The old debian-start script used by upstart runs mysql_upgrade, checks for crashed tables and checks for passwordless root accounts (printing a warning if one is found).
In 5.7, d/postinst will secure passwordless root accounts with unix socket auth and run mysql_upgrade, and mysql_upgrade itself will check for and fix any crashed tables, so this script is no longer needed. Additionally this could cause mysql_upgrade to be executed by both upstart and postinst on upgrades, causing various errors. The solution is to change the script in 5.7 to a no-op ** Changed in: mysql-5.7 (Ubuntu) Status: Triaged => In Progress -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1577712 Title: mysql_upgrade is called twice concurrently on upgrade from 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1577712/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
