Just found the root cause. I leave mysql service disabled (using it only for some testing).
So 'invoke-rc.d mysql start' is just a no-op in that case and since post-install script assume that the service is enabled and running upon start, it fail all time it require mysqld running! No more mysql_upgrade error 11 with mysql.service correctly enabled! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1574017 Title: mysql error during upgrade from ubuntu 14 - 16 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/1574017/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
