Can reproduce when booting kubuntu-22.04-desktop-amd64.iso in Virtualbox and on my main installation of Kubuntu 22.04.
Happens both on X11 and Wayland session. When I try to go to software-sources via Discover or Muon on the live image (where no user password is set), it simply doesn't launch. Terminal output of 'pkexec software-properties-qt': qt.qpa.xcb: could not connect to display qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found. This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem. Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland- xcomposite-glx, xcb.
