In my case this issue appears related to the mtu set on the containers. i'm using juju 1.24.5

When the physical network mtu is 1500 we need to decrease the instance mtu due to the additional GRE header added when using a neutron network encapsulated with GRE.

we can change the default instance mtu to 1454 with ' juju set neutron-gateway instance-mtu=1454'

This makes the openstack instance mtu is 1454 but the juju-trusty-lxc-template created on that instance still has mtu 1500 causing apt-get update to hang during cloud-init.

can we set the default mtu for containers created by juju?
