Did you also see the specific error message "Can't create database 'performance_schema'; database exists" ?
We saw this when upgrading from Ubuntu 14.04 to 16.04 due to a race condition between the new postinst and old upstart script (which would still be running until the host is rebooted and switched to systemd). This was fixed as per https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1577712 (not yet released), but if you're still seeing the same issue after a reboot then it might be a separate problem. -- 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
