I use muon 5.7 on neon dev unstable. Under Wayland, when I open settings > Configure software sources I type my password, window to edit repositories settings is not opened and muon only updates the repositories index. Under X11 I can edit software sources.
`software-properties-kde` is an external application that Muon starts to let you configure software sources. This is being replaced by `software-properties-qt` as of Kubuntu 18.10, which is a more recent qt-only version and may work better in Wayland. You can try to start it manually from a shell. Does the problem still exist?
Hi Run software-properties-qt from terminal requires administrative rights. However it's impossible to run GUI with administrative rights on Wayland.
Now, that might be a problem! Muon is using kdesu to gain rights. What happens if you run `/usr/lib/kde4/libexec/kdesu software-properties-qt` from terminal? What with `pkexec software-properties-qt` (it should fail, though). If you are unable to start it manually it might be worth to report upstream at https://bugs.launchpad.net/ubuntu/+source/software-properties
`/usr/lib/kde4/libexec/kdesu software-properties-qt` no such file or directory 'pkexec software-properties-qt' asks for password and I get this error: QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root' qt.qpa.screen: QXcbConnection: Could not connect to display Could not connect to any X display.
The bug is now reported against software-properties-qt https://bugs.launchpad.net/ubuntu/+source/software-properties/+bug/1804887 There is a proposed (partial) solution attached. This bug report remains open because, if/when the change is applied to s-p-qt, we should stop using kdesu.
This problem persists. Operating System: KDE neon Developer Edition KDE Plasma Version: 5.15.80 KDE Frameworks Version: 5.56.0 Qt Version: 5.12.0
Still relevant: Operating System: Kubuntu 20.04 KDE Plasma Version: 5.18.4 KDE Frameworks Version: 5.58.0 Qt Version: 5.12.8
Currently "Configure software sources" window runs on Xwayland (I see xorg icon in task manager) and now I can edit software sources on Wayland session. :) Operating System: KDE neon Unstable Edition KDE Plasma Version: 5.22.80 KDE Frameworks Version: 5.83.0 Qt Version: 5.15.2 Graphics Platform: Wayland
