Subject: [PATCH] Revert back to 16.04 dockerfile temporarily The 18.04
 dockerfile is missing some required tooling necessary to build the debian
 images packages. This tooling is installed in the 16.04 dockerfile, but it
 appears that the same attempts to install this in 18.04 fail. Until this is
 resolved, avoid using the 18.04 image.
