I tried to update Ubuntu 12.04 through the update manager. After downloading all the updates, it asked me to restart the system for the installation of the downloaded packages, after which neither the update manager nor the software centre are working.

I'm getting the following message while trying to update through update manager:

The following packages have unmet dependencies:
aptitude: Depends: libapt-pkg4.12 (>= 0.8.16~exp12ubuntu6) but 0.8.16~exp12ubuntu10.2 is installed
          Depends: libboost-iostreams1.46.1 (>= 1.46.1-1) but it is not installed

I have tried using sudo apt-get install -f

In addition to this, during the booting operation I'm getting an error message:

You need to provide the output of sudo apt-get check and sudo dpkg -C. – Braiam Jun 25 '14 at 15:45
