SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** STEPS TO REPRODUCE 1. Go to Settings > Configure Software Sources 2. Fill in password to access 3. OBSERVED RESULT I'm getting a permissions denied prompt after several attempts EXPECTED RESULT Permission granted SOFTWARE/OS VERSIONS Linux/KDE Plasma: Kubuntu 22.04 KDE Plasma Version: 5.24.4 KDE Frameworks Version: 5.92.0 Qt Version: 5.15.3 ADDITIONAL INFORMATION Other places I'm able to to use the graphical sudo (don't know the name of the KDE name) without issue. I'm even able to edit repositories with Discover. For some reason, Muon isn't able to recognize my password when trying to administer repos. Muon is able to install/uninstall packages without issue. Also able to apt update using it as well. Just seemed really odd just this one place wouldn't work, so I thought I'd put a bug report in for it.
Muon is no longer maintained, please switch no a supported alternative like https://apps.kde.org/discover/ or the package manager native no your system. Sorry for the inconvenience.
