Created attachment 113356 [details] akonadi-selftest-report I had installed 'neon-useredition-20180614-1022-amd64.iso' within virtualbox. With Discover I installed Kontact then run it and got an error message from akonadi serlf-test. Status of the akonadi server is stopped. It look's like a missing folder. After making the folder '/home/.../.local/share/akonadi/db_data', the self-test runs without a message. And the akonadi server is running.
