I have a package called fbs on PyPI. Every once in a while, I get the following error while trying to upload a new version with twine:

HTTPError: 400 Client Error: This filename has already been used, use a different version. See https://pypi.org/help/#file-name-reuse for url: https://upload.pypi.org/legacy/

The error occurs even though I have never uploaded the respective version before. To work around it, I have to use a different version number.

What's curious: The version numbers for which this happens exhibit a strange pattern. The problem has so far occurred for versions 0.2.1, 0.2.2, 0.2.3, 0.3.1, 0.3.2 and 0.3.3. Notice the pattern .1, .2, .3. But probably it's coincidence.

Out of curiosity, I tried pip install for one of the versions which PyPI claims already exist. (Eg. pip install fbs==0.3.1.) But I got

No matching distribution found for fbs==0.3.1

My suspicion is that someone else had control of this package on PyPI before me, then deleted it. This left over some "old" releases, which now conflict with my new ones. If PyPI lets you delete packages, then I believe it should also clean up any old files so future owners of that package can use it as if it were new.

I'm using twine 1.12.1 and the following commands for uploading:

python setup.py sdist
twine upload dist/fbs-x.y.z.tar.gz

twine upload --verbose dist/fbs-0.3.1.tar.gz gave:

I'm on Ubuntu Linux 16.04 with Python 3.5.3, in case that's relevant.

Thanks!

Looks like this is related to pypa/packaging-problems/issues/74. But it's also somewhat different in that the scenario there is to re-upload after deleting a file. The present issue is likely about re-uploading after deleting the entire package.

Also seems like what I'm experiencing is pypa/packaging-problems/issues/188. Except that there, the owner deleted the package himself. I seem to have unknowingly inherited a package from a previous author.

@mherrmann You are correct, the fbs project has deleted releases from a previous owner. You can see the list of all actions done to the project, including which files/versions have already been uploaded at https://pypi.org/manage/project/fbs/history/.

This is essentially a duplicate of #4440, which proposes to fix this confusion by "soft" deleting projects, releases and files, and having them persist across ownership changes. As such, I'm going to close this issue, but thanks for the report!
