I want to update from Version 9.5.8 to 9.5.9.
My Steps:
  1. Login to SSH to the Webserver, change the correct directory
  2. Download the new Version 9.5.9 from get.typo3.org/9
  3. unzip the tar.gz
  4. Correct the link to new version
  5. Open the /typo3/install in Webbrowser
  6. Clear all Caches
  7. Check for new changes - no available - Version 9.5.9
  8. Check the Backend and I gets the error "Cannot use object of type stdClass as array"
  9. Go back to 9.5.8
