Thanks for letting us know. I’m sorry to say I can’t find the detail regarding the python 3 issue. 
If I were to guess though, I suspect the problem is that pyke forked itself and maintains two branches 
for its python 2 -> python 3 journey (don’t know why one would choose to do that). 

As a result, pyke for python 3 needs to come from a different source. 
To see how to work around that, the conda-forge build for this is done in 

https://github.com/conda-forge/pyke-feedstock/blob/master/recipe/meta.yaml#L12.

Hopefully my guess is on target, but if not, 
could you point me at the detail and I’ll try to help?

Thank you for the information that there is a separate source for python3.

I am now trying to make a python3-pyke package.

Iris 2.2.1 has landed in our ppa.

python3-pyke has also been created, but python3-iris fails to build.
