The error message that "ext-fileinfo" is missing from your system when trying to install a package in Aapanel, generally occurs because the PHP extension "fileinfo" is not installed or enabled on your server.
"fileinfo" is a built-in PHP extension used to determine the MIME type of a file by looking for certain magic byte sequences at specific positions within the file.
You can resolve this issue by installing and enabling the "fileinfo" extension. The exact steps to do this will depend on your server's operating system and PHP version, but here are some general steps you can follow:
- Check if the fileinfo extension is installed, by running the command php -m and look for 'fileinfo' in the list.
- If it's not listed, install it. On Ubuntu, Debian, and other Debian-based systems, you can install it by running this command: sudo apt-get install php-fileinfo. On Centos, Fedora, and other RedHat-based systems, you can use this command: sudo yum install php-fileinfo.
- Once it's installed, you need to add extension=fileinfo.so to your PHP configuration file, which is usually located at /etc/php.ini or /etc/php/php.ini
- Finally, restart your web server for the changes to take effect.
- after that, you can check that the module is loaded by running php -m | grep fileinfo and it should return 'fileinfo' if it's loaded.
This should resolve the issue of "ext-fileinfo" missing error, and allow you to install the package in Aapanel.
It's always a good idea to take a backup of your current configuration before making any changes, in case something goes wrong.
