General summary/comments (optional)

On Ubuntu Yakkety (16.10) the libvirtd group was renamed to libvirt. During the transition there are both group entries with the same gid in /etc/groups. See "In more recent releases (>= Yakkety) the group was renamed to libvirt. Upgraded systems get a new libvirt group with the same gid as the libvirtd group to match that."

$ cat /etc/group | grep 142

This causes stack to issue the same two groupadd commands in a row (use --verbose to see).

Steps to reproduce

  1. Install libvirt on ubuntu 16.10
  2. Add yourself to the libvirt or libvirtd group
  3. Log out & log in or issue newgrp libvirt in a terminal
  4. Run command stack --docker build


It should work


It fails with duplicate groupadd commands and exits code 9
