Confirmed facing this bug. I managed to use the .desktop file workaround
for Discover, but it does not seem to work for Muon.

Bug description:
  See description below. As the driver manager is done inside software-
  properties-qt, it's basically the same bug, but now it's affected by
  something we can't exactly get into the mechanism of: plasma-
  discover's "Software Sources" link.

  Steps to recrate:

  1) Open Plasma-discover
  2) Go to Settings
  3) Under click on "Software Sources"
  4) Attempt to enter password

  Expected: Software properties opens

  Actual: Pkexec keeps asking for password.

  ------

  Earlier description:

  The driver manager for both Ubuntu Studio and Kubuntu can no longer
  launch due to some updated security measures in PolicyKit.

  The original behavior was that systemsettings would open
  /usr/bin/ubuntustudio-driver-manager (or /usr/bin/kubuntu-driver-
  manger) via pkexec, which would then open software-settings-qt.
  Unfortunately, the new behavior does not act correctly to pkexec and
  pkexec does not see the user as available in the sudoers file.

  The only way around this was to pass "export DISPLAY=:0" inside the
  appropriate driver manager executable with the command "sudo software-
  properties-qt". The KCM itself needs to execute the driver-manager via
  xterm, which then prompts for a password. It's ugly, but it works.

  I will attach a debdiff for the kubuntu-settings package.
