The default config.inc.php-dist is missing a version variable so the following error is displayed to the user. I performed a fresh install with composer and found this issue. Also, the version displayed for a fresh composer install is "vv6.0.0-RC8-20-g1bc0ba72", but I was expecting RC9.
Your config.inc.php is out of date. You will need to regenerate it from the new config.inc.php-dist.
