I am setting up a robot test-environment. I can't get robot to start the firefox browser.

My environment: Lubunto (linux) 20.04 Python 3.8.10 Firefox 93.0

I installed:

$ pip install --upgrade robotframework-seleniumlibrary
$ pip install webdrivermanager 
$ webdrivermanager browser firefox

I added my .local/bin and .local/share/WebDriverManager/bin to PATH

Installed versions: Robot Framework 4.1.2 webdrivermanager 0.10.0 geckodriver 0.29.0

I created a file helloworld.robot:

*** Settings ***
Library  SeleniumLibrary

*** Test Cases ***
Testcase HelloWorld
    Open Browser  https://www.knmi.nl/home  firefox

Running this robot test fails on: WebDriverException: Message: Service geckodriver unexpectedly exited. Status code was: 64

There is a file geckodriver-1.log containing: geckodriver: error: Found argument '--websocket-port' which wasn't expected, or isn't valid in this context

Does anyone have a sugestion how to solve this?

Helio gave the solution: order webdrivermanager to install 0.30.0:

webdrivermanager firefox:v0.30.0

Please not the 'v' before 0.30.0. Without it webdrivermanager cant find that version.

Most likely is outdated version of geckodriver when managed by webdrivermanager.

Try to install manually the latest, 0.30.0.
