Tryng to install (and after updating composer):
composer create-project symfony-cmf/sandBox cmf-sandBox
I have those errors:
Installing symfony-cmf/sandBox (2.0.0) - Installing symfony-cmf/sandBox (2.0.0): Loading From cache Created project in cmf-sandBox Loading composer repositories with package information Installing dePEndencies (including require-dev) from lock file Your requirements Could not be resolved to an installable set of packages.

Edit: Continuing the recommendation of Timo,I was able to install the project by executing the following:
composer create-project --ignore-platform-reqs symfony-cmf/sandBox cmf-sandBox
but I have oBTained the following errors:
PHP Fatal error: Uncaught Symfony\component\Debug\Exception\ContextErrorException: Warning: count(): Parameter must be an array or an object that implements Countable in /srv/http/symfony/cmf-sandBox/vendor/symfony-cmf/routing/src/ChainRouter.PHP:101 Stack trace: #0 /srv/http/symfony/cmf-sandBox/vendor/symfony-cmf/routing/src/ChainRouter.PHP(308): Symfony\Cmf\Component\Routing\ChainRouter->all() #1 /srv/http/symfony/cmf-sandBox/VAR/cache/dev/appDevDebugProjectContainer.PHP(1670): Symfony\Cmf\Component\Routing\ChainRouter->setContext(Object(Symfony\Component\Routing\RequestContext)) #2 /srv/http/symfony/cmf-sandBox/vendor/symfony/symfony/src/Symfony/Component/DependencyInjection/Container.PHP(335): appDevDebugProjectContainer->getCmfRouting_RouterService() #3 /srv/http/symfony/cmf-sandBox/var/cache/dev/appDevDebugProjectContainer.PHP(4955): Symfony\Component\DependencyInjection\Container->get(‘cmf_routing.rou...‘) #4 /srv/http/symfony/cmf-sandBox/vendor/symfony/symfony/src/Symfony/Component/DependencyInjection/Container.PHP(33 in /srv/http/symfony/cmf-sandBox/vendor/symfony-cmf/routing/src/ChainRouter.PHP on line 101
The project uses a Symfony version 3 structure and may have some incompatibility with PHP 7.3 (as Timo says).
