      Exception: Versioning for this project requires either an sdist
  tarball, or access to an upstream git repository. It's also possible
  that there is a mismatch between the package name in setup.cfg and the
  argument given to pbr.version.VersionInfo. Project name python-
  magnumclient was given, but was not able to be found.

  [Regression Potential]
  Changes are required to debian/control and debian/rules to drop py2 support. To help mitigate any regression potential, I've visual inspected builds to compare files included in .deb files. The files match up exactly between the last known-good build ( https://launchpadlibrarian.net/472650057/buildlog_ubuntu-focal-amd64.python-magnumclient_2.11.0-0ubuntu4_BUILDING.txt.gz ) and the new package version that I'm uploading right now.
