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 the-ubuntu-documentary: 
Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

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?
