Comment # 1 on bug 1223538 from Filippo Bonazzi

The networkx python package is just problematic. It was already set as optional
by upstream in the past, then inadvertently turned back to required by upstream
in release 5.6.0. Cathy already reported this:
https://github.com/SELinuxProject/setools/pull/126
and a more general fix was just merged by upstream:
https://github.com/SELinuxProject/setools/pull/128

Not sure how long it will take for upstream to release that fix into a new
version.

Perhaps we can come up with an interim solution like changing the
python3-setools "Require: python3-networkx" into a Suggests (I think that
dependency would be weak enough?) in our own packaging. Let me revisit this
tomorrow
