I have following error:You might want to run 'apt-get -f install' to correct these:The following packages have unmet dependencies:linux-kernel-generic : Depends: linux-image-3.11.0-12-generic but it is not going to be  installed                    Depends: linux-image-extra-3.11.0-12-generic but it is not going to be installedE: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).I tried to remove this using this commands but no effect. I'm getting the same error.sudo apt-get purge --auto-remove linux-image-extra-3.11.0-12-genericsudo apt-get purge linux-image-extra-3.11.0-12-genericThanks for all tips.Edit:I tried apt-get -f install but the same problem. Also synaptics can't remove this.Edit2:$ apt-cache policy Package files:100 /var/lib/dpkg/status release a=now500 http://ppa.launchpad.net/xorg-edgers/ppa/ubuntu/ saucy/main i386 Packages release
