Bug Description

Hi.

The package python{,3}-selenium uses a hardcoded path of '/usr/lib/chromium/chromedriver' when instantiating a Chrome webdriver.

That path is correct for Debian (in particular, it was directly inherited from https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=805733#5), but since Ubuntu uses chromium-browser instead of Debian's chromium naming. The package chromium-chromedriver in Ubuntu installs the webdriver at '/usr/lib/chromium-browser/chromedriver'.

There needs to be a synchronization between the selenium Python module and the webdriver package.

Thanks,

Rogério Brito.

I'd like to add the resulting error is not very helpful.
Here's the error message I get

WebDriverException: Message: 'chromedriver' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

Adding the path to chromedriver to PATH like this doesn't actually help:

export PATH=$PATH:/usr/lib/chromium-browser

This will be fixed in chromium itself, to behave how Debian does

Note that when using python{,3}-selenium, the default path can be overridden like that:

  from selenium import webdriver
  driver = webdriver.Chrome(executable_path="/usr/lib/chromium-browser/chromedriver")

While I'm happy to see this fix released, I'm not so happy that it broke all of our company's Selenium-based scripts running on Ubuntu 16.04 by making a non-backwards-compatible change in an LTS release. All of our scripts had been written to accommodate the "buggy" behavior that has been present since Xenial's release by specifying the ChromeDriver path at '/usr/lib/chromium-browser/chromedriver'. Now, after applying the latest security updates, these scripts are finding that their ChromeDriver has gone missing.

In order to provide backwards-compatibility on the LTS releases, could you please provide (in a packaging update) a symlink at the old '/usr/lib/chromium-browser/chromedriver' location pointing to the new '/usr/bin/chromedriver' location?

Thanks for your consideration of this request.

Sorry about that oversight Brett. I'll provide a packaging update to fix that.
