Sonata-NewsBundle does not install on Symfony 3.2.9

Question

I use Symfony 3.2.9 and I try install Sontata News Bundle 3.0.0 . The bundle doesnt install . Is there a solution for Symfony 3.2.* yet?

My requirement (composer.json):

"require": {
  "php": ">=7.0",
  "doctrine/doctrine-bundle": "^1.6",
  "doctrine/doctrine-cache-bundle": "^1.2",
  "doctrine/orm": "^2.5",

        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installRequirementsFile",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::prepareDeploymentTarget"
    ],
    "post-install-cmd": [
        "@symfony-scripts"
    ],
    "post-update-cmd": [
        "@symfony-scripts"
    ]
},

    "symfony-var-dir": "var",
    "symfony-web-dir": "web",
    "symfony-tests-dir": "tests",
    "symfony-assets-install": "relative",
    "incenteev-parameters": {
        "file": "app/config/parameters.yml"
    },
    "branch-alias": {
        "dev-master": "3.2-dev"
    }
}

Anwser of the console:

Your requirements could not be resolved to an installable set of     packages.
Problem 1
- sonata-project/news-bundle 3.1.0 requires symfony/framework-bundle    ^2.3 -> satisfiable by symfony/framework-bundle[v2.3.0, v2.x.x ...].

• symfony/framework-bundle v2.6.9 requires symfony/translation ~2.6 -> satisfiable by symfony/translation[2.6.x-dev, 2.7.x-dev, 2.8.x-dev, v2.6.0, v2.6.0-BETA1, v2.6.0-BETA2, v2.6.1, v2.x.x, ...] but these conflict with your requirements or minimum-stability.

Should I install a version of old symfony?
