My Selenium program doesn't start up. I have done this a long time ago, and my old programs don't run either due to software updates. I suspect that I have given the wrong path to Chrome and the driver, because the driver "failed to start", but I'm not sure. I'm running Python in PyCharm, the machine is Linux (hence no exe file).
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
url = "https://www.python.org"
options = webdriver.ChromeOptions()
options.binary_location = "/home/username/Documents/.../my-bot/chrome-linux64/chrome"
chrome_driver_binary = "/home/username/Documents/.../my-bot/chromedriver_linux64/chromedriver"
driver = webdriver.Chrome(service=Service(chrome_driver_binary), options=options)
driver.get(url)
The error message I get:
"/home/username/Documents/.../my-bot/venv/bin/python" /home/username/Documents/.../my-bot/main.py

(The process started from chrome location /home/username/Documents/.../my-bot/chrome-linux64/chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

I tried running it as a service, it didn't work either. I tried running Firefox instead, it didn't change anything.
I tried running my own program from a few months ago, it didn't work either (gecko driver is in the PATH variable, if I recall right, but Selenium doesn't work any more probably due to an update). This is a fragment of the old program:
from selenium import webdriver
import requests
from selenium.webdriver.firefox.options import Options as FirefoxOptions
import traceback
url = "https://www.python.org"
options = webdriver.FirefoxOptions()
driver = webdriver.Firefox(options=options)
driver.get(url)
The two main causes of DevToolsActivePort file doesn't exist are:
The first is fixable by changing Chrome options:
options.add_argument("--disable-dev-shm-usage")
options.add_argument("--no-sandbox")
The second is fixable by running in headless mode:
options.add_argument("--headless") # Old headless Chrome
# OR:
options.add_argument("--headless=new") # New headless Chrome
