twine upload to pypi with --skip-existing not working

[lwanger]

I am unable to upload a universal wheel to the pypi server. When I do so I get the message:

$ twine upload --skip-existing dist/cooked_input-0.2.5-py2.py3-none-any.whl
Uploading distributions to https://upload.pypi.org/legacy/
Skipping cooked_input-0.2.5-py2.py3-none-any.whl because it appears to already exist

I can upload if I bump up the version number and release a new distribution.

My ~/.pypirc is (password blotted out for obvious reasons):

[distutils]
index-servers=
pypi
testpypi

[pypi]
username = lwanger
password = ********

[testpypi]
repository = https://test.pypi.org/legacy/
username = lwanger
password = ********

My twine version is:

$ twine --version
twine version 1.9.1 (pkginfo: 1.4.1, requests: 2.18.4, setuptools: 36.2.7,
requests-toolbelt: 0.8.0, tqdm: 4.15.0)

I am running Python 3.6.1 on Windows 10

Hi @lwanger, it appears that the distribution cooked_input-0.2.5-py2.py3-none-any.whl already exists here: https://pypi.org/project/cooked-input/0.2.5/#files, therefore PyPI will not let you re-upload it. See pypa/packaging-problems#74.

By adding the --skip-existing flag to the twine command, you are telling twine to not fail if a given distribution already exists on PyPI.

I'm going to close this as it doesn't seem to be an issue with Warehouse, but please feel free to comment here if you have additional questions.
