Do you have a backtrace?

Comment 2 Andreas Hencke 2020-05-28 21:25:09 UTC

Not yet, because of the backtraces were marked as useless so I didn't saved one.
Right now akonadi crashed again, this time dr. konqi didn't start aswell.
I tryed to start akonadi via Konsole and got this output:

andreas@rex-PC:~$ akonadictl stop
Akonadi is not running.
andreas@rex-PC:~$ akonadictl start
org.kde.pim.akonadicontrol: Service org.freedesktop.Akonadi.Control.lock already registered, terminating now.
Error: akonadi_control was started but didn't register at D-Bus session bus.
Make sure your system is set up correctly!

I'll report a backtrace asap!

Backtrace from Dr Konqi

Comment 4 Andreas Hencke 2020-05-29 10:22:49 UTC

This is a backtrace from my other Desktop machine. It has a MSI A320m motherboard and a Ryzen5 2400G CPU. / and /home are splitted as in the other machine. One point might be  importandt: On this machine I installed Kubuntu 20.04 in January from a daily iso, Up to the official release of Kubuntu 20.04 akonadi was working prperly without an issue.
