This question already has an answer here:

Keep trying to update Ubuntu 12.04 but it keeps telling me that my package system is broken. I run apt-get -f install and get this :

    owner@MyLaptop:~$ sudo apt-get -f install
[sudo] password for owner:

The following packages were automatically installed and are no longer required:

  linux-headers-3.5.0-32-generic compiz-plugins compiz-plugins-main
  python-compizconfig python-central linux-headers-3.5.0-23
  linux-headers-3.5.0-32 linux-headers-3.5.0-34 linux-headers-3.5.0-23-generic
Use 'apt-get autoremove' to remove them.
The following extra packages will be installed:

The details I get from the update manager are:

    The following packages have unmet dependencies:

sudo apt-get clean it will clean the repository or you dpkg is installing another package in Ubuntu software center or in another terminal. or you break any package during installing. check that and run sudo apt-get update
