Im currently facing some issue on my jenkins docker agent, trying to run the test cases there.
Im getting this error:
- Cache folder (/home/jenkins/.cache/selenium) cannot be created: Permission denied (os error 13)
- SessionNotCreatedException: Message: session not created: Chrome failed to start: exited normally.
- (session not created: DevToolsActivePort file doesn’t exist)
- (The process started from chrome location /usr/bin/chromium is no longer running, so ChromeDriver is assuming that Chrome has crashed.)

Im installing the latest versions of these libraries:
robotframework
selenium
robotframework-seleniumlibrary
robotframework-robocop
robotframework-libtoc
robotframework-pabot
robotframework-browser
babel
requests
pycountry
xmltodict
names
Pillow
PyPDF2
pdfplumber
The failure appears in the Open Browser kwd from SeleniumLibrary trying to run cases in headless.
After I downgraded these libraries, it started working again:
robotframework==6.0.2
selenium==4.9.1
robotframework-seleniumlibrary==6.1.1
Could really use some support in this dept.
Thanks beforehand

Hi Redon,
I would suggest this is your issue:

This is not a robot framework issue, but rather a permissions / setup issue on your test machine.
You should give the user running the test create permissions (or ask your sys admin for help with that) to create that path.
Am I correct that the user running the test is called jenkins? If so it seems odd that they don’t have create permissions in their own user folder? Perhaps your admins have been a little too aggressive on the security policy?
Dave.
