So, I could have an example setup.py which sets a bugtrack url however using sdist and bdist_wheel on them produces this warning:

H:\Python\Python360\lib\distutils\dist.py:261: UserWarning: Unknown distribution option: 'bugtrack_url'
  warnings.warn(msg)

The issue with this is wanting to set or change the bug track url's for the particular packages using setup.py to generate a PKG-INFO file which explicitly sets the value.

Currently there is no way to modify the fields online anymore since probably like 3~4 months ago I before was able to do it for a little while without having to upload a PKG-INFO file.

Example setup.py that does this:

from setuptools import setup
import re

requirements = []
try:
    with open('requirements.txt') as f:
        requirements = f.read().splitlines()
except Exception as ex:
    with open('sasync.egg-info\requires.txt') as f:
        requirements = f.read().splitlines()

version = '0.0.1'

if not version:
    raise RuntimeError('version is not set')

with open('README') as f:
    readme = f.read()
