解除安裝 Phusion 乘客和維修包數據庫

前段時間，我使用這些說明安裝了 Phusion Passenger 。我的 sources.list 中也有 debdeb.org 儲存庫。

我現在想從 dobdeb.org 刪除乘客並安裝一個乾淨的 nginx 包。移除passenger模組不是問題。但是，如果我嘗試刪除nginx-extrasornginx-common包，我會得到以下結果

$ sudo apt-get remove nginx-common nginx-extras
Reading package lists... Done

The following package was automatically installed and is no longer required:

Use 'apt-get autoremove' to remove it.
The following extra packages will be installed:

 libaprutil1-dbd-sqlite3 libaprutil1-ldap
Suggested packages:
 apache2-doc apache2-suexec apache2-suexec-custom
The following packages will be REMOVED:
 nginx-common nginx-extras
The following NEW packages will be installed:
 apache2 apache2-mpm-worker apache2-utils apache2.2-bin apache2.2-common libapr1 libaprutil1
 libaprutil1-dbd-sqlite3 libaprutil1-ldap
0 upgraded, 9 newly installed, 2 to remove and 5 not upgraded.

似乎我的包數據庫在某種程度上被破壞了，我想知道如果我刪除了 nginx-extras，為什麼還要安裝 apache2。

如何刪除 nginx-extras 和 nginx-common 而無需安裝 apache2 並在之後安裝“乾淨”版本？

我會假設你安裝的東西有一個被安裝的 nginx 或 apache2 滿足的依賴項。

嘗試使用aptitude why apache2和/或aptitude why nginx-common查看任何潛在的關係。
