ok. The "bug" is reproducible. It has happened on every time i have installed ubuntu 16.04 (all iterations). It is quirky because if you do a reboot three times in a row, the error message goes away and apparmor allows mysql to start without any errors. on the same machine with exactly the same hardware and configurations, 16 fails, 15 fails, 14 fails half the time, and 12 runs. Every failure is a combination of apparmor and mysql. My test system is to do 4 fresh installs and configurations on each version of ubuntu. If this is not a bug in the operating system, then I have been using the wrong definition of what a bug in software is for the last 42 years. It is a bug if it happens at all whether you can repeat the case or not. Unless I send you my machine, you cant reproduce it or we wouldnt be exchanging messages. Bottom line, I am having a problem with Ubuntu and the way apparmor interacts with other parts of the operating system. Since Im not a linux programmer, nor do i have the time to chase this rabbit down the hole, I have two choices. One, get windows server, or two, get a new machine. Thank you for your time you have graciously given me. I do appreciate it. Im frustrated at the issue and not you. please forgive me for being rude or offending you. It was not my intention.
