backup to amazon s3 difficulty

Hello

I am trying to use Deja Dup to backup to Amazon S3. I have set up an Amazon Web Services account, obtained my
Access key ID and Secret access key, and created a bucket. The backup fails, however (please see below). There appears to be an access denied problem. I am, however, confident that I am using the correct Access key ID and Secret access key (I down loaded them upon creation) and I have checked that the bucket works fine (I can upload a file using the AWS console). I have tried with buckets in the US Standard location and EU locations of Ireland and Frankfurt, all to no avail.

I am using Ubuntu 15.04, Deja Dup 32.0-0ubuntu5 and Duplicity 0.7.05-0ubuntu0ppa1130~ubuntu15.04.1 (the latter by using the ppa).

If anybody could advise me regarding this problem I would be very grateful.

Martin
