deb仓库 添加/etc/apt/sources.list加上如下两条
deb http://Nginx.org/packages/ubuntu/ trusty Nginx
deb-src http://Nginx.org/packages/ubuntu/ trusty Nginx

然后有可能出线pgp钥匙不匹配的问题
W: GPG error: http://Nginx.org trusty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY xxxxxx
把这个xxxx传下下面的命令中去
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys xxxxxx

之后
sudo apt-get update
sudo apt-get install Nginx
安装稳定版
