After trying to upload a package on Pypi website using
python setup.py sdist upload
I got this error message:
Submitting dist/XXX-0.7.5.tar.gz to https://upload.pypi.org/legacy/ Upload failed (403): Invalid or non-existent authentication information. error: Upload failed (403): Invalid or non-existent authentication information.
Despite having registered and succesfully uploaded package before. What happened is that I updated my account on Pypi website by changing the password. So, in such case, just update your .pypirc file, which can be found in your home directory.
[distutils] index-servers = pypi [pypi] username: blabla password: blabla
