@benjamin-carl Could you understand it?

Deprecation Notice: The callback Clickalicious\PhpMemAdmin\Installer::postInstall declared at 
/home/prg652/website/phpMemAdmin/vendor/clickalicious/phpmemadmin/lib/Clickalicious/PhpMemAdmin/Installer.php
 accepts a Composer\Script\CommandEvent
but post-install-cmd events use a Composer\Script\Event instance.
Please adjust your type hint accordingly, see https://getcomposer.org/doc/articles/scripts.md#event-classes
in phar:///usr/local/bin/composer/src/Composer/EventDispatcher/EventDispatcher.php:289
