juju bootstrap MAAS 2.0 runtime error

[garyx]

Hi there,

I am trying a fresh install of Xenial MAAS. Packages are as follows.
MAAS 2.0.0~beta3+bzr4941-0ubuntu1
JUJU is beta5 from the devel repository.
I set the correct flag so JUJU can talk to the new 2.0 api in MAAS 2.0

Doing a bootstrap to MAAS fails with a runtime error and here is the debug output as well.

Thanks for the report. We track bugs for Juju in launchpad, so I've opened this bug report for you:

Ahh ofc, my bad. Just ran to github for some reason.
