I just installed Ubuntu 12.04. Then I want to setup Ubuntu One but the installer freezes at this line.

Traceback (most recent call last):
File "/usr/lib/python2.7/dist-packages/ubuntuone-installer/ubuntuone/installer/gui.py", line 357, in finished
File "/usr/lib/python2.7/dist-packages/gi/types.py", line 43, in function
return info.invoke(*args, **kwargs)
gi._glib.GError: Failed to execute child process "ubuntuone-control-panel-gtk" (No such file or directory)

I tried to install ubuntuone-control-panel-gtk package but failed.

ubuntuone-control-panel-gtk : Depends: python-aptdaemon.gtkwidgets but it is not going to be installed or python-aptdaemon-gtk but it is not going to be installed

Please help.
