Talk:Release notes/1.38

Hello,

I want to upgrade to 1.38 but I got the following error.

# sudo -u webXX php7.4 maintenance/update.php

PHP Fatal error:  Uncaught Wikimedia\Services\NoSuchServiceException: No such service: DBLoadBalancerFactory in /var/www/clients/web/vendor/wikimedia/services/src/ServiceContainer.php:468

Can you give me some hints how to solve this error?

Thanks

I found a solution. I disable

require_once( "$IP/includes/DefaultSettings.php" );

in LocalSettings.php.
