I am attempting to use the Ubuntu Openstack Multi-install Openstack installer, which in the background runs the `JUJU_HOME=/home/user/.cloud-install/juju juju bootstrap --to machine.maas`. This command works fine on trusty, however when I set `default-series: vivid` in the juju/environments.yaml file and then run the bootstrap command, it results in the following: http://paste.ubuntu.com/11436902/ and then hangs until it receives an ssh connection timeout. If I manually reboot the machine which is being bootstrapped then the command continues. It seems something is going wrong with the SSH service on initial bootstrap that is corrected by a reboot.
I think this issue is a duplicate of one or more issues already fixed in 1.24.x 1.24-beta5 is the current beta and next week will will release a beta6 six that fixes several vivid issues including vivid containers. Can you confirm this is an issue still happens with the betas?
