GD Library extension not available with this PHP installation Ubuntu Nginx

I am using Laravel web framework on my ubuntu 14.04 server and Nginx web server, I have this error when I try to upload a file using Laravel to the server. my upload directory is on the public/uploads folder that has 777 permission.

The GD Graphics Library is for dynamically manipulating images. For Ubuntu you should install it manually:

• PHP8.1: sudo apt-get install php8.1-gd
• PHP8.2: sudo apt-get install php8.2-gd
• PHP8.3: sudo apt-get install php8.3-gd

That's all, you can verify that GD support loaded:

php -i | grep -i gd

Output should be like this:

GD Support => enabled
GD headers Version => 2.1.1-dev
gd.jpeg_ignore_warning => 0 => 0

and finally restart your apache:

sudo service apache2 restart
