I'm running ubuntu 16 and I'm trying to install php5.6 extension GD.
I understand that php5.6 isn't available anymore in the default ubuntu repo's. I followed How can I downgrade from PHP 7 to PHP 5.6 on Ubuntu 16.04? to install php5.6 on my machine. But for my drupal site the GD php extension is required.
However it's not in the proposed repo. Can someone point me to the correct repo where I can still download/install the GD extension? Or an alternative method because I'm not finding it.
