Authentication fails for juju 1.25.6 on aws

[Domas Monkus]

Attempting to bootstrap a juju model on aws, using juju 1.25.6 on a trusty vm results in an authentication failure:
```
d@ubuntu:~$ juju switch amazon
amazon -> amazon
d@ubuntu:~$ juju bootstrap --debug

Please ensure the Access Key ID you have specified is correct.
You can obtain the Access Key ID via the "Security Credentials"
page in the AWS console.
```

Creating an ec2 instance directly through the web dashboard works. Bootstrapping a model (using the same credentials) with juju 2.0.0 on xenial works just fine as well.

@Domas,

1.25 series is upto to 1.25.10. Could you please re-test with latest version?

If you are running Ubuntu, you can get it from the juju proposed ppa:

    sudo add-apt-repository ppa:juju/1.25
    sudo apt-get update; sudo apt-get install juju-core

Seems to work with 1.25.10

Excellent \o/
Thanks, Domas :) I'll mark as Invalid.
