I installed the nvidia-driver-346.47 after adding xorg-edgers ppa (using sudo add-apt-repository ppa:xorg-edgers/ppa ) to my system.
Wanted to setup packages for openGL development. While trying to install freeglut3-dev I get the following message: //======================== Terminal Output ======================================= The following packages have unmet dependencies: unity-control-center : Depends: libcheese-gtk23 (>= 3.4.0) but it is not going to be installed Depends: libcheese7 (>= 3.0.1) but it is not going to be installed E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages. //======================== Terminal Output ======================================= Giving: "sudo apt-get -o Debug::pkgProblemResolver=yes dist-upgrade" outputs: ======================== Terminal Output ======================================= Reading package lists...
