Ubuntu 服务器 12.04.5 软件包 php5-mcrypt 不可用

Question

我在 Ubuntu Server 12.04.5 上我正在尝试安装 php5-mcrypt。我收到这个错误。

~$ sudo apt-get install php5-mcrypt

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package php5-mcrypt 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 'php5-mcrypt' has no installation candidate

我该如何解决这个问题？
