Comment 8 for bug 488256

I'm sorry to hear Ubuntu One is not working properly for you. If you would like to help debug the problem that would be greatly appreciated. You can do the following in order to provide important details that will help determine the root cause of this issue?

1) Quit the Ubuntu One client

2) Open Applications->Accessories->Terminal, then run the command:
  mv ~/.cache/ubuntuone/log ~/.cache/ubuntuone/log_old && mkdir ~/.cache/ubuntuone/log

3) Run the following to open/create this file:
gedit ~/.config/ubuntuone/syncdaemon.conf

    #Add the following 2 lines to this file and save:
    [__main__]
    log_level = DEBUG

4) Open Ubuntu One Applications->Internet->Ubuntu One

5) Let Ubuntu One run for a bit, copy some files into your Ubuntu One Folder. Then attach the following logs to this bug: ~/.cache/ubuntuone/log/syncdaemon.log & ~/.cache/ubuntuone/log/syncdaemon-exceptions.log

Thank you,
