每次我尝试运行升级时，都会出现以下错误。
root@Nixie:~# apt-get upgrade
Reading package lists... Done

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
nginx : Depends: nginx-core (< 1.4.6-1ubuntu3.3.1~) but 1.4.6-1ubuntu3.4 is installed or
nginx-full (< 1.4.6-1ubuntu3.3.1~) but it is not installed or
nginx-light (< 1.4.6-1ubuntu3.3.1~) but it is not installed or
nginx-extras (< 1.4.6-1ubuntu3.3.1~) but it is not installed or
nginx-naxsi (< 1.4.6-1ubuntu3.3.1~) but it is not installed
E: Unmet dependencies. Try using -f.

首先，您应该删除旧的 nginx（1.4.x），然后安装新的。nginx 1.8.x 和 1.4.x 有一些不兼容性，所以您不能轻易地升级它。
