broken with newest pyrax

[Simao]

After upgrading to duplicity 0.6.23-0ubuntu0ppa21~saucy1 cloudfiles support no longer works.

First it fails saying the `cf+http` backend requires `pyrax`:

    BackendException: This backend requires the pyrax library available from Rackspace.

After installing pyrax with `sudo pip install pyrax`, I get the following error:

Traceback (most recent call last):
  File "/usr/bin/duplicity", line 1489, in <module>
    with_tempdir(main)
  File "/usr/bin/duplicity", line 1483, in with_tempdir

    action = commandline.ProcessCommandLine(sys.argv[1:])

    self.container = pyrax.cloudfiles.create_container(container)
AttributeError: 'NoneType' object has no attribute 'create_container'

Also, there is the `--cf-backend` option documented in the man page, but duplicity doesn't actually support it:

duplicity: error: no such option: --cf-backend

duplicity 0.6.23

Hello,

Same issue here, with Ubuntu 14.04 LTS and also duplicity 0.6.23.

@kevin

You need to define the CLOUDFILES_REGION environment variable to your cloudfiles region, in my case it's "LON"

@simaomm

Thank you for your answer, but it did not change anything for me.

Actually I was a little tired when I posted my comment, my issue is different from yours: I do not have the Python error and the traceback, I only need to use the cloudfiles backend but pyrax is used instead and I have the error “no such option: --cf-backend” when I try to revert to the cloudfiles backend using the option specified in the manpage.

Hello,
this option is available only in duplicity 0.6.24 and not in duplicity 0.6.23 even if it's written in CHANGELOG.
I'm under Ubuntu 14.04 and I have downloaded the version from debian SID (http://ftp.fr.debian.org/debian/pool/main/d/duplicity/duplicity_0.6.24-1_amd64.deb)
And now it works.
