Unable to locate package php7.3-gd

Question

I get the error from my cakephp 2.x project:

The PHP GD extension is required, but is not installed.

I use php7.3 with apache on debian

I search and find

apt-get install php7.3-gd

I tried this but i only get following error:

E: Unable to locate package php7.3-gd
E: Couldn't find any package by glob 'php7.3-gd'
E: Couldn't find any package by regex 'php7.3-gd'

I searched again, but didnt find a soulution for this problem only for ubunto and nothing else worked. I hope someone could help me with this problem.

Answer 1

It looks like you do not have the appropriate repo added. Try :

sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
sudo apt-get install -y php7.3-gd

Answer 2

@Will's answer did not work for me, I then replace the first command from sudo add-apt-repository ppa:ondrej/php to sudo apt-add-repository ppa:ondrej/php and it works for me. So finally I run:

sudo apt-add-repository ppa:ondrej/php    
sudo apt-get update
sudo apt-get install -y php7.3-gd
