MaaS 1.9.5 fails to download Ubuntu 14.04

[Zack Williams]

From a system set up yesterday - Is the upstream image for Ubuntu 14.04 broken? On a working system, there is usually one snapshot directory. 

/var/lib/maas/boot-resources$ ls
cache                     snapshot-20170829-080223  snapshot-20170829-094723  snapshot-20170829-113223  snapshot-20170829-131737
