I would like to run chromedriver_autoinstaller. I follow example here: https://pypi.org/project/chromedriver-autoinstaller/
from selenium import webdriver
import chromedriver_autoinstaller
chromedriver_autoinstaller.install() # Check if the current version of chromedriver exists
# and if it doesn't exist, download it automatically,
# then add chromedriver to path
driver = webdriver.Chrome()
driver.get("http://www.python.org")
assert "Python" in driver.title
But I got an error:

selenium.common.exceptions.WebDriverException: Message: unknown error: DevToolsActivePort file doesn't exist
What does it mean? Is this package still working?
This error message...
org.openqa.selenium.WebDriverException: unknown error: DevToolsActivePort file doesn't exist
...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.
A common cause for Chrome to crash during startup is running Chrome as root user (administrator) on Linux. While it is possible to work around this issue by passing --no-sandbox flag when creating your WebDriver session, such a configuration is unsupported and highly discouraged. You need to configure your environment to run Chrome as a regular user instead.
Execute your test as a regular user.

I have a following problem. I would like to run chromium on my Ubuntu using chromedriver_autoinstaller. My code is:
from selenium import webdriver

chromedriver_autoinstaller.install() # Check if the current version of chromedriver exists
# and if it doesn't exist, download it automatically,
# then add chromedriver to path
options = webdriver.ChromeOptions()
driver = webdriver.Chrome(options = options)
driver.get("http://www.python.org")
But desired url http://www.python.org does not open, I just see data:, in the browser:
I tried to add some options, but it did not help:

# then add chromedriver to path
options = webdriver.ChromeOptions()
options.add_argument("--no-sandbox")
options.add_argument("--disable-dev-shm-usage")

I have the following script that makes use of selenium for authentication process.
I'm on Ubuntu 20.04 LTS, the computer was reformatted in the past few days, the same script worked before, from reading other threads I suspect that this has to do something with the root user/privileges.

...implies that the GeckoDriver was unable to locate the firefox executable while trying to initiate/spawn a new Browsing Context i.e. Firefox Browser session.
Reason
The two primary reasons for this error are as follows:
Firefox isn't installed within your system.
Firefox isn't installed at the default location within your system.
Solution
The possible solutions are:
If Firefox isn't installed in your system, you need to install it before executing your tests.
If Firefox is installed at a customized location, you need to pass the absolute path of the firefox binary as follows through an Options() instance:
from selenium import webdriver
options = webdriver.FirefoxOptions()
options.binary_location = r"C:/location/to/Firefox/Binary/firefox.exe"
driver = webdriver.Firefox(executable_path=r'C:\Users\Cody\Downloads\geckodriver.exe', options=options)
driver.get('http://inventwithpython.com/')

I'm unable to get chromium to run when i put my code in theoretically it looks like it should work i even followed tutorials but i keep getting the same error message. This is the code that i put:
from selenium import webdriver
#chromedriver varible with exact location to where its saved
chromedriver = "/home/jackmiller/Downloads/chromedriver"
#varible of drive to run open up the chrome driver which is located
#on my machine as chromedriver varible chromedriver
driver = webdriver.Chrome(chromedriver)
#open this website
driver.get('https://youtube.com')
and when i run the code in terminal this is what it returns:

It's not opening chromium at all
Have you tried: options.add_argument("--remote-debugging-port=9222")
From this bug report: https://github.com/SeleniumHQ/selenium/issues/6049
A workaround is to specify the remote debugging port as an argument for your ChromeOptions, something like: options.add_argument("--remote-debugging-port=9222"), and if you're running in a container make the driver headless like so options.headless = True, otherwise use something like pyvirtualdisplay for screenshots.
Are you tried make chromedriverfile executable?
sudo chmod a+x chromedriver

You need your chromedriver.exe to match your current chrome browser's version. To check your chrome version go into your chrome settings and select the about chrome tab. You can find your chrome version there. Then download the chromedriver from here that matches your version. Update the path in your code to this driver and it should work.
