我正在尝试在 Ubuntu 16.04 上安装 NVIDIA本网站说。输入后apt-get install nvidia-current，我收到以下错误：
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
nvidia-current : Depends: nvidia-304 but it is not going to be installed
unity-control-center : Depends: gnome-settings-daemon-schemas (>= 3.16) but it is not going to be installed
Recommends: system-config-printer-gnome but it is not going to be installed
Recommends: unity-control-center-faces but it is not going to be installed
unity-settings-daemon : Depends: gnome-settings-daemon-schemas (>= 3.16) but it is not going to be installed
Recommends: systemd-services
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
当我输入时apt-get -f install; apt-get install gnome-settings-daemon-schemas，出现以下错误：
