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

[Trent Lloyd]

Subscribing Marc as he seems to be largely maintaining this and made the
original changes and has been keeping the delta. Hopefully he can
provide some insight.

Seems this is a delta to Debian that is being kept intentionally for a
long time, it's frequently in the changelog even in the most recent
Debian merge.

I'd have thought if we kept this in here by default we probably should
have kept a default 'admin' group with no members but it's a bit late
for that at this point.

- debian/sudoers:
 + also grant admin group sudo access

Also seems this change was originally made in 2014:

sudo (1.8.9p5-1ubuntu3) vivid; urgency=medium

  * debian/patches/also_check_sudo_group.diff: also check the sudo group
    in plugins/sudoers/sudoers.c to create the admin flag file. Leave the
    admin group check for backwards compatibility. (LP: #1387347)

sudo (1.8.9p5-1ubuntu2) utopic; urgency=medium

  * debian/sudo_root.8: mention sudo group instead of deprecated group
    admin (LP: #1130643)

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
