Comment 24 for bug 1685782

If the paste is correctly indented the space constraint is on "1", not "1/lxd/0" (although it is an UX error that it's printed after containers).

I've just tried to reproduce it by doing:
juju add-machine --constraints "spaces=foobar" -> results in "1"
juju add-machine lxd:1

The result is:
1 started 54.229.137.144 i-0e1dae1b16cf14da2 xenial eu-west-1a running
1/lxd/0 started 10.0.215.241 juju-703836-1-lxd-0 xenial Container started

Before the fix from PR7433 the container would never go past 'pending'.

Could you make sure that all controllers are upgraded to the newest version and that this is a version with this PR included? Could you also provide exact steps, maybe there's some small detail that I'm overlooking.
