You had to manually edit the sudoers file on drbl server:
visudo /etc/sudoers
Append the account in it. Take account "john" as an example: 
john        ALL=(ALL) ALL
Then run "drblpush -i".
BTW, on Ubuntu Linux, the root account is not really usable (i.e. you can not login on console) until you assign it a password on the server. The default is no password.
Thanks to lophat at users.sourceforge.net for providing this hint.
