Hubic: Please check your credentials

[Paul]

First of all, I'm using OS X 10.10.3, python 2.7.6 and virtualenv 1.11.6.

I've downloaded the development version of duplicity from this project site and extracted it on my computer.

Then I ran the following commands

virtualenv ~/.virtualenv/hubic
source ~/.virtualenv/hubic/bin/activate
cd duplicity-0.7.02
./setup.py install
pip install lockfile
pip install pyrax
pip install requests_oauthlib

I've created a file in ~/.hubic_credentials with 700 permissions with the following content:

[hubic]
email = <email address hidden>
password = myPassword
client_id = api_hubic_mU3UFGva5EwS4LDB1hXMiXmPfu4sdETo
client_secret = 3u3jf09VDaatyXDIWYA5esV9jwD3iGz4hFsM18JstLG0eS3xaqCd7PJH87654nDM
redirect_uri = http://localhost/

I then run ./bin/duplicity . cf+hubic://default -v9, which returned this error message

I verified that the email and the password are correct after copying and pasting the credentials from the file and logging into the website.
I've generated the API key in the developers section under my account and copied the keys from there.

Can anyone here reproduce that?

[Ignace Mouzannar (ghantoos)]

I stumbled on the same bug. It seems it is due to an error processing special characters in the password. It works if only using alphanum password. I will try to look into this.

[Ignace Mouzannar (ghantoos)]

Erratum: the error is due to the "%" character being present anywhere in the configuration variables.

[Raphaël F. (rflores)]

I'm also concerned, we currently cannot use a % in password and I believe this character should be correctly parsed for such a field.

Please provide a way to escape it.

[Raphaël F. (rflores)]

Several person have reported the problem and it is clearly identified.

[Raphaël F. (rflores)]

Here is the return statement:

2016-08-19 11:09:24 rflores@ulis-desktop:~$ duplicity ~/Documents/ cf+hubic://Documents
Connection failed, please check your credentials: InterpolationSyntaxError '%' must be followed by '%' or '(', found: 'my_password_with_a_%_which_is_not_parsed_correctly'

[Raphaël F. (rflores)]

As mentioned by the return statement, escaping % with a second % is OK.
So instead of:
my_password_with_a_%_which_is_not_parsed_correctly
Use:
my_password_with_a_%%_which_is_not_parsed_correctly

[Raphaël F. (rflores)]

As mentioned by the return statement, escaping % with a second % is OK.
So instead of:
my_password_with_a_%_which_is_not_parsed_correctly
Use:
my_password_with_a_%%_which_is_not_parsed_correctly

The password can be escaped.
