[Duplicity-talk] boto3+s3 backend with Wasabi storage buckets

[devel]

Hey peeps,


So I am trying to connect to a wasabi s3 compatible bucket using the
boto3 backend but failing.


The command I use is this.

` AWS_ACCESS_KEY_ID="$Wasabi_access_key"
AWS_SECRET_ACCESS_KEY="$Wasabi_secret_key" duplicity full -v9  
--progress    /home 
"boto3+s3://bucketname.s3.eu-central-1.wasabisys.com/folder"`


but the error I keep getting is this:


    Using temporary directory /tmp/duplicity-z9l3i_y8-tempdir
    Traceback (innermost last):
      File "/usr/bin/duplicity", line 106, in <module>

        raise error_class(parsed_response, operation_name)
     botocore.exceptions.ClientError: An error occurred (403) when
    calling the HeadBucket operation: Forbidden



For reference, using the same credentials and command just replacing the
backend with s3://user:key@s3.eu-central-1.wasabisys.com/folder works
fine. But obviously boto2 is deprecated and I should be using boto3.

I am kinda new to this s3 storage paradigm so I am not sure if the error
is my url as given or the servers side. I know Wasabi do support boto3
it is listed here:

So it should just work shouldn't it?

Any assistance is greatly appreciated
