I just checked this happens up to artful but I wonder.
Is anybody using the 2.0 at all?
I mean it fails right away.

There is also the non 2.0 agent in /usr/sbin/waagent
Is that what people use?

Do they use the packaged version at all or something that is bundled in the image build process?

There are too many uncertainties that at least I don't understand.
I'm subscribing Dan for his experience around the cloud and cloud image handling.

@Dan - do you know how this is supposed to work and who maintains it usually - I saw some uploads from foundations, but thought you'd be the best start to sort it out?

waagent is used at boot; it may use Python's internal import mechanism
to pull in waagent2.0, but I don't believe it ever does that (else we'd
see this during normal operation, which we don't).

I think the problem is that waagent2.0 is installed with a shebang that
points at Python 3; it is written only to work with Python 2.
