OSError: [Errno 8] Exec format error when trying to run chromedriver for selenium

Question

I am trying to run Selenium based tests on an Ubuntu based server from Jenkins but get the following cryptic errors:

First:

+ python manage.py jenkins --enable-coverage --settings=Modeling.settings.dev

And then a bit further down:

Traceback (most recent call last):
  File "/var/lib/jenkins/jobs/GS_modelling_web_tests/workspace/modeling/Modeling/tests/BaseTest.py", line 18, in setUp
    self.browser = webdriver.Chrome( ChromeDriver.path() )
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/chrome/webdriver.py", line 61, in __init__
    self.service.start()
  File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/common/service.py", line 62, in start
    stdout=self.log_file, stderr=self.log_file)
  File "/usr/lib/python2.7/subprocess.py", line 710, in __init__
    errread, errwrite)
  File "/usr/lib/python2.7/subprocess.py", line 1327, in _execute_child
    raise child_exception
OSError: [Errno 8] Exec format error

For the first error I have seen Scrapy with selenium, webdriver failing to instantiate but that seems to be something else related to shutting down? And the second error seems related to shebangs according to OSError: [Errno 8] Exec format error but I haven't managed to understand whether I can use that information. What's going on here?

I have a similar error which I have [posted here](https://stackoverflow.com/questions/52297117/exec-format-error-while-trying-to-run-a-python-application-in-linux-based-os). Thanks for any help! — Nocturnal, Sep 12 '18 at 18:18

OSError: [Errno 8] Exec format error

ChromeDriver executable available here is not supported on Ubuntu platform. For Ubuntu use chromedriver for ubuntu http://chromedriver.storage.googleapis.com/2.23/chromedriver_linux32.zip or http://chromedriver.storage.googleapis.com/2.23/chromedriver_linux64.zip
