Description Kevin Howell 2018-11-29 16:21:18 UTC 
Description of problem: As seen in bug 1654126, if an application uses setuptools entrypoints and properly declares a dependency on dbus-python, then it fails to run when dbus-python is installed via RPM. The dbus-python package isn't picked up due to missing the egg metadata.

How reproducible: 100%

Steps to Reproduce: See bug 1654126

Actual results: setuptools entrypoints cannot locate dbus-python when installed via RPM.

Expected results: setuptools entrypoints can locate dbus-python when installed via RPM.

Additional info: We will workaround for now in subscription-manager by removing dbus-python from requires.txt manually, but it seems prudent to fix this anyways.

The bug is also present in RHEL 7.
Comment 2 Till Maas 2019-05-20 19:34:36 UTC 
This was fixed in Fedora Rawhide 3 months ago: https://src.fedoraproject.org/rpms/dbus-python/c/7505b46ea4a52d8ac5cdee35c4725cc5bd808aba?branch=f30

This packaging bug is making it hard for users to install packages from PyPi that require dbus-python because pip3 does cannot recognize that the python3-dbus package provides dbus-python. Therefore it tries to compile  it from source making things unnecessary complicated:


pip3 install nmstate
