iam trying to use the Selenium Webdriver on Ubuntu 20.04 with Google Chrome 116.0.5845.96 and the matching chromedriver.
Some Java Code that is supposed to start the driver:
import java.time.Duration;
import java.util.ArrayList;
import java.util.List;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.support.ui.WebDriverWait;
public class KASPwebcrawler {
public int getAverageProgressValue() throws InterruptedException {
// Für Headless
ChromeOptions options = new ChromeOptions();
options.addArguments("--log-level=DEBUG");
options.addArguments("--headless");
System.setProperty("chromedriver", "/Users/XXX/Downloads");
WebDriver driver = new ChromeDriver(options);
driver.manage().window().maximize();
driver.get("https://web.ankiapp.com/auth");
// Aufrufen Auth Tab
WebElement loginPage = driver.findElement(By.xpath("//*[text()='Einloggen']"));
loginPage.click();
Thread.sleep((long) (10000 * Math.random()));
// Eingeben der Login Info
WebElement username = driver.findElement(By.id("ion-input-3"));
WebElement password = driver.findElement(By.id("ion-input-4"));
username.sendKeys("XXX");
password.sendKeys("XXX");
// Login
List<WebElement> elements = driver.findElements(By.xpath("//*[text()='Einloggen']"));
WebElement login = elements.get(1);
login.click();
// Landen auf */home Website sicherstellen
WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(10));
wait.until(webDriver -> webDriver.getCurrentUrl().contains("/home"));
// Sleep nach Login
Thread.sleep((long) (3000 * Math.random() + 1000));
// Herunterladen von Deck: Datenbanken
getDeck("Datenbanken", driver);
getDeck("Info II.3", driver);
getDeck("Methoden II", driver);
// Liste für spätere Berechnung der Werte
List<Integer> valueList = new ArrayList<Integer>();
// Progress bei Decks auslesen
for (WebElement element : getProgressValueList(driver)) {
valueList.add(getTwoDecimals(element.getText()));
}
System.out.println("Durchschnittswert: " + getAverage(valueList));
// Beendet den Webdriver
return getAverage(valueList);
}
public void getDeck(String pDeckName, WebDriver pDriver) throws InterruptedException {
String deckName = ("//*[text()='" + pDeckName + "']");
// Herunterladen von Deck: Datenbanken
WebElement deckButton = pDriver.findElement(By.xpath(deckName));
deckButton.click();
Thread.sleep((long) (3000 * Math.random() + 1000));
WebElement downloadButton = pDriver.findElement(By.xpath("//*[text()='Herunterladen']"));
downloadButton.click();
Thread.sleep((long) (3000 * Math.random() + 1000));
pDriver.navigate().back();
Thread.sleep((long) (1000 * Math.random() + 1000));
}
public int getTwoDecimals(String pProgressValueString) {
String result = "0";
if (!pProgressValueString.isBlank()) {
String[] splitProgressValueString = new String[2];
splitProgressValueString = pProgressValueString.split("%");
result = splitProgressValueString[0];
}
return Integer.parseInt(result);
}
public List<WebElement> getProgressValueList(WebDriver pDriver) {
List<WebElement> progressValues = pDriver.findElements(By.className("end-slot"));
return progressValues;
}
public int getAverage(List<Integer> pProgressValueList) {
int result = 0;
int countActualValues = 0;
for (Integer zahl : pProgressValueList) {
if (zahl != 0) {
countActualValues += 1;
result += zahl;
}
}
return result / countActualValues;
}
}
When i start the java code it first tells me that the driver was started sucessfully, but the chrome session can not be initiated.
Errors read like that:

I think i have narrowed it down to the chromedriver not being able to interact with chrome. Both the driver and and browser are properly installed. Headless tests with the browser on its own worked as well. Thanks for help in advance.
I wanted to webscrape a Site with selenium on a ubuntu 20.04 VM
