I recently upgraded to Fedora 44 and part of the upgrade includes KDE Gear 26.04.0 and Kontact apps getting upgraded to 6.7.0. Following this update, I am unable to interact with any Akonadi-based apps. I get an error saying “A required background service is not operational”. If I click the “Details…” button, nothing appears. Running akonadiconsole in terminal, I see the following output:
Please register the custom scheme 'cid' via QWebEngineUrlScheme::registerScheme() before installing the custom scheme handler.
org.kde.pim.akonadicore: ""
org.kde.pim.akonadicore: Job error: "" for collection: QList()
How can I get Akonadi stuff to start working again?
