Expectation:
fakeroot ./debian/rules tests
from ubiquity 17.04.1 package, from zesty-proposed to build successfully.
It does in zesty-release. It does in zesty-proposed too, if one downgrades: libgl1-mesa-glx libglapi-mesa
If one uses libgl1-mesa-glx libglapi-mesa from zesty-proposed, the Xvfb fails to spawn and thus tests fail, and the build fails.
