【问题描述】：

我读了《Agile Web Development with Rails》一书，停在第 16.1 章关于 Apache/Passenger。我需要安装 gem 乘客和 apache2-module。宝石已成功安装，但我不能告诉同样的 apache 模块。

终端：

~$passenger-install-apache2-module

Installation instructions for required software

 * To install Curl development headers with SSL support:
   Please run apt-get (!!!) install libcurl4-openssl-dev or libcurl4-gnutls-dev, whichever you prefer.

 * To install Apache 2 development headers:
   Please install it with apt-get install apache2-threaded-dev

 * To install Apache Portable Runtime (APR) development headers:
   Please install it with apt-get install libapr1-dev

 * To install Apache Portable Runtime Utility (APU) development headers:
   Please install it with apt-get install libaprutil1-dev

好的，我试试安装这个必备软件，例如：

alexkd@Active-pc ~ $ sudo apt-get install libcurl4-openssl-dev
[sudo] password for alexkd:

The following information may help to resolve the situation:

The following packages have unmet dependencies:

                        Depends: libkrb5-dev but it is not installable
                        Depends: librtmp-dev but it is not installable
E: Unable to correct problems, you have held broken packages.

有什么问题？

【问题讨论】：

你试过sudo apt-get update吗？你可能有一些破损的包裹。乘客提示还提供libcurl4-gnutls-dev 作为替代选项。
~$ sudo apt-get update。在 19 秒内获取 803 kB (41,8 kB/s) 读取包列表...完成 W：GPG 错误：archive.ubuntu.com raring 发布：以下签名无效：BADSIG 40976EAF437D05B5 Ubuntu 存档自动签名密钥。这个错误是什么意思？

非常感谢，康纳！

yum install curl-devel

在 Debian 和 Ubuntu 中：

apt-get install libcurl-dev
