安装php5-dev Ubuntu 16.04

Question

I am following this tutorial to enable thread safety in php 5.6. https://blog.bensoer.com/compile-thread-safe-php-5-6-20-from-source/ But when i am executing sudo apt-get install -y php5-dev It gives me the following output.

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

How can I resolve this in Ubuntu 16.04?
