I was facing the same error:
session not created: This version of ChromeDriver only supports Chrome version 75
...
Driver info: driver.version: ChromeDriver
We are running the tests from a computer that has no real UI, so I had to work via a command line (CLI).
I started by detecting the current version of Chrome that was installed on the Linux computer:
$> google-chrome --version
And got this response:
Google Chrome 74.0.3729.169
So then I updated the Chrome version like that:
$> sudo apt-get install google-chrome-stable
And after checking again the version I got this:
Google Chrome 75.0.3770.100
Then the Selenium tests were able to run smoothly.
