Nginx 未滿足的依賴項，無法升級/刪除

最近我在我的 Ubuntu 伺服器上安裝了 newrelic，之後我自動開始在日誌中出現錯誤，並且載入 newrelic 擴展失敗。

我嘗試升級/刪除 newrelic 但在這兩種情況下我都收到錯誤：

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.

我嘗試執行sudo apt-get -f install，但它導致輸出：

ubuntu@ip:/etc/php$ sudo apt-get -f install

我確實找到了一篇建議刪除 nginx 然後重新安裝的文章。這是一個具有持續流量的生產伺服器，所以我想避免解除安裝 nginx 的風險，然後再失敗。我已經更改了 nginx 的配置，並且沒有註意到我的所有更改。有什麼安全的方法可以解決這個問題嗎？

在研究和試驗了很多東西之後，我找不到任何解決方案，最後按照這個https://askubuntu.com/questions/243568/nginx-dependency-problem-trying-to-upgrade

我做了以下工作：

1. 我做了一個備份/etc/nginx
2. 然後刪除了nginx
3. 重新安裝nginx
4. 然後因為它被/etc/nginx備份文件夾替換並開始工作

我有大約 15-20 分鐘的停機時間來做這一切。

這可以通過將 force-overwrite 傳遞給底層 dpkg 程序來解決。這是我使用的命令：

sudo apt -o Dpkg::Options::="--force-overwrite" upgrade nginx
