unknown error: DevToolsActivePort file doesn't

Question

I have an ubuntu server having the UI as well. U can execute the test cases by firing mvn test command. But the problem is when I do ssh of the machine through the terminal from another machine I get the following error-

unknown error: DevToolsActivePort file doesn't exist
  (Driver info: chromedriver=2.40.565383 (76257d1ab79276b2d53ee976b2c3e3b9f335cde7),platform=Linux 4.4.0-121-generic x86_64) (WARNING: The server did not provide any stacktrace information)

but the same command starts chrome successfully if I take remote of the machine through remmina and then execute the same command of this machines terminal.

Answer 1

Try this method to instantiate chrome web driver could help you to overcome this issue in ubuntu :

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

opt = Options()
opt.add_argument("--no-sandbox")
opt.add_argument("--disable-dev-shm-usage")

driver = webdriver.Chrome(chrome_options=opt, 
    executable_path='<your-chromedriver-path>')
driver.get('https://www.google.com/')
