[Bug 1717404] Re: IPv6 support regresses with nplan transition

[Launchpad Bug Tracker]

This bug was fixed in the package nplan - 0.29

---------------
nplan (0.29) artful; urgency=medium

  * Fix autopkgtests in a world where /run/NetworkManager/conf.d already
    exists. nplan is enabled by default, so it might well have the directory
    already created on the filesystem.

Title:
  IPv6 support regresses with nplan transition

Status in nplan package in Ubuntu:
  Fix Released

Bug description:
  Prior to the switch to nplan, systems (in my case containers) would
  DHCP for IPv4 and let the kernel do IPv6 auto-configuration whenever a
  router advertisement comes in.

  That's the exact same behavior we see on every single other Linux
  distribution, but ever since the switch to nplan by default in Ubuntu,
  we're not getting an IPv6 address anymore when a RA reaches the
  container.

  This was spotted by a new Jenkins test we're running which ensures
  that every single image we have for LXD will start and get a working
  IPv4 (through DHCP) and IPv6 address (through RA).
