Apt 指出它正在停止，因为它无法安装已安装的软件包/版本

它抱怨的软件包已经安装。我执行了“apt-get -f install”和“dpkg --configure -a”，但什么都没改变。我卸载并重新安装了依赖项。我还运行了“apt-get install --reinstall”。我用“dpkg -r --force-depends”删除了输出中的所有软件包（我正在安装的软件包、具有依赖项的其他软件包以及依赖项本身），然后再次从同一命令行安装了所有软件包。当我安装软件包时，它断言不是安装后，什么也没发生。有时 Apt 认为它们在那里，有时却不在那里。

是我忽略了什么，还是有什么事情发生了？

它只是进入了一个糟糕的状态。我只是不断尝试运行重新安装，并不断将所有提到的软件包添加到命令行，直到它工作正常。最终，它封装了所有与freeglut3-dev包（我真正想要安装的唯一包）：

apt-get install --reinstall freeglut3-dev gnome-control-center unity-control-center libcheese7 libcheese-gtk23 libclutter-1.0-0 libclutter-gtk-1.0-0 libclutter-gst-2.0-0 gstreamer1.0-clutter libcogl-pango15 libcogl15
