Instead of engaging in discussion, you seem to want to attack. Please leave your hostility at the door. I was not complaining. I appreciate that you do not understand. I explained my reasons quite clearly. And the community has explained its reasons quite clearly. I had not appreciated that the legal advice was from Nokia. I do not want to go to add an external repository. My reasons for that are to do with integrity and security of my device. Not rocket science, is it?
