ubuntu で Selenium を Python から動かそうとして

Traceback (most recent call last):
  ... 省略 ...

となったら

wget https://github.com/mozilla/geckodriver/releases/download/v0.14.0/geckodriver-v0.14.0-linux64.tar.gz
tar -zxvf geckodriver-v0.14.0-linux64.tar.gz
sudo mv geckodriver /usr/local/bin/

最新版リリースはここで確認 https://github.com/mozilla/geckodriver/releases

ちなみに、webdriver.Firefox のコンストラクタは

    def __init__(self, firefox_profile=None, firefox_binary=None,
                 timeout=30, capabilities=None, proxy=None,
                 executable_path="geckodriver", firefox_options=None,
                 log_path="geckodriver.log"):
        """Starts a new local session of Firefox.

こうなので、executable_path に geckodriver のフルパスを指定しても良さそう
