Please see: wiki on GitHub
| What is AttributeError: 'module' object has no attribute 'format_exc'? |
You are probably using Python 2.3 or older, however s3cmd only supports Python 2.4 or newer.
| What is error 'KeyError: etag'? |
This is an old error in s3cmd that is now fixed. Please upgrade to s3cmd 0.9.8.4 or later.
| Why does s3cmd complain about invalid signature after upgrading from older s3cmd? |
S3cmd 0.9.5 added support for buckets created in European Amazon data center. Unfortunately the change has broken access to existing buckets with upper-case characters in their names. This regression has long stayed unnoticed and has only recently been fixed in s3cmd 0.9.8.4.
Therefore if you are suddenly getting errors like:
ERROR: S3 error: 403 (Forbidden): SignatureDoesNotMatch
after upgrading from s3cmd 0.9.4 or older to 0.9.5 or newer, you are advised to upgrade even further to s3cmd 0.9.8.4 or newer to regain access to your upper-case named buckets.
