php - Install GD on PHP 5.6

Question

My web app is running on PHP 5.6.4 and Nginx on Ubuntu Ubuntu 16.04.1.

I am getting the following error in my browser:

FPDF error: GD extension is required for GIF support

I have recently reinstalled the server locally, so I am presuming GD library needs to be installed. So I ran the following commands:

sudo apt-get install php5.6-gd

sudo service php5.6-fpm restart

sudo service nginx restart

But I am still getting the same error message, can anyone advise what I should do please?
