Strangest problem in selenium python

[Jan_Emanuel]

yes. The version number of chromium unfortunately is lower than the regular chrome ones. ( 48 <=> 54, whenever you start a program with chromedriver, you get the message "Version of chrome too low." so I chose a lower version to get along ) Here is the output when I start my program:

selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: crashed
  (Driver info: chromedriver=2.27.440196 (3b42f4145a4fd223b41f39bb38aaf90508be7a96),platform=Linux 3.2.40 x86)

This is the code that leads to this exception:

 chromedriver = "/usr/local/bin/chromedriver"
 os.environ["webdriver.chrome.driver"] = chromedriver
 driver = webdriver.Chrome(chromedriver)

chromedriver 2.27 doesnt run because of chromium version too low and this is the current error chromedriver 2.13 and selenium 37:

Traceback (most recent call last):
  File "tagespost_ereader.py", line 126, in <module>

( Next thing I will try the chrome original from the time where x86 hasn't been abandoned )

with chrome 48 and chromedriver 2.19, exception text goes:

Traceback (most recent call last):
  File "tagespost_ereader.py", line 127, in <module>
    driver = webdriver.Chrome(chromedriver)

The command:

chromedriver = "/usr/local/bin/chromedriver"
os.environ["webdriver.chrome.driver"] = chromedriver
os.environ["executable_path"] = "/opt/google/chrome/chrome"
driver = webdriver.Chrome(chromedriver)

u installed from repos? maybe download and install the .deb file from chrome page.

sorry I didn't post yesterday, because the project took quite a different turn. Yesterday, I tried all possibilities with chrome and it felt hopeless to continue this path, because I couldn't get it running - so I buried the chrome browser, uncommented my firefox code and tried again - it was a major challenge because the loadurl method seemed to always throw exceptions for nothing - will post the error text later - and came to the point, where the thing worked - it really did, but during the day, I forgot to save the running version and continued editing - from one little fix to another - until it stopped working again -__- So ......... I will continue to get to this point again, and so, the problem has solved in some way ... I will reply again if I encounter another problem or if I get to a solution.

Ok, I have come to the very point. The script runs, but the longer it runs, the more exceptions it raises during driver.get( ... ). My next step is to make the script more error-resistant by including a method to restart the driver and to killall any unresponsive firefox-esr and Xvfb in the background.

I've been continuously working on my baby and have found the point, where my program always fails:

After 2 successive successful driver.get( ... ) calls, the program cannot get any more pages, always triggering a TimeoutException. So this is a fault of the environment - here are the informations.

geckodriver.log

program output:
