Problem / Steps
Using the latest docker image ( 10.2.2 ), the form goes until asking the info about the name for the website, contact and user info.
On submitting that form, it just gets back to the same form, does't show any error.
On the docker service log shows the error:
trace:\n#0 /opt/drupal/web/core/modules/mysql/src/Driver/Database/mysql/TransactionManager.php(31): Drupal\\Core\\Database\\Connection->getClientConnection()\n#1 /opt/drupal/web/core/lib/Drupal/Core/Database/Transaction/TransactionManagerBase.php(278): Drupal\\mysql\\Driver\\Database\\mysql\\TransactionManager->processRootCommit()\n#2 /opt/drupal/web/core/lib/Drupal/Core/Database/Transaction.php(88): Drupal\\Core\\Database\\Transaction\\TransactionManagerBase->unpile()\n#3 [internal function]: Drupal\\Core\\Database\\Transaction->__destruct()\n#4 {main}\n thrown in /opt/drupal/web/core/lib/Drupal/Core/Database/Connection.php on line 306, referer: http://rasp51:8001/core/install.php?rewrite=ok&langcode=pt-pt&profile=standard&id=3&op=start
Ignoring the form and going to the main page, the title for the website is correct, but the login page doesn't accepted the user.
On the Docker service cmd line, you can create the user with "drush uli".
It seems that it isn't able to create new users on a MySQL database from the installation form.
