SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 114 using latest Chromium v116.0

Trying to run Selenium with Chromium (through ChromeDriverManager) on a Linux machine.

Error message:

selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 114

Chromium info:

$ chrome --version
Chromium 116.0.5826.0
$ which chrome
/usr/local/bin/chrome

Python code:

from selenium import webdriver
from selenium.webdriver.chrome.service import Service as ChromiumService
from webdriver_manager.chrome import ChromeDriverManager
from webdriver_manager.core.utils import ChromeType

chromium_driver = ChromeDriverManager(chrome_type=ChromeType.CHROMIUM).install()
driver = webdriver.Chrome(service=ChromiumService(chromium_driver))
driver.get("http://www.justinbieber.sucks")
driver.quit()

The error message makes it obvious that this is a version/compatibility issue (between Chromium and ChromeDriver), but there doesn't seem to be a ChromeDriver for Chromium 16.0 yet. Also, I can't for the love of God find a download link for Chromium 14. ChromeDriverManager is not helping a lot either.

This error message...

selenium.common.exceptions.SessionNotCreatedException: Message: session not created: This version of ChromeDriver only supports Chrome version 114

...implies that there is a version incompatibility between [tag:chromium] and ChromeDriver version.

This usecase

The latest ChromeDriver being v114.0.5735.90 you have to downgrade the Chromium browser version accordingly.

Solution

To download, install and use a specific version of Chrome / Chromium on Linux you need to follow the relevant steps from the Download Chromium page:

> Downloading old builds of Chrome / Chromium Let's say you want a build
> of Chrome 44 for debugging purposes. Google does not offer old builds
> as they do not have up-to-date security fixes.
>
> However, you can get a build of Chromium 44.x which should mostly
> match the stable release.
>
> Here's how you find it:
>
> Look in https://googlechromereleases.blogspot.com/search/label/Stable
> updates for the last time "44." was mentioned. Loop up that version
> history ("44.0.2403.157") in the Position Lookup In this case it
> returns a base position of "330231". This is the commit of where the
> 44 release was branched, back in May 2015.* Open the continuous builds
> archive Click through on your platform (Linux/Mac/Win) Paste "330231"
> into the filter field at the top and wait for all the results to XHR
> in. Eventually I get a perfect hit:

> Sometimes you may have to decrement the commit number until you find
> one. Download and run!
> * As this build was made at 44 branch point, it does not have any commits merged in while in beta.
>
> Typically that's OK, but if you need a true build of "44.0.2403.x"
> then you'll need to build Chromium from the 2403 branch. Some
> PortableApps/PortableChromium sites offer binaries like this, due to
> security concerns, the Chrome team does not recommend running them.
