Detailed information:

Ubuntu 22.04 (jammy) with PHP 8.1, I got a warning message always when call php-cli after install php-facedetect package:

PHP Warning: PHP Startup: Unable to load dynamic library 'facedetect.so' (tried: /usr/lib/php/20210902/facedetect.so (/usr/lib/php/20210902/facedetect.so: cannot open shared object file: No such file or directory), /usr/lib/php/20210902/facedetect.so.so (/usr/lib/php/20210902/facedetect.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

I tried to find the location of the 'facedetect.so" file but I can not found.
I checked the installer package too, but it is not contain this file as well.
I installed the package directly with command: apt-get install php-facedetect
On Ubuntu 18.04 (with PHP7.2) the php-facedetect package works perfectly.

This seems to be a packaging error.

If you compare the contents in the Ubuntu package in jammy
https://packages.ubuntu.com/jammy/amd64/php-facedetect/filelist
with the contents in Debian
https://packages.debian.org/sid/amd64/php-facedetect/filelist
or with the Ubuntu package in bionic
https://packages.ubuntu.com/bionic/amd64/php-facedetect/filelist
then you see that the facedetect.so file is missing.
