Hi, after an update kontact doesn't start.
After starting akonadiconsole and in there Server restart i get this here:

MySQL server log contains errors.
Details: The MySQL server error log file '<a

Further:
Test 10:  ERROR
--------

Akonadi control process not registered at D-Bus.
Details: The Akonadi control process is not registered at D-Bus which
typically means it was not started or encountered a fatal error during
startup.

and the last error message:
Test 13:  ERROR
--------

No resource agents found.
Details: No resource agents have been found, Akonadi is not usable
without at least one. This usually means that no resource agents are
installed or that there is a setup problem. The following paths have
been searched: '/usr/share/akonadi/agents'. The XDG_DATA_DIRS
environment variable is set to
'/home/sgo/.local/share/flatpak/exports/share:/var/lib/flatpak/exports/share:/usr/local/share:/usr/share:/var/lib/snapd/desktop';
make sure this includes all paths where Akonadi agents are installed.

So i don't know the details of how they work together, and maybe there
is only the mysql error and the others are gone, if this could be
solved.

Does someone have a hint for me?
