I got the same error log message when starting KMail after upgrading from Kubuntu 14.04 to 16.04. (Of course, something KMail-related getting broken in an update isn't surprising anymore, email being bleeding-edge and all . . . )
2017-01-08T02:29:26.960676Z 0 [ERROR] unknown variable 'innodb_additional_mem_pool_size=1M' 2017-01-08T02:29:26.960682Z 0 [ERROR] Aborting Checking mysql-global.conf I found: # memory pool InnoDB uses to store data dictionary information and other internal data structures (default:8M) # Deprecated in MySQL >= 5.6.3, removed in 5.7 (works in MariaDB) # innodb_additional_mem_pool_size=8M Note that not only is the innodb_additial_mem_pool_size already commented out in the existing version of the config file, its value is 8M, not the 1M in the log! Deleting the line entirely allowed KMail to start -- so far, so good. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to akonadi in Ubuntu. https://bugs.launchpad.net/bugs/1569651 Title: akonadi startup fails with unknown variable innodb_additional_mem_pool_size [Xenial 16.04] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/akonadi/+bug/1569651/+subscriptions -- kubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
