WebDriverException: Message: unknown error: Chrome failed to start: exited abnormally using Selenium ChromeDriver and Chrome through WebDriverManager

Question

I'm running this script:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from selenium.webdriver.chrome.service import Service
from webdriver_manager.chrome import ChromeDriverManager
service = Service(executable_path=ChromeDriverManager().install())
driver = webdriver.Chrome(service=service)
from selenium.webdriver.common.by import By

chrome_options = Options()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')

driver = webdriver.Chrome(ChromeDriverManager().install(),options=chrome_options)

driver.get('http://192.168.15.1/me_configuracao_avancada.asp',)
user = driver.find_element(By.ID, "txtUser")
user.send_keys("support")
pass_ = driver.find_element(By.ID, "txtPass")
pass_.send_keys("password")
btnLogin = driver.find_element(By.ID, "btnLogin")
btnLogin.click()
driver.get('http://192.168.15.1/reboot.asp',)
reboot = driver.find_element(By.ID, "btnReboot")
reboot.click()
alert = driver.switch_to.alert
alert.accept()
print("Modem Reiniciado!")

I'm using Google Chrome 103.0.5060.134, ChromeDriver 103.0.5060.134 and Selenium version 4.3.0. But when I run the script, this error messages appears:

Some weeks ago the script ran without any issues, but now it gives this error. How can I correct it?

You need to take care of a couple of things here as follows:

• You need webdriver.Chrome() only once. If you don't need the arguments through Options() keep:

   driver = webdriver.Chrome(service=service)

  and remove:

   driver = webdriver.Chrome(ChromeDriverManager().install(),options=chrome_options)

  or vice versa.

• If you are executing as a non-root using add_argument('--headless') generally you may not even require the following arguments:

  • add_argument('--no-sandbox')
  • add_argument('--disable-dev-shm-usage')

• You can try to initiate the new Browsing Context ie google-chrome-headless using:

   driver = webdriver.Chrome(service=ChromeDriverManager().install(), options=chrome_options)

• Your effective code block will be:

   from selenium import webdriver from selenium.webdriver.chrome.options import Options from selenium.webdriver.chrome.service import Service from webdriver_manager.chrome import ChromeDriverManager chrome_options = Options() chrome_options.add_argument('--headless') # optional chrome_options.add_argument('--no-sandbox') # optional chrome_options.add_argument('--disable-dev-shm-usage') driver = webdriver.Chrome(ChromeDriverManager().install(),options=chrome_options) driver.get('http://192.168.15.1/me_configuracao_avancada.asp')

Note : Ensure that you have installed webdriver-manager and Chrome browser within your system before you kickoff your test execution.
