在ubuntu 14.04中安装libapache2-mod-fastcgi，软件包不可用

Question

我在安装libapache2-mod-fastcgi模块时遇到了问题，这是我为Apache使用PHP-FPM所必需的。当我尝试使用此命令安装时

sudo apt-get install libapache2-mod-fastcgi 

这会导致此错误。

Package libapache2-mod-fastcgi is not available, but is referred to by another package. 
This may mean that the package is missing, has been obsoleted, or is only available from another source 

E: Package 'libapache2-mod-fastcgi' has no installation candidate 

我的sources.list看起来像这样

deb http://archive.ubuntu.com/ubuntu trusty main restricted universe 
deb http://archive.ubuntu.com/ubuntu trusty-updates main restricted universe 
deb http://security.ubuntu.com/ubuntu trusty-security main restricted universe $ 
deb http://archive.canonical.com/ubuntu trusty partner 

## modifications made here will not survive a re-bundle. 
## a.) add 'apt_preserve_sources_list: true' to /etc/cloud/cloud.cfg 
## b.) add sources in /etc/apt/sources.list.d 
# 
# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to 
deb http://us-west-2.ec2.archive.ubuntu.com/ubuntu/ trusty main 


## distribution. 
deb-src http://us-west-2.ec2.archive.ubuntu.com/ubuntu/ trusty-updates main

我曾尝试下面这里列出的方向，但我只是得到错误，当我执行sudo apt-get的更新，所以我删除了这些信息库，因为它使没有区别我仍然无法安装模块，它没有获取任何东西。

尝试在您的sources.list中添加multiverse，然后apt-get update或sudo apt-get update。它应该做的伎俩。
