[Bug 1675721] Re: nplan autopkgtests very unstable on amd64/i386 (AssertionError: timed out waiting for NetworkManager to settle down)

[Mathieu Trudel-Lapierre]

nplan (0.20) zesty; urgency=medium

  * tests/integration.py: increase timeout for integration tests (networkd and
    NetworkManager "wait-online" checks) to account for longer bring-up times
    when dealing with stacked virtual devices.

Title:
  nplan autopkgtests very unstable on amd64/i386 (AssertionError: timed
  out waiting for NetworkManager to settle down)

Status in nplan package in Ubuntu:
  Fix Released

Bug description:
  Take a look at

    http://autopkgtest.ubuntu.com/packages/n/nplan/zesty/i386

  and

    http://autopkgtest.ubuntu.com/packages/n/nplan/zesty/amd64

  nplan's tests are very unstable (doesn't happen on the other arches
  due to lack of isolation-machine support there). There seems to be a
  couple of common failures

  ======================================================================
  FAIL: test_manual_addresses (__main__.TestNetworkManager)
