Hi, I have various programs crashing during bootup and afterwards due to “no qt platform plugin could be initialized”. How can i fix that? Programs include baloo-file-extr, polkit-kde-authentication-agent, kalendarac, nextcloud, kglobalacceld and others

Here is a typical error message:

Jul 30 10:37:38 ZeroD kcminit_startup[9645]: qt.qpa.xcb: could not connect to display
Jul 30 10:37:38 ZeroD kcminit_startup[9645]: qt.qpa.plugin: From 6.5.0, xcb-cursor0 or libxcb-cursor0 is needed to load the Qt xcb platform plugin.
Jul 30 10:37:38 ZeroD kcminit_startup[9645]: qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.

                                             Available platform plugins are: minimal, wayland-egl, wayland, linuxfb, vkkhrdisplay, minimalegl, eglfs, offscreen, xcb, vnc.

I am using KDE/Wayland.

Cool, I might not be able to make much sense of it but it will help others out who know to advise you a lot better
EDIT - Semi wondering if deleting your cache and logging out and back in would help this sounds sort of like the weather widget issue the other day? (NOTE this is just a guess to be safe back up instead of delete - could also try with a new user)

The meta packages plasma-meta and kde-applications-meta were not installed. After installing those, the error messages are gone.

Good to see you figured it out, there may be a more minimal way but this is a great solution to it
