最近我在我的Ubuntu服务器上安装了newrelic，之后我自动开始在日志中出现错误，未能加载newrelic扩展。
我试图升级/删除newrelic，但在这两种情况下，我得到一个错误：
ubuntu@ip:/etc/php$ sudo apt-get upgrade Reading package lists... Done Building dependency tree Reading state information... Done You might want to run 'apt-get -f install' to correct these. The following packages have unmet dependencies: nginx : Depends: nginx-core (< 1.10.0-0ubuntu0.16.04.4.1~) but 1.10.3-0ubuntu0.16.04.1 is installed or nginx-full (< 1.10.0-0ubuntu0.16.04.4.1~) but it is not installed or nginx-light (< 1.10.0-0ubuntu0.16.04.4.1~) but it is not installed or nginx-extras (< 1.10.0-0ubuntu0.16.04.4.1~) but it is not installed E: Unmet dependencies. Try using -f. 我试着运行sudo apt-get -f install但是输出结果：

我find了一篇build议删除nginx然后重新安装的文章。 这是一个持续stream量的生产服务器，所以我想避免卸载nginx，然后失败的风险。 我已经改变了nginx的configuration，并没有logging我所有的变化。 有没有办法解决这个问题？
这可以通过强制覆盖到底层的dpkg进程来解决。 这是我用的命令：
sudo apt -o Dpkg::Options::="--force-overwrite" upgrade nginx

经过研究和尝试了很多东西，我找不到任何解决scheme，并最终按照这个https://askubuntu.com/questions/243568/nginx-dependency-problem-trying-to-upgrade
我做了以下：
/etc/nginx的备份 /etc/nginx与备份文件夹，并开始工作 我有一个15-20分钟的停机时间做这一切。
