Actually, a few iterations before, when "service_type was not specified" it did the installation from unstable without any issues. Seems as nondeterministic but that's even more strange right?

Actual code:

resource "null_resource" "hab-svc" {

  depends_on = ["openstack_compute_floatingip_associate_v2.terraform"]

  connection {
    type = "ssh"
    user = "ubuntu"
    host = "${element(openstack_compute_floatingip_v2.management.*.address, count.index)}"
    private_key = "${file("${var.ssh_key_file}")}"
  }

  # upload certificates
  provisioner "local-exec" {
    command = "mkdir ./tmp; cp -v ./cfssl/*vault*.pem ./tmp"
  }
  provisioner "remote-exec" {
    inline = [
      "sudo mkdir -p /hab/svc/etcd/files",
      "sudo mkdir -p /hab/svc/vault/files",

    ]
  }
  provisioner "file" {
    source      = "./tmp/"
    destination = "/hab/svc/etcd/files"
