[Xenial] 0.9.1~fan1 from ppa:apw/fan-staging fanatic fails if lxd not installed

[Leann Ogasawara]

I was testing fanatic from apw's fan-staging ppa:

ubuntu-fan:
  Installed: 0.9.1~fan1
  Candidate: 0.9.1~fan1
  Version table:
 *** 0.9.1~fan1 0
        500 http://ppa.launchpad.net/apw/fan-staging/ubuntu/ xenial/main amd64 Packages
        100 /var/lib/dpkg/status
     0.9.0 0
        500 http://us.archive.ubuntu.com/ubuntu/ xenial/main amd64 Packages

I didn't have lxd installed when running fanatic and get the following error:

$ sudo fanatic
Welcome to the fanatic fan networking wizard. This will help you set
up an example fan network and optionally configure docker and/or LXD to
use this network. See fanatic(1) for more details.

Hrm, something is not quite right with this test box, I'm going to reimage it. Testing fanatic from ubuntu-fan-0.9.1~fan1 without lxd on another system is not exhibiting this issue. Marking this Invalid while I continue to investigate.
