The armhf cloud image fails during apt-update as the source.list includes a reference to trusty-security, a source that does not appear to host support for that architecture:
http://security.ubuntu.com/ubuntu/dists/trusty-security/

This issue is blocking the use of the armhf version of ubuntu on docker hub's official library:

The latest image possesses with this issue,
but might want to check other image architecture and suites as well:
