title: Issues copying a bucketfile to local disk
body: <p>I've ran through the entire sequence that I believe I needed to do, but I am still getting an <code>invalid argument type error</code> while trying to copy my file locally. What am I doing wrong here?</p>
  
  <pre><code>vagrant@dev:~$ aws s3 ls s://bucketname-vagrant
  
  A client error (NoSuchBucket) occurred when calling the ListObjects operation: The specified bucket does not exist
