu -m -s /bin/bash

Add new group:

# sudo addgroup admin

Add user to group:

# sudo adduser <username> <groupname>

in our case:

# sudo adduser ubuntu admin

Make ubuntu sudoers without password:

 # sudo vi /etc/sudoers

Set up

%admin ALL=NOPASSWD: ALL 

for %admin group.

Check:

#sudo su ubuntu 

sudo ls -ls //should not need password

Good luck!
