Thank you for your report. I believe this has happened because you have a locally modified /etc/apparmor.d/usr.sbin.mysqld. The one we ship has "/etc/mysql/** r" which includes /etc/my.cnf.migrated.
If you still think this is a bug in Ubuntu, please explain, provide exact steps to reproduce and then change the bug status back to New. Thanks! ** Changed in: mysql-5.7 (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1610765 Title: mysql server fails to start due to faulty apparmor profile To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1610765/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
