-At present (May 2020), all these base VM images are built from Ubuntu
-xenial, and launchpad-buildd runs on Python 2.  We plan to upgrade these to
-bionic soon, where it will be possible for launchpad-buildd to run on Python
-3; however, it's necessary to support the powerpc architecture until at
-least April 2021 (end of standard maintenance for xenial), and the powerpc
-base images will need to stay on xenial since that architecture is no longer
-supported by bionic.  As a result, launchpad-buildd must run on both Python
-2 and 3 for the time being.
