Post-update klauncher errors

After installing a host of kf5 updates today I find that several applications complain when an action is invoked. As an example: invoking Evolution from a tray icon produces the error message “Unable to create io-slave. klauncher said: Error loading ‘/usr/lib64/qt5/plugins/kf5/kio/’.” This message occurs with other actions as well.

Hi @clh333 : did you log out/reboot after the update? Do these errors persist after a reboot?


After reboot the problem resolved itself. Thanks.



Then it’s probably one of those updates where a reboot is necessary for changes to take effect (an example of an update transaction that supports the behaviour of tools like gnome-software that now update on reboot).

You can install the tracer dnf plugin, which tells you what processes need to be restarted after a dnf transaction:

sudo dnf install python3-dnf-plugin-tracer
