According to the error message "officeHome must exist and be a directory" I don't thing you have configured the right folder. Can you tell me the value of the "system.openoffice.path" configuration property? You can see it in Administration (tab) > Configuration. Also can you post here the contents of that directory.
We have tested LibreOffice with the last Ubuntu released and works pretty well.
