STEPS TO REPRODUCE 1. connect to a wi-fi network 2. click on the plasma-nm applet 3. click on the connected wi-fi network and then click on its "Show network's QR Code" button OBSERVED RESULT nothing happens EXPECTED RESULT network's QR Code is shown SOFTWARE/OS VERSIONS Operating System: KDE neon Unstable Edition KDE Plasma Version: 5.27.80 KDE Frameworks Version: 5.240.0 Qt Version: 6.5.0 Graphics Platform: Wayland
This is working for me; I suspect a packaging bug. Can you kill plasmashell, run it in a terminal window, and print the console output that appears when you click on the "Show network's QR Code" button?

> qml: Cannot create QR code component: file:///usr/share/plasma/plasmoids/org.kde.plasma.networkmanagement/contents/ui/ShareNetworkQrCodePage.qml:14 module "org.kde.prison" is not installed Yep, Neon packaging bug. The Prison framework isn't installed, or is being installed from its Qt5 version, or isn't available in some other way.
kf6-prison was lacking quite a few deps. now fixed and nm applet has been recompiled and confirmed to show qr code.
