On a 14.04 system, I upgraded the kernel to 3.16 using:

sudo apt-get install --install-recommends linux-generic-lts-utopic xserver-xorg-lts-utopic libgl1-mesa-glx-lts-utopic libegl1-mesa-drivers-lts-utopic

Now a lot of packages like unity-control-center are broken. Also, refuses to install again. How can I fix this?

The main issue was Intel Graphics Installer. Remove it and the PPA. Then do sudo apt-get install ubuntu-desktop to recover all the broken packages

My only solution was to revert back to the old setup.

  1. Uninstall the kernel 3.16 with (replace the version with the right one)

    sudo apt-get purge linux-image-3.4.0-* linux-headers-3.4.0-*

  2. Remove everything which brought on the problem.

    sudo apt-get purge linux-generic-lts-utopic xserver-xorg-lts-utopic libgl1-mesa-glx-lts-utopic libegl1-mesa-drivers-lts-utopic

  3. Install the old version of these removed things with: 

    sudo apt-get install --install-recommends linux-generic xserver-xorg libgl1-mesa-glx libegl1-mesa-drivers

  4. Reinstall Ubuntu desktop.

    sudo apt-get install ubuntu-desktop
