Answer 1

After all the discussion within the comments it seems you erred the command to download GeckoDriver and possibly some issues with downloading and/or installing Firefox.

---

GeckoDriver

The command to install geckodriver within ubuntu was error prone:

!apt install firefox-geckodriver

Here are the detailed steps:

• Browse to the geckodriver releases page. Checkout the compatible version of GeckoDriver for your platform and download it as follows:

  wget https://github.com/mozilla/geckodriver/releases/download/v0.24.0/geckodriver-v0.24.0-linux64.tar.gz
  

• Extract the file with:

  tar -xvzf geckodriver*
  

• Make it executable:

  chmod +x geckodriver
  

• Add the driver to your PATH so other tools can find it:

  export PATH=$PATH:/path-to-extracted-file/.

Firefox

The latest version of Firefox is always available as a security updates in all supported releases of Ubuntu and a normal update will install it. You need to enable the security or you need to update the repositories (e. g. Software & Updates -> Updates). You need to enable the Security by default but better to check if the package manager doesn't updates Firefox by default.

You can find the detailed steps in:

Update

Selenium Client Driver page mentions:

• Supported Python Versions:

  Python 2.7, 3.4+
  

• But the list on selenium 3.141.0 page includes only:

  • Python :: 2.7
  • Python :: 3.4
  • Python :: 3.5
  • Python :: 3.6

So possibly Python 3.7 is still not supported and you may have to downgrade to a relevant version.
