Issue Problems with installing memcached for PHP 8.2

Server operating system version

Ubuntu 20.04.5

Plesk version and microupdate number

Obsidian 18.0.49

I was able to install memcached with this work around. This was possible for PHP 8.0 and also for version 8.1. PHP 8.2 however makes problems.
After “service plesk-php82-fpm restart” comes the following message:

Job for plesk-php82-fpm.service failed because the control process exited with error code.
See "systemctl status plesk-php82-fpm.service" and "journalctl -xe" for details.

After “/opt/plesk/php/8.2/bin/php -m | grep memcached” comes the following message:

PHP Warning:  PHP Startup: Unable to load dynamic library 'memcached.so' (tried: /opt/plesk/php/8.2/lib/php/modules/memcached.so (/opt/plesk/php/8.2/lib/php/modules/memcached.so: cannot open shared object file: No such file or directory), /opt/plesk/php/8.2/lib/php/modules/memcached.so.so (/opt/plesk/php/8.2/lib/php/modules/memcached.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

Why is the file memcached.so not to be found under this path “/opt/plesk/php/8.2/lib/php/modules”? What can I do?

Is the file there on the right place?
Did you assign the correct permissions to that file?

In your message: "/opt/plesk/php/8.2/lib/php/modules/memcached.so.so"

... so.so ? <- may be this might be the problem?!

Was this ever figured out?

It's embarrassing. I made the same mistake I did with PHP 8.0.

The php.ini was the cause. Here are the steps for the installation:

apt install memcached autoconf automake gcc libmemcached-dev libhashkit-dev pkg-config plesk-php*-dev zlib1g-dev
/opt/plesk/php/8.2/bin/pecl install memcached

add "extension=memcached.so" to php.ini
Following:

echo "extension=memcached.so" > /opt/plesk/php/8.2/etc/php.d/memcached.ini
plesk bin php_handler --reread
service plesk-php82-fpm restart
service apache2 restart
/opt/plesk/php/8.2/bin/php -m | grep memcached
