selenium.common.exceptions.InvalidArgumentException: Message: invalid argument: value must be a non-negative integer

[Jeffrey Walton]

I am using Selenium, Python, Chromedriver and Chrome browser to fill in a web form. The script automates filing FTC Do Not Call complaints. The script runs on Armbian, which is Ubuntu Bionic on armv7l.

The problem below is new and arrived today, which is June 19, 2019. File ftc.py:111 is 'implicitly_wait':

    driver.get("https://complaints.donotcall.gov/complaint/complaintcheck.aspx")
    driver.implicitly_wait(2)

I see similar problems with Firefox, but I don't see Chrome (yet). A Firefox example is https://stackoverflow.com/q/46541636/608639.

I've tried to build these tools in the past, like Geckodriver. It looks like no testing occurs on ARM. For ARM, Rust cannot build the Cargo packages, which means Geckodriver cannot be built. Trying to do anything with Rust, Cargo and Geckodriver is a complete waste of time.

Here's the reproducer.

from selenium.webdriver.chrome.options import Options

def get_chrome():
    if os.path.isfile('/usr/bin/chromium-browser'):
        return '/usr/bin/chromium-browser'
    elif os.path.isfile('/usr/bin/chromium'):
        return '/usr/bin/chromium'
    elif os.path.isfile('/usr/bin/chrome'):
        return '/usr/bin/chrome'
    elif os.path.isfile('/usr/bin/google-chrome'):
        return '/usr/bin/google-chrome'
    else:
        return None

def main():
    if version.parse(selenium.__version__) >= version.parse("3.0"):
        opts = Options()
        opts.binary_location = get_chrome()
        opts.add_argument('--headless')
        opts.add_argument('--no-sandbox')
        opts.add_argument('--disable-dev-shm-usage')

        driver = webdriver.Chrome(chrome_options=opts)
        driver.maximize_window()
    else:

        driver.maximize_window()

    agent = driver.execute_script('return navigator.userAgent')

    driver.implicitly_wait(2)

Someone on Stack Overflow suggested the installed version of Selenium is incompatible with Chrome 75. I'm trying to find the minimum version of Selenium that should be installed to avoid the issue.

Due to policies and procedures, pip is not an option for us. It is not allowed on our production machines. The only packages allowed are those provided by the distro or the software we write.

If Selenium is the issue, then this probably affects both Bionic and Cosmic since both provide 3.8.0+dfsg1-3. It looks like Disco bumps to 3.14.1+dfsg1-1.

Confirmed, it looks like python3-selenium is incompatible with the updated chromium-webdriver package in 18.04. As a workaround, the selenium package from PyPI (pip3 install selenium) does work.
