Daniel's solution in Comment #9 solved the issue for me when I today upgraded from Kubuntu 13.10 to 14.04.
As of April 6th, the akonadi-server package 1.12.0-0ubuntu1 still triggered the exact GID issue as was reported in comment #8. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to akonadi in Ubuntu. https://bugs.launchpad.net/bugs/1290717 Title: akonadi 1.11.80 fails to start Status in Akonadi - The PIM Storage Service: Unknown Status in “akonadi” package in Ubuntu: Confirmed Bug description: akonadi fails to start since the update from 1.11.0 to 1.11.80 Full description in upstream bug report: https://bugs.kde.org/show_bug.cgi?id=331867 To manage notifications about this bug go to: https://bugs.launchpad.net/akonadi/+bug/1290717/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
