Sorry, but I have no idea. A similar bug was reported some time ago by Rick Mills https://bugs.kde.org/show_bug.cgi?id=382611 in Neon and Artful, but I cannot reproduce it.
The authentication is handled by PolicyKit (PolkitQt1). It has it's own configuration on how to authenticate and authorize the user. But as it has already been said, it is more likely that the authentication window is just hidden behind something else. After a little time the authentication window expires and the error message is shown. ** Bug watch added: KDE Bug Tracking System #382611 https://bugs.kde.org/show_bug.cgi?id=382611 -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to muon in Ubuntu. https://bugs.launchpad.net/bugs/1714820 Title: Muon refuses to elevate to superuser for package install To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/muon/+bug/1714820/+subscriptions -- kubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
