Centro de software do Ubuntu: Incapaz de corrigir problemas, você realizou pacotes quebrados

Question

Centro de software de pacotes não encontrado no Ubuntu 14.04 LTS.

Eu tentei instalá-lo via terminal, mas acabei com erro abaixo:

ravip@LP204:~$ sudo apt-get install software-center
[sudo] password for ravip:

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:
 software-center : Depends: software-center-aptdaemon-plugins but it is not going to be installed
                   Depends: python-gi but it is not going to be installed
                   Depends: python-gi-cairo but it is not going to be installed
                   Depends: python-aptdaemon (>= 0.40) but it is not going to be installed
                   Depends: python-aptdaemon.gtk3widgets but it is not going to be installed
                   Depends: oneconf (>= 0.2.6) but it is not going to be installed
                   Recommends: software-properties-gtk but it is not going to be installed
                   Recommends: sessioninstaller but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Todos Depends & Recommends Pacotes já estão instalados & na versão mais recente.

Como posso resolver?
