1. Check your sources.list file
Verify that your sources.list file contains the appropriate repository locations. This file can be edited using the following command:

deb http://deb.debian.org/debian bullseye main
deb-src http://deb.debian.org/debian bullseye main
deb http://security.debian.org/debian-security/ bullseye-security main

2. Check your PHP configuration
If you are experiencing problems with PHP, you may need to examine its configuration. This can be accomplished by entering the following command:

Change [version] with the version of PHP installed on your server (e.g. 7.4). Ensure that your configuration file contains the necessary application settings.
