Selenium WebDriverException issue - python, cannot start browser both in Chrome/Firefox

I have the following script that makes use of selenium for authentication process.
I'm on Ubuntu 20.04 LTS, the computer was reformatted in the past few days, the same script worked before, from reading other threads I suspect that this has to do something with the root user/privileges.
I've tried both Firefox (geckodriver) and Chrome (chromedriver), here's what I did:
Chrome:
from selenium.webdriver import Chrome
from selenium.webdriver.chrome.options import Options
import chromedriver_autoinstaller
chromedriver_path = chromedriver_autoinstaller.install()
browser = Chrome(executable_path=chromedriver_path)
The error:
Traceback (most recent call last):

browser = Chrome(executable_path=chromedriver_path)

(unknown error: DevToolsActivePort file doesn't exist)
(The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
Firefox:
from selenium.webdriver import Firefox
import geckodriver_autoinstaller
geckodriver_path = geckodriver_autoinstaller.install()
browser = Firefox(executable_path=geckodriver_path)
The error:
Traceback (most recent call last):

Also in the geckodriver.log:

Error: no DISPLAY environment variable specified
I've made sure that my chrome is installed in the default folder, tried to use options such as --no-sandbox, tried to set binary location to where chrome is, did not work.
I've installed chrome in its default path on Linux.
I've tried with the --no sandbox option
I've tried specified the binary path by setting `options.binary_path = '/path/to/google-chrome'
I've installed Xvfb on my machine
I've tried downloading the chromedriver and geckodriver manually and adding them to the path (after placing in /usr/local/...)

Cannot run Firefox (geckodriver) properly from PyCharm python console

So i use PyCharm 2018.2.3, geckodriver 0.20, Firefox 63.0 and Python 3.6.5 in it for my Selenium auto-tests.
What I try to do in Python Console to run the driver:
from selenium import webdriver
profile = webdriver.FirefoxProfile()
profile.accept_untrusted_certs = True
wd = webdriver.Firefox(executable_path="C:\\Users\\user\\geckodriver.exe", firefox_profile=profile)
So the geckodriver runs in a new window. Then I ususally write
url = "https://website-address.com/"
wd.get(url)
But this time I get the message:
Previous command is still running. Please wait or press Ctrl+C in console to interrupt.
And then in like a couple of minutes geckodriver exit with these messages in log:
Traceback (most recent call last):
File "<input>", line 4, in <module>
File "C:\Users\user\project\venv\lib\site-packages\selenium\webdriver\firefox\webdriver.py", line 170, in __init__

raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: newSession
Please help me to understand what is going on and how to fix it.

I was having the same problem and was fixed after I update the geckodriver to v0.21.0

So I've opened an issue on geckodriver github (https://github.com/mozilla/geckodriver/issues/1369), which was closed by a developer and I got an actual answer here in another similar issue: https://github.com/mozilla/geckodriver/issues/1305 - they've released a new version of geckodriver which fixed everything.
P.S. I'm almost absolutely sure I had no issues with my firewall.

Selenium fails to start Chromedriver - Ubuntu 16.04, Python 3.6.3

from selenium import webdriver
browser = webdriver.Chrome()
browser.get('http://www.google.com')
It never actually reaches this and fails with:

I have tried EVERY thread I can find and no solutions are working. I'm not sure if this is because it is a python 3.6 problem?

Did you try giving the chrome webdriver path directly inside the parenthesis?
Same code works perfectly on my windows machine.
I have set environment variables, else i need to provide the path directly.

Selenium Firefox 56 webdriver via geckodriver results in error: Can not connect to the Service

I am using geckodriver for Firefox and I'm running Python 3 with Selenium. This is my code in the file script.py:
from selenium import webdriver
browser = webdriver.Firefox()
browser.get('http://www.google.com')
Once I run it with python3 script.py with my terminal, it launches Firefox but simply doesn't load the page, nor does it insert the link in the address bar. My geckodriver is installed at this location: /usr/local/bin/geckodriver.
After waiting for about a minute, I get the following error:
Traceback (most recent call last):
File "script.py", line 3, in <module>
browser = webdriver.Firefox()
File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/firefox/webdriver.py", line 154, in __init__

raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: connection refused
I already searched a lot for fixes but none of them worked.
After I realized, I was using Firefox ESR instead of the normal one, I switched to the normal Firefox version and faced this problem:
Traceback (most recent call last):
File "script.py", line 3, in <module>
driver = webdriver.Firefox(executable_path=r'/root/Downloads/firefox-56.0.1/firefox/firefox')
File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/firefox/webdriver.py", line 144, in __init__
self.service.start()
File "/usr/local/lib/python3.5/dist-packages/selenium/webdriver/common/service.py", line 102, in start
raise WebDriverException("Can not connect to the Service %s" % self.path)
selenium.common.exceptions.WebDriverException: Message: Can not connect to the Service /root/Downloads/firefox-56.0.1/firefox/firefox

Which version of Selenium/Geckodriver/Browser are you using?
Anyway, do you set the executable_path:
driver = webdriver.Firefox(executable_path=r'pathTo/geckodriver')
?
EDIT
If you are using:
Selenium version = 3.6.0
Geckodriver version = 0.19.0
Firefox version = 52.4.0
Your problem is Firefox. From GeckoDriver releases, is recommended Firefox 55.0 (and greater).

python bindings for selenium returns in exception when initiating a Firefox webdriver object

When on windows I want to give a try with the webdriver extension for selenium, I get an error. I installed the python bindings like on the installation page. And then I try to to just the following:
from selenium import webdriver
browser = webdriver.Firefox()
Firefox (15.0) is opened and after that an exception occurs:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

selenium.common.exceptions.WebDriverException: Message: ''
I tried the same without webdriver, with the 1.0 api and then I can open Firefox and go to a specific page, but with the webdriver case I do not have any luck. Has anyone a clue what I do wrong ?
My OS is Windos 7, 64 bit version.
I also tried the same with the latest python bindings from version control, but that has the same error.
