So this is fun. With a fresh install of
#Linux, and immediately installing Kontact, Akonadi, and therefor Kontact and Kmail, no worky. All the possible fixes I could find dont work. Arch, Manjaro, same issue.
It can't tell the mysqld version, and can't find the dbus...
I rely very heavily on Kontact.
What does work is fresh installing an older version of Linux and not updating. Thats really not a fix.
