Answer 1

I found this question after I was getting the same (2nd) error as you:

$ aws s3 ls

A client error (AccessDenied) occurred when calling the ListBuckets operation: Access Denied

It turns out that there is a specific policy permission that you need to add to be able to list all the available buckets:

{
    "Sid": "AllowListingOfAllBuckets",
    "Effect": "Allow",
    "Action": [
        "s3:ListAllMyBuckets"
    ],
    "Resource": [
        "arn:aws:s3:::*"
    ]
},

As you don't state which command you were running to generate the error, I can't say whether this will be helpful to the OP, but hopefully it will help someone else who stumbles upon this post in the same situation as me.

Answer 2

I had a very similar problem. My user had S3FullPermissions and I could create buckets and list all of them:

aws s3 mb s3://my-bucket
make_bucket: s3://my-bucket/

aws s3 ls
2017-03-24 12:30:34 my-bucket

But when I tried to run:

aws s3 ls s3://my-bucket
A client error (AccessDenied) occurred when calling the ListObjects operation: Access Denied

The error itself was related with the awscli version I was using and not with any misconfiguration of my buckets/users/policies. To solve it, I removed the awscli package installed from my distro repository and installed it using pip:

# apt-get remove awscli
# pip install awscli

Hope this help someone in a similar situation, I have wasted several hours trying to guess what was going on here.
