Duplicity

Dropbox backend: global name 'rest' is not defined when changing app id and secret

Asked by Cyrus David

Steps I did:

1. `curl -L http://code.launchpad.net/duplicity/0.6-series/0.6.24/+download/duplicity-0.6.24.tar.gz | tar xz`
2. `cd duplicity-0.6.24`
3. `vim duplicity/backends/dpbxbackend.py` and change the `APP_KEY` and `APP_SECRET` values.
4. `sudo checkinstall python setup.py install`

The error:

```

can you try to add the following line

 global client, rest, session

as line 103 into

 /usr/local/lib/python2.7/dist-packages/duplicity/backends/dpbxbackend.py"

?

it should then look like

...
    def __init__(self, parsed_url):
        duplicity.backend.Backend.__init__(self, parsed_url)

        global client, rest, session
        from dropbox import client, rest, session
...

does that work?.. ede/duply.net

@edso yes, it does! Thank you. Now it successfully shows the error:

dpbx error: [403] u"Invalid app key (consumer key). Check your app's configuration to make sure everything is correct."

I checked the app key, secret and they are correct.

I removed the lines calling the function etacsufbo() and it worked. Is that function something that's specifically just for the default key and secret?

dunno.. i am not author. the backend comment says

# This application key is registered in my name (jno at pisem dot net).
# You can register your own developer account with Dropbox and
# register a new application for yourself, obtaining the new
# APP_KEY and APP_SECRET.
# Note 1: you must not store your credentials "as is" in the code.
# The values must be "processed" at least.
# This is a must for "production" keys.
# Note 2: the name of the application defines the name of the
# subfolder in the "Apps" folder.
# http://www.dropbox.com/developers/apps is the place to get the key.

are your values _processed_ ? ..ede

I wanted to put the files at the root. Instead of `Apps/duplicity`.

> what exactly.. processing or the author's address? ..ede/diply.net

I just removed the etacsufbo() function calls haha, they're to be used on my servers anyway so I don't see the point of doing that.

Thank you so much for helping me!

just figured out that etacsufbo() is inverted for obfuscate().. which is neither secure not anything as the backend delivers the deobfuscation code.

Actually, I'm a big fan of git, but hate moving. Catch-22!

:) It's not about Ubuntu, I believe we were hosted on Savannah before?
And their UI was/is awful. LP at the time was putting effort into being a
nice project host. They've seemed to have stopped working so much on that
though.
