Comment 2 for bug 1756040

I'll note that I tried just launching a bionic container using snap
3.0.0.beta5 and after "lxc launch ubuntu:x" and "lxc launch ubuntu-daily:b"
neither of them came up with an IP address.

I might have broken my networking on this machine because I was trying to
install stock Juju which tries to bring in stock lxd, ignoring the snap,
but I'm also seeing failures for containers to get IP addresses.
