Селеновый Хромедрайвер не запустится

Question

Я пытаюсь проверить свой код, используя селен с драйвером Chrome. Но я всегда получал это сообщение об ошибке в моем терминале.

======================================================================
ERROR: test_input_status (myweb.tests.StorySixFunctionalTest)

  (unknown error: DevToolsActivePort file doesn't exist)
  (The process started from chrome location /snap/bin/chromium is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

И я поместил свой хромедрайвер в тот же каталог, что и manage.py моего проекта. А вот код из моего test.py

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.chrome.options import Options

class StorySixFunctionalTest(TestCase):

    def setUp(self):
        chrome_options = Options()
        self.selenium = webdriver.Chrome('./chromedriver',chrome_options = chrome_options)
        chrome_options.add_argument('--dns-prefetch-disable')
        chrome_options.add_argument('--no-sandbox')
        chrome_options.add_argument('--headless')
        chrome_options.add_argument('disable-gpu')
        chrome_options.addArguments("--disable-extensions");
        chrome_options.addArguments("--disable-dev-shm-usage");
        super(StorySixFunctionalTest, self).setUp()

    def tearDown(self):
        self.selenium.quit()
        super(StorySixFunctionalTest, self).tearDown()

    def test_input_status(self):
        selenium = self.selenium
        selenium.get('http://127.0.0.1:8000/index/')

        status = selenium.find_element_by_id('id_status')
        submit = selenium.find_element_by_id('submit')

        status.send_keys("Coba Coba")
        submit.send_keys(Keys.RETURN)

Обновление:

Я пытаюсь отладить свою программу, показывая журнал chromedriver, и вместо этого я получил эту ошибку (котораястранно, потому что у меня установлен модуль canbera)
