This all started with an investigation into Fedora's use of ecua2ools
package. This package is a bit of a nightmare because it pulls in a
lot of other system-python packages.
For Ubuntu, this package was removed in
I47b7e787771683c2fc4404e586f11c1a19aac15c. However, it is not
actually a "pure python" package as described in that change, in that
it is not installable from pypi. I can't see how you could actually
run exercises/euca.sh on Ubuntu unless you installed euca2ools by hand
-- ergo I suggest it is totally unused, because nobody seems to have
reported problems.
In the mean time, ec2 api has moved to a plugin [1] anyway where the
recommendation in their README is to use the aws cli from amazon.
Thus remove all the parts related to EC2 and ecua2ools from base
devstack.
