Error "unsupported operand type(s) for -: 'tuple' and 'float'" when uploading

[jskeet]

This is in a release build which has worked many times today - then failed for the last 6 builds. My guess is that an initial request failed, causing it to trigger some retry code which is broken. All builds are failing with this error:

This looks like an error introduced by a new addition to the auth library. Working on rolling back that change with a new release.

Thank you for filing this!

A new version of google-auth-library-python has been released.
