Cannot get Akonadi to start

I have a fully updated TW KDE system and wanted to try Kmail but I cannot get Akonadi to start. The messages are


stuart@Tumbleweed:~> akonadictl start

org.kde.pim.akonadictl:    done.

now this is a vanilla TW install and I have made no changes to Akonadi prior to this and have not previously been using anything which required Akonadi to be running. I do not have MySQL installed but I thought it was supposed to use MariaDB? Can anyone please suggest what I have missed here?

Note I also see


2021-01-12T10:02:30 [WARN ] default: Connecting to deprecated signal QDBusConnectionInterface::serviceOwnerChanged(QString,QString,QString)

in file Akonadi.error.

Maybe this is related?

Well I simply deleted all the Akonadi stuff in my local folders for my user and started it again and it all works now. I had not used anything before so I had nothing to lose.

In ‘~/.local/share/akonadi/’ was/is there a link pointing to ‘/run/user/1000/akonadi/’ ?

I do believe there was such a link when I was having problems.
