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

I'm having trouble installing the libapache2-mod-fastcgi module which is required in order for me to use PHP-FPM with Apache. When I try to install using this command

sudo apt-get install libapache2-mod-fastcgi

which results in this error.

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

My sources.list looks like this

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

I have tried following the directions listed here but I just get errors when I run sudo apt-get update so I removed those repositories because it made no difference I still couldn't install the module and it wasn't fetching anything.

Try to add multiverse in your sources.list, and then apt-get update or sudo apt-get update. It should do the trick.
