Package: src:python-tackerclient
Version: 0.11.0-4
Severity: serious
Tags: ftbfs

Dear maintainer:

I tried to build this package in buster with "dpkg-buildpackage -A"
but it failed:

The above is how the build ends in my autobuilder and it's not
necessarily the relevant part.

The failure is not, however, related to using dpkg-buildpackage -A,
as it also fails in reproducible builds:

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

If this is really a bug in one of the build-depends, please use reassign and affects,
so that this is still visible in the page for this package.

Thanks.
