I'm trying to install Nitro with this :

sudo apt-get install nitro

And then I get this :

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

or been moved out of Incoming.

The following information may help to resolve the situation:



The following packages have unmet dependencies:

 nitro : Depends: gir1.2-launchpad-integration-3.0 but it is not installable

E: Unable to correct problems, you have held broken packages.

How do I solve this?

UPDATE

The output of cat /etc/apt/sources.list is :
