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?

Presuming you are executing as a non-root user, 1) can you remove the arguments --no-sandbox and --disable-dev-shm-usage. 2) Does your tests execute well in non --headless mode? – Headmaster

So i remove the arguments --no-sandbox, --disable-dev-shm-usage and --headless, but the error continues, i'm running the script on Ubuntu Server 20.4.3 LTS – Freak

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 i.e. 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.
