With AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY properly exported, and
no '.*(proxy|PROXY).*' environment variables, all my aws ec2 commands
fail in the same exact fashion:

  # aws ec2 --region us-east-1 describe-instances --instance-ids [...]

  get_environ_proxies() missing 1 required positional argument: 'no_proxy'

I have another sid system where "aws ec2" is fully fonctional, and the
only difference I could readily identify was python3-requests (a
python3-botocore dependency) being 2.12.4-1 instead of
2.18.1-1. However, downgrading to that on the affected system does not
fix the issue.

I could not find any reference to the error message anywhere, so I'm
filing this bug so it can be first indexed, and hopefully later triaged
properly.

Cheers,

I believe this should be linked to a bug with botocore. The pip3 version of
awscli pulls in botocore 1.7.34 and works properly on the same system.
