Question

我读了“使用Rails进行敏捷Web开发”这本书，并在第16.1章中关于Apache / Passenger 停止了。我需要安装gem passenger和apache2-module。 Gem已成功安装，但我无法告诉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

   Please install it with apt-get install libapr1-dev

 * To install Apache Portable Runtime Utility (APU) development headers:

好的，我尝试安装这个必需的软件，例如：

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

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libcurl4-openssl-dev : Depends: libidn11-dev but it is not installable
                        Depends: libkrb5-dev but it is not installable
                        Depends: librtmp-dev but it is not installable

有什么问题？
