Thanks for your answer.

I was pretty sure I had already set the token way of enabling upload, nonetheless I went ahead and created a new token for that specific package.

As per the documentation (https://twine.readthedocs.io/en/stable/index.html#twine-upload) I'm setting the environment variables (https://app.travis-ci.com/github/blockchain-certificates/cert-schema/builds/270618825#L180) TWINE_USERNAME to token and the TWINE_PASSWORD to the token value.

However the issue remains (https://app.travis-ci.com/github/blockchain-certificates/cert-schema/builds/270618825#L830).

My last automated release was in March this year so the only thing I thought had changed is that keyring is now on version 25.x. However fixing the version to 24.3.1 (https://app.travis-ci.com/github/blockchain-certificates/cert-schema/builds/270618825#L273) does not seem to solve the issue.

I don't want to create unnecessary noise on this repo if it's not the culprit, so in your opinion is the problem with Twine, Travis or Keyring (or the three of them)?

Thanks again

PS: I've manually published to the newer version as I need to move forward on other front but I still would like to fix the automated release issue.
