When I open the Ubuntu One client on Windows, it will log in to the account, but when I press the "Connect" nutto, nothing happens. After I discovered that the cause is an error in syncdaemon. Here is the syncdaemon-exceptions.log : 2012-02-22 18:52:32,796 - twisted - ERROR - Unhandled error in Deferred: 2012-02-22 18:52:32,796 - twisted - ERROR - Unhandled Error Traceback (most recent call last): File "twisted\internet\udp.pyc", line 130, in doRead File "twisted\names\dns.pyc", line 1780, in datagramReceived File "twisted\internet\defer.pyc", line 361, in callback File "twisted\internet\defer.pyc", line 455, in _startRunCallbacks --- --- File "twisted\internet\defer.pyc", line 542, in _runCallbacks File "ubuntuone\syncdaemon\action_queue.pyc", line 828, in _make_connection File "C:\Program Files (x86)\ubuntuone\dist\library.zip\ubuntuone\storageprotocol\context.py", line 54, in get_ssl_context exceptions.NameError: global name 'ssl_cert_location' is not defined And syncdaemon.log: 2012-02-22 18:44:11,480 - ubuntuone.SyncDaemon.Main - INFO - Starting Ubuntu One client version 0.1 2012-02-22 18:44:11,482 - ubuntuone.SyncDaemon.Main - INFO - Using 'C:\\Users\\Luca\\Ubuntu One' as root dir 2012-02-22 18:44:11,482 - ubuntuone.SyncDaemon.Main - INFO - Using 'C:\\Users\\Luca\\AppData\\Local\\xdg\\ubuntuone\\syncdaemon' as data dir 2012-02-22 18:44:11,482 - ubuntuone.SyncDaemon.Main - INFO - Using 'C:\\Users\\Luca\\AppData\\Local\\xdg\\ubuntuone\\shares' as shares root dir 2012-02-22 18:44:11,483 - ubuntuone.SyncDaemon.tritcask - INFO - Initializing Tritcask on: C:\Users\Luca\AppData\Local\xdg\ubuntuone\syncdaemon\tritcask 2012-02-22 18:44:11,483 - ubuntuone.SyncDaemon.tritcask - DEBUG - lookingup data files 2012-02-22 18:44:11,486 - ubuntuone.SyncDaemon.tritcask - INFO - found 1 data files, 0 dead and 0 broken files 2012-02-22 18:44:11,486 - ubuntuone.SyncDaemon.tritcask - DEBUG - building the keydir, using: [u'1329776434038601'] 2012-02-22 18:44:11,486 - ubuntuone.SyncDaemon.tritcask - DEBUG - loading entries from (build_hint=False): C:\Users\Luca\AppData\Local\xdg\ubuntuone\syncdaemon\tritcask\1329776434038601.live.tritcask-v1.data 2012-02-22 18:44:11,487 - ubuntuone.SyncDaemon.tritcask - INFO - keydir ready!
