Dear maintainers,
The ipykernel package fails to build from source in Ubuntu focal, because
Ubuntu has begun the transition to python3.8 and ipykernel 4.9.0 is not
source-compatible with python3.8:

(https://launchpad.net/ubuntu/+source/ipykernel/4.9.0-2/+build/17963855)
Debian has not yet started the transition to python3.8 - the version of
python3-defaults that adds python3.8 as supported is currently in
experimental - but this will eventually become a serious bug in Debian as
well once that transition begins.
For the moment I have worked around the failure in Ubuntu by changing the
packaging to test only against the current version of python3 and not
against all supported versions, but this is a very short-term fix given that
python3.8 will become the default in the next 6 months.
Thanks,
