Your issue looks curious, is it still reproducible for you? If yes, could you run your command with the additional "-d" flag to have more details? thanks

It took me some time to realize, but I think that you have a mixup of versions of s3cmd on your system. The line in localy_copy should be like that: for (src_obj, dst1, relative_file, md5) in copy_pairs:

And here you have a previous versions that use only 3 arguments in the tuple.

Please check your setup.

• There is one "s3cmd" file in /usr/bin (that is probably from an older version in your case)
• Library components are in a folder like: /usr/lib/python3/site-packages/S3 (that is probably of a recent version)
