AWS Boto connection only works from Windows Python shell

Currently, I am trying to connect to AWS from an Ubuntu 14 VM running inside a Windows 8 OS. In the Ubuntu shell, I run:

$AWS_ACCESS_KEY=my_access_key
$AWS_SECRET_ACCESS_KEY=my_secret_key
$python
$export AWS_ACCESS_KEY
$export AWS_SECRET_ACCESS_KEY
$python
>>>import os
>>>from boto import ec2
>>>auth = {"aws_access_key_id":os.environ.get("AWS_ACCESS_KEY"),
>>>"aws_secret_access_key":os.environ.get("AWS_SECRET_ACCESS_KEY")}
>>>conn = ec2.connect_to_region("us-east-1", **auth)
>>>conn.get_all_instances()

The error message I get is

boto.exception.EC2ResponseError: EC2ResponseError: 401 Unauthorized
AuthFailure
AWS was not able to validate the provided access credentials

At first I thought that my credentials weren't being provided correctly. However, in Windows:

C:\>SET AWS_ACCESS_KEY=my_access_key
C:\>SET AWS_SECRET_ACCESS_KEY=my_secret_key
C:\>python
>>>import os
>>>from boto import ec2
>>>auth = {"aws_access_key_id":os.environ.get("AWS_ACCESS_KEY"),
>>>"aws_secret_access_key":os.environ.get("AWS_SECRET_ACCESS_KEY")}
>>>conn = ec2.connect_to_region("us-east-1", **auth)
>>>conn.get_all_instances()

Returns all of the reservations as expected. I compared the value of auth from both Python shells, and they are the same. The Python and boto versions appear to be the same. I haven't tried using a boto config file, but I would prefer not to, as this is a component of a script that should be deployable by multiple users in my organization.

Is there a better way to pass my authentication? Is there some nuance to Linux/Windows that I'm missing?

I had this issue, and it was actually a very simple problem I hadn't even thought of. AWS will give a credentials issue (even if the bucket is public access) if the system is missing the config file in the .aws directory. I used WinSCP to transfer the .aws file from my home directory on windows to my home directory on the linux system and it ran without issues

The new convention is to use AWS_ACCESS_KEY_ID not AWS_ACCESS_KEY probably you have an older version of Boto on your Windows machine.
