mentioning the version of the package you tested and change the tag from
verification-needed-xenial to verification-done-xenial. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-xenial. In either case, details of your

Bug description:
  [Impact]

  Handle SystemExit exception, as those don't propagate past the
  reactor.

  It is hanging forever in environments (installer-chroot) where the
  broker will not start.

  [Test Case]

  To test:

  sudo rm /etc/init.d/landscape-client
  sudo ln -s /bin/echo /etc/init.d/landscape-client
  sudo time landscape-config -a someaccount -t sometitle --silent

  Script should timeout and not run forever. The time it takes to
  timeout unfortunately varies a lot, but is usually between 1 and 3
  minutes.

  [Regression Potential]

  The change restores the same logic which was used before this
  regression, which should be safe.

  As the code change is only used for initialization of the service after calling the configuration tool, regression in this area would force the
  admin to restart the landscape-client service manually after calling landscape-config if that tool is used.

  --- Original description ---

  Ubuntu Xenial installer (ubuntu-16.04.2-server-amd64.iso) doesn't
  offer option to provide http/https proxy to be used by Landscape
  client when selecting "Manage system with Landscape" on upgrades
  management tasksel question.

  Therefore if system is placed behind proxy it will not be able to
  communicate with landscapce server.

  During system installation installer is asking user to provide proxy
  that is used by APT. It would be suitable that same proxy would be
  used for landscape.
