Answer 1

I ran into same issue, i am using UBUNTU, PYTHON and OPERA browser. in my case the problem was originated because i had an outdated version of operadriver.

Solution: 1. Make sure you install latest opera browser version ( do not use opera beta or opera developer), for that go to the official opera site and download from there the latest opera_stable version.

2. Install latest opera driver (if you already have an opera driver install, you have to remove it first use sudo rm ...)

wget https://github.com/operasoftware/operachromiumdriver/releases/download/v.80.0.3987.100/operadriver_linux64.zip

   unzip operadriver_linux64.zip
   sudo mv operadriver /usr/bin/operadriver
   sudo chown root:root /usr/bin/operadriver
   sudo chmod +x /usr/bin/operadriver

in my case latest was 80.0.3987 as you can see

3. Additionally i also installed chromedriver (but since i did it before testing, i do not know of this is needed) in order to install chromedriver, follow the steps on previous step :v

4. Enjoy and thank me!

Sample selenium code

from selenium import webdriver

driver.get("http://www.python.org")
assert "Python" in driver.title
elem = driver.find_element_by_name("q")
elem.clear()
elem.send_keys("pycon")
elem.send_keys(Keys.RETURN)
assert "No results found." not in driver.page_source
driver.quit()
