我正在尝试在刚刚安装的带有 Mate 桌面的 Ubuntu Server 15.10 上安装 nginx。
我做了一个快速更新：
sudo apt-get update
现在尝试安装 nginx：
sudo apt-get install nginx
这是我得到的：
server@Node1:~/nod$ sudo apt-get install nginx

这是我第一次使用 15.10，希望能更简单一些。我没有太多时间花在服务器安装上，正在考虑回滚到 14.xx。如果您有任何解决方案，请告知。
谢谢。

答案2
如果您已经安装了 Apache。
应用以下命令。
停止 apache2
service apache2 stop
然后安装 nginx
sudo apt-get install nginx
答案3
我遇到了同样的问题。关于 Apache 的建议不适用，因为我在安装过程中主动卸载了它。
/etc/nginx/nginx.conf事实证明，我看到的是 nginx 的配置文件和服务脚本之间发生冲突的结果/lib/systemd/system/nginx.service。
具体来说，服务脚本使用一些选项启动 nginx，包括daemon on：
$ cat /lib/systemd/system/nginx.service
...
[Service]
...
ExecStartPre=/usr/sbin/nginx -t -q -g 'daemon on; master_process on;'
ExecStart=/usr/sbin/nginx -g 'daemon on; master_process on;'
ExecReload=/usr/sbin/nginx -g 'daemon on; master_process on;' -s reload
...
我/usr/sbin/nginx -g 'daemon on; master_process on;'直接在终端上运行，出现了以下错误：
nginx: [emerg] "daemon" directive is duplicate in /etc/nginx/nginx.conf:1
我看了一下/etc/nginx/nginx.conf并发现（第 1 行）：
daemon off;
注释掉它并运行sudo apt-get -f install即可解决问题。
答案4
这是错误。您可以手动编辑修复程序。
我在 digitalocean repos 上有它。使用 virtualmin？
