Online Accounts doesn't show Twitter OAuth page

[Sah Lee]

To reproduce:
System Settings -> Online Accounts -> Add account... -> Twitter

Expected:
Twitter OAuth page shown, asking for my login and permission

Actually:
Nothing shown, but a gray bar saying "Please authorize Ubuntu to access your Twitter account".
Even the black spinner doesn't show up.

Additional info:
I'm behind a proxy.
I can open Twitter with my browser.
I can add other accounts like Facebook and Google.
I see the same problem when adding Sina account.

Please let me know how and which if I could provide any log.

Status changed to 'Confirmed' because the bug affects multiple users.

Hi Sah, and thanks for reporting this bug!
Unfortunately, we know that Sina is not working properly. However, Twitter should be working fine. If you are confident enough to use the Terminal, could you please open it and try the following, while the Online Accounts panel is *closed*:

  killall signon-ui
  export SSOUI_LOGGING_LEVEL=2
  signon-ui

then try to reproduce the bug again (attempt to create a Twitter account) and attach the signon-ui output to this bug report. That will probably provide us enough information to understand what is going wrong.

[Sah Lee (leesah)]

Hi Alberto,

It seems signon-ui won't open any window for me. Any clue?

[Alberto Mardegan (mardy)]

Yes, that's normal, it shouldn't open any window when you launch it. But when you start creating the twitter account, you should see some messages appearing in the terminal.

[Sah Lee (leesah)]

OK. I thought it was a shortcut to open the Online Accounts window. :-D

I tried just now. Problem reproduced. But no output in terminal.
And then I tried setting the log level to 3, still no luck.
Every time I tried I did after a reboot, so that the red gear icon on the top-right corner turns back to white again.

[Walter Ribeiro (wribeirojr)]

Same thing here, no messages showed in the terminal.

[Alberto Mardegan (mardy)]

OK, so it seems that something is broken before the request even gets to signon-ui.
Could you please do the following then:

  sudo gedit /etc/signond.conf

Then uncomment (remove the initial ";") the line with "LoggingLevel", and set the level to 2. Then save the file and quit gedit.
Then,

  killall signond

And try to create a twitter account again. It should still fail, but at least this time there will be some information logged into the /var/log/syslog file. It would be great if you could copy the last part of it, from the line "Signond SUCCESSFULLY initialized" on, and paste it here (make sure that no passwords are logged; they shouldn't be, but please double check and, if you find them, just overwrite them with some random text).

[Sah Lee (leesah)]

Sorry. Should've used this uploading function.

[Alberto Mardegan (mardy)]

Thanks Sah! It seems that there is a network error...
Can you please tell me what happens when you try to load these URLs in your browser?

https://api.twitter.com/oauth/request_token
https://api.twitter.com/oauth/access_token
https://api.twitter.com/oauth/authorize

They will probably not return any useful content, but what I'm interested in knowing is whether you get some error or whether you are redirected to other pages.
Another question: are you behind a proxy?

[Sah Lee (leesah)]

request_token gives 401 Unauthorized and a message "Failed to validate oauth signature and token".
access_token also gives 401 Unauthorized and no additional message.
authorize gives 403 Forbidden and a Twitter style web page saying there's a lack of some token.

Yes, I am behind a proxy. But I didn't meet any problem adding other accounts like Facebook or Google.

[Walter Ribeiro (wribeirojr)]

Response for the 3 URLs:

1: "There is no request token for this page. It is the special key that we need to receive from app that asked to use your account in Twitter. Please, return to site or app that sent you here and try again; probably it's just an error." (text in Portuguese, my translation)
2: blank page, no response.
3: "Failed to validate oauth signature and token"

For me this issue is solved, in Ubuntu 13.04

Solved in my Raring too.

[Alberto Mardegan (mardy)]

This was most likely proxy support not working properly. Closing the bug report.
