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

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.

During the OSGeo Virtual Code Sprint we decided: we will try to package py3 version (pike etc), else we will include as py2 in VM. e-mail to project to ask about 20.04
