Ubuntu – Network settings fail for ubuntu/xenial64 Vagrant box


With the Official Ubuntu 16.04 LTS (Xenial Xerus) Vagrant box image (on VirtualBox) I have problems with basic network settings:

My Vagrantfile:

Vagrant.configure(2) do |config|

  config.vm.box = 'ubuntu/xenial64'

  config.vm.define "xenial" do |server|
    server.vm.network "private_network", ip: ""

vagrant up result:

==> xenial: Configuring and enabling network interfaces...
The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!

/sbin/ifdown eth1 2> /dev/null

Stdout from the command:

Stderr from the command:

sudo: unable to resolve host ubuntu-xenial
mesg: ttyname failed: Inappropriate ioctl for device

Leaving the configuration to DHCP also does not work:

server.vm.network "private_network", type: "dhcp"

At the same time, the above configurations work for ubuntu/trusty64 and ubuntu/wily64 and unofficial gbarbieru/xenial.

Trying the command /sbin/ifdown eth1 2> /dev/null gives no results as the interface has different naming scheme (the main one is enp0s3).

Am I missing something obvious here or is the box just broken?

The problem seems to be solved in the next release of vagrant: https://github.com/mitchellh/vagrant/issues/7155

I tried another box from Jeff Geerling https://twitter.com/geerlingguy/status/723571293174427648?lang=fr and it worked perfectly for me. Jeff has done a lot of great work on Vagrant/Ansible so I guess it's the best solution before the release of the next version of Vagrant
