You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 nginx : Depends: nginx-full (>= 1.6.2-5+deb8u4) but it is not installed or
                  nginx-light (>= 1.6.2-5+deb8u4) but it is not installed or
                  nginx-extras (>= 1.6.2-5+deb8u4) but it is not installed
         Depends: nginx-full (< 1.6.2-5+deb8u4.1~) but it is not installed or
                  nginx-light (< 1.6.2-5+deb8u4.1~) but it is not installed or
                  nginx-extras (< 1.6.2-5+deb8u4.1~) but it is not installed
E: Unmet dependencies. Try using -f.

Answer 1

试着运行以下命令

sudo apt-get remove nginx && sudo apt-get purge nginx
sudo apt-get install nginx

清除应用程序的删除配置文件，但如果应用程序没有删除配置文件，则会出现问题。

&&仅在执行前一个命令时执行，退出代码0(连续) echo $?将向您显示应用程序的退出代码。

如果所有这些都失败了，请尝试运行dpkg -l|grep nginx并查找输出中的前两个字母，以查看nginx包安装的状态。

Answer 2

试试这个：

sudo apt-get purge nginx
sudo apt-get install nginx

我用的是ubuntu 14.04，这对我来说很管用。
