I also have this issue. After applying the fix from comment #4, it fails on test #10: Akonadi control process not registered at D-Bus. Details: The Akonadi control process is not registered at D-Bus which typically means it was not started or encountered a fatal error during startup. I also upgraded from Kubuntu 14.10 to 15.04 (Beta 2 approx. a month ago) Full log: ------------------------------------------------------- Akonadi Server Self-Test Report =============================== Test 1: SUCCESS -------- Database driver found.
