Install it anyway?', with 'Proceed' and 'Cancel' buttons 3. click on 'Cancel' button OBSERVED RESULT the installation is not aborted, 'Cancel' button remains in the upper right-corner, it becomes greyed out if clicked, then Discover gets stuck and I need to kill it.

Install it anyway?' SOFTWARE/OS VERSIONS Operating System: KDE neon Unstable Edition KDE Plasma Version: 5.26.80 KDE Frameworks Version: 5.99.0 Qt Version: 5.15.6 Graphics Platform: Wayland
