on launchpad cannot change error report to private

Thank you for taking the time to report this issue and helping to make Ubuntu better. Examining the information you have given us, this does not appear to be a bug report so we are closing it and converting it to a question in the support tracker. We appreciate the difficulties you are facing, but it would make more sense to raise problems you are having in the support tracker at https://answers.launchpad.net/ubuntu if you are uncertain if they are bugs. For help on reporting bugs, see https://help.ubuntu.com/community/ReportingBugs#When%20not%20to%20file%20a%20bug. There is also a vibrant support community available at http://askubuntu.com and you might consider asking your question there.

There is a small frame on top right hand side 'This report is public', to edit the status click on the yellow button with the tiny pencil. Your example Bug #789200

Regarding apport-collect.
Quote:
<Additionally, when prompted to give apport-collect permissions for Launchpad you will need to give it at least the ability to "Change Non-Private" data as it will be adding information to your bug report.>

Bug reports which aren't submitted via apport (ubuntu-bug) usually are missing log files hence there will be a request to run apport-collect <bug-number> in order to sufficient triage a bug.
