[Bug 1339518] Re: sudo config file specifies group "admin" that doesn't exist in system

[Marc Deslauriers]

Older releases of Ubuntu used a group called "admin" instead of "sudo"
which is the name Debian chose later on.

We need to maintain the "admin" group rights in our sudoers file for
people upgrading from earlier Ubuntu releases. If we remove it, they
will no longer have sudo rights after upgrading.

Title:
  sudo config file specifies group "admin" that doesn't exist in system

Status in sudo package in Ubuntu:
  Confirmed

Bug description:
  
  In the configuration file for sudo ( /etc/sudoers ) you find this section:

  # Members of the admin group may gain root privileges
  %admin ALL=(ALL) ALL

  # Allow members of group sudo to execute any command
  %sudo   ALL=(ALL:ALL) ALL

  The sudo group is in /etc/group, but not admin group. This is a
  cosmetic bug, but if we specify a group that are allowed to use sudo
  command, then the group should exist in the system too.

  Installed version: Ubuntu 14.04 LTS all upgrades up to 9 july 2014
  installed, 64 bit desktop ISO used for installation.

  Sudo package installed:
  ii  sudo                        1.8.9p5-1ubuntu1   amd64              Provide limited super user privileges to specific users
