Guys, I am getting the above error when trying to run the following script :-

import time


from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.common.exceptions import TimeoutException, \
    ElementNotVisibleException


binary = FirefoxBinary(r'/usr/local/bin/firefox')

caps = DesiredCapabilities.FIREFOX.copy()

caps['marionette'] = True


def init_driver():
    driver = webdriver.Firefox(firefox_binary=binary,
                               capabilities=caps,
                               executable_path=r'/usr/local/bin/geckodriver')
    driver.wait = WebDriverWait(driver, 5)
    return driver


def lookup(driver, query):
    driver.get("http://www.google.com")
    try:
        box = driver.wait.until(EC.presence_of_element_located(
            (By.NAME, "q")))
        button = driver.wait.until(EC.element_to_be_clickable(
            (By.NAME, "btnK")))
        box.send_keys(query)
        try:
            button.click()
        except ElementNotVisibleException:
            button = driver.wait.until(EC.visibility_of_element_located(
                (By.NAME, "btnG")))
            button.click()
    except TimeoutException:
        print("Box or Button not found in google.com")


if __name__ == "__main__":
    driver = init_driver()
    lookup(driver, "Selenium")
    time.sleep(5)
    driver.quit()

I have followed all the steps described in this post but still it ain't working!
Please help me with this!

make your /usr/local/bin/geckodriver executable:

$ sudo chmod +x /usr/local/bin/geckodriver'

I already did that @cgoldberg! Upon doing ls -ld, it shows "drwxrwxrwx"
