[Bug 1507247] Re: avahi-daemon dies after about a minute

Tue Sep 24 03:42:29 UTC 2019

I actually have a fix for this. The reason why the daemon is dying is
because dbus is disabled in avahi and the configuration expects DBUS to
be enabled for status checking. Make sure you have "enable-dbus=yes" in
avahi-daemon.conf :)

Title:
  avahi-daemon dies after about a minute

Status in avahi package in Ubuntu:
  Fix Committed

Bug description:
  So I thought I'd try running Vagrant inside of an Ubuntu VM to do some
  development work as detailed here:
  http://taoofmac.com/space/HOWTO/Vagrant

  When the box starts up, there is a short delay before broadcasting
  begins, and I'm able to ping the guest (in this case registered as
  "hobo-container.local").

  Then, after a minute or two, it stops responding.  The logs look like
  this:

  So it looks like it's starting again, waiting for about a minute, and
  then dying again.  Testing bears this out. When I issue the start, I'm
  able to ping the guest by its avahi-broadcasted hostname again until
  the process dies.

  Interestingly, if I merely run avahi-daemon as root, the process stays
  running and doesn't die. It's been going strong for 10 minutes now
  with no change in ouput from

  `watch ping -o hobo-container.local` from the host machine.
