sudo breakage in natty

[Lorenzo De Liso]

Hello,

Yesterday I uploaded a merge of the sudo package (1.7.4p4-5ubuntu1), it
caused the removal of %admin from /etc/sudoers [1]. This resulted in the
impossibility to use the root privileges from the user account(s) added
to that group. Precisely, the problem occurs when the upgrade prompts
for the conffile update and the answer is "Y". If you answered "Y", you
can workaround the problem adding the line "%admin ALL=(ALL) ALL" to
your /etc/sudoers or /etc/sudoers.d/admin directly. Seems like that part
is added from the user-setup package (IIUC). The problem has been
temporarily fixed with a workaround in the version 1.7.4p4-5ubuntu2.

Sorry for the inconvenience.
