Problem when attempting to put Ubuntu One in panel (12.04)

I wanted to put the Ubuntu One icon in the panel so I could see the progress of my sync but when I try this is what I get....

mohd-arafat-hossain@TUD:~$ sudo apt-get install ubuntuone-indicator
[sudo] password for mohd-arafat-hossain:

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 ubuntuone-indicator : Depends: indicator-ubuntuone but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

I have done these following steps before I did the above >>

sudo add-apt-repository ppa:rye/ubuntuone-extras
sudo apt-get update

I have scanned for broken packages in Synaptic Package Manager but it shows that I have none.

Any help?
