Raspberry Pi Installation issue

Hi!
I'm trying to install instaPy on my raspberry and I followed your [guide](https://github.com/InstaPy/instapy-docs/blob/master/How_Tos/How_to_Raspberry.md) in order to do it, but unfortunately I'm running into this error when I try I run `sudo python3 quickstart.py` and I don't know what to do:
`InstaPy Version: 0.6.8
._. ._. ._. ._. ._. ._. ._.
Workspace in use: "/root/InstaPy"

% (self.path, return_code)
selenium.common.exceptions.WebDriverException: Message: Service /usr/local/bin/geckodriver unexpectedly exited. Status code was: -11
`

Thanks for the help!

The report points to How_Tos/How_to_Raspberry.md and the sudo python3 quickstart.py entry point; begin by comparing the guide with the reported Python 3.7 and geckodriver traceback. Done means the documented Raspberry Pi installation path runs quickstart.py without the reported WebDriverException, with any required guidance reflected in the guide.
