[Python-modules-team] Bug#849220: ipykernel: FTBFS (failing tests)

[Santiago Vila]

Package: src:ipykernel
Version: 4.5.2-1
Severity: serious

Dear maintainer:

I tried to build this package in stretch with "dpkg-buildpackage -A"
(which is what the "Arch: all" autobuilder would do to build it)
but it failed:

This is just how the build ends. For a full build log please see:

https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/ipykernel.html

where it also fails in a similar way.

Thanks.
