To install PHP 8.3 on Ubuntu 24.10, follow these steps.

Step 1 : Run the following command to ensure your package lists are up to date:

sudo nano /etc/apt/sources.list.d/ondrej-ubuntu-php-oracular.sources

- Find the word oracular and replace it with noble

- Save and close the file.

Step 3 : Update the package lists to reflect the changes:

sudo apt update

Step 4 : To ensure the correct version of the libgd3 package is used, create a preferences file with specific pinning settings:

sudo nano /etc/apt/preferences.d/ondrejphp

Add the following lines:

Package: libgd3

Pin-Priority: 900

Save and close the file.
