Description: HTTP library with thread-safe connection pooling for Python
urllib3 supports features left out of urllib and urllib2 libraries.
* Re-use the same socket connection for multiple requests (HTTPConnectionPool and HTTPSConnectionPool) (with optional client-side certificate verification).
* File posting (encode_multipart_formdata).
* Built-in redirection and retries (optional).
* Supports gzip and deflate decoding.
* Thread-safe and sanity-safe.
* Small and easy to understand codebase perfect for extending and building upon.

У меня есть другая установка с теми же версиями хром-драйвера хром-браузера, и ошибка не возникает. Что еще я мог проверить?
Есть еще указатели?
UPDATE
В среде, где проблема не возникает, версия pip не совпадает.
pip v1.5.4 вместо pip install --upgrade pip==1.5.4
Теперь удалите pip 18.1 и переустановите мои pip-пакеты.
Чтобы установить обратно последнюю версию pip, если вы хотите вернуться снова
python -m pip install --upgrade pip
Также отметил, что на работающей машине у меня немного другая версия GCC
gcc --version
gcc (Ubuntu 4.8.4-2ubuntu1~14.04.3) 4.8.4
Решено
Мне пришлось начать со свежей установки Xubuntu и запустить
sudo pip install -U urllib3
