我有一个带有Chrome和Firefox的Selenium服务器4。Chrome运行良好，但当我尝试运行Firefox时，它给我带来了一个错误：
org.openqa.selenium.SessionNotCreatedException：无法创建新的远程会话。所需的能力=能力｛acceptInsecureCerts:true，browserName:firefox，marionette：true｝
驱动程序的Java代码在这里：
String browser = System.getProperty("browser");
browser = browser == null || browser.equals("") ? CHROME : browser.toLowerCase();
System.setProperty("webdriver.gecko.driver", "/home/tatrytec/custom-scripts/selenium-server/geckodriver");
Configuration.remote = HUB_URL;
Configuration.browser = browser;
FirefoxOptions options = new FirefoxOptions();
options.setCapability("marionette",true);
options.setHeadless(true);
WebDriver driver = new RemoteWebDriver(options);
WebDriverRunner.setWebDriver(driver);
这是Jenkins堆栈跟踪：

服务器上的权限似乎有问题。上面写着：
无法启动文档门户：拨号unix/run/user/0/bus:connect：权限被拒绝
不知道我还应该设置什么来运行。
这在使用snap安装的firefox中很常见您可以卸载firefox的快照版本，并通过使用apt进行安装
snap remove firefox
然后
sudo apt-get install firefox
sudo apt-get install firefox-geckodriver
