Problem description
Trying to upload a package licensed under WTFPL to pypi with python3 -m twine upload dist/* I am getting the error message
Invalid value for classifiers. Error: Classifier 'License :: WTFPL' is not a valid classifier.
I have specified the license in setup.cfg as:
classifiers =
Programming Language :: Python :: 3
License :: WTFPL
Operating System :: OS Independent
I have not seen any limitation for the allowed licenses on Packaging Python Projects and the setuptools help for the license field.
It does, of course, make a lot of sense to not allow any string to avoid different names for the same license but I am missing the information which values I can use.
I have somehow found this link which seems to provide the list I am searching for but it does not list the WTFPL. Is it a deliberate decision that some licenses are not allowed or has this license just never been considered? How should users deal with that if the license they want to use is not allowed?
