*** This bug is a duplicate of bug 1577712 *** https://bugs.launchpad.net/bugs/1577712
I believe that the root cause of this bug was actually bug 1577712 that we fixed in June (Yakkety) and July (Xenial, 16.04), so am marking this bug as a duplicate of that one. See bug 1577712 for details. For others subscribed to this bug, or otherwise believe they're affected by this issue: I see many comments above that I think are clearly due to unrelated issues, so this bug is probably not the one you want. ** This bug has been marked a duplicate of bug 1577712 mysql_upgrade is called twice concurrently on upgrade from 14.04 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1574168 Title: mysql-server-5.7.postinst fails with "Can't create database 'performance_schema'; database exists" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1574168/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
