我试过apt-get 安装 nginx还有一个项目：

nginx is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
nginx : Depends:
nginx-core (>= 1.4.6-1ubuntu3.2) but it is not going to be installed or
nginx-full (>= 1.4.6-1ubuntu3.2) but it is not going to be installed or
nginx-light (>= 1.4.6-1ubuntu3.2) but it is not going to be installed or
nginx-extras (>= 1.4.6-1ubuntu3.2) but it is not going to be installed or
nginx-naxsi (>= 1.4.6-1ubuntu3.2) but it is not going to be installed
Depends: nginx-core (< 1.4.6-1ubuntu3.2.1~) but it is not going to be installed or
nginx-full (< 1.4.6-1ubuntu3.2.1~) but it is not going to be installed or
nginx-light (< 1.4.6-1ubuntu3.2.1~) but it is not going to be installed or
nginx-extras (< 1.4.6-1ubuntu3.2.1~) but it is not going to be installed or
nginx-naxsi (< 1.4.6-1ubuntu3.2.1~) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
我应该这么做apt-get -f 安装? 那会有什么作用？

答案1
它与sw-nginx包冲突：

trying to overwrite '/usr/sbin/nginx', which is also in package sw-nginx 1.6.0-1.14060313.ubuntu1404
去掉它：
sudo apt-get purge sw-nginx
