Title:
  Software Sources/software-properties-qt privilege escalation not
  accepting password

Status in plasma-discover package in Ubuntu:
  Confirmed
Status in software-properties package in Ubuntu:
  New

Bug description:
  1) lsb_release -rd
  Description:    Ubuntu Jammy Jellyfish (development branch)
  Release:        22.04

  2) package version - apt-cache policy pkgname'

  plasma-discover:
    Installed: 5.24.2.1-0ubuntu1

  software-properties-qt:
    Installed: 0.99.19

  3) expected to happen
  * In Discover: Settings > Software Sources
  * opens a privilege escalation dialogue
  * enter user password
  * software-properties-qt opens

  4) happened instead
  * In Discover: Settings > Software Sources
  * opens a privilege escalation dialogue
  * insert known-correct user password
  * **does not accept known-correct user password**

  # Additional Info
  Note: described behaviour is for a post 20.04->22.04 devel daily upgrade found during a QA Testcase. Behaviour exists, but has slightly different symptoms in a virgin live 22.04 daily session (see below)

  * launching from terminal works as expected
  sudo software-properties-qt

  ## process & errors - post 20.04->22.04 devel daily upgrade
  * running Discover from terminal
  	$ plasma-discover

  * Settings > Software Sources 
  gives error on terminal:
  > org.kde.kdesu: Daemon not safe (not sgid), not using it.

  * insert known-correct user password
  gives error on terminal:
  > kf.su: [ ./src/stubprocess.cpp : 225 ]  Unknown request: "stop"
  > end

  * close password window
  gives error on terminal

  > Usage: /usr/lib/x86_64-linux-gnu/libexec/kf5/kdesu [options] command
  > Runs a program with elevated privileges.

  > Options:
  >   -h, --help                 Displays help on commandline options.
  > [...]

  ## process & errors - live Kubuntu 22.04 daily

  similar behaviour, hoever password-asking window never appears.
  Terminal errors differ from above:

  * Settings > Software Sources 
  gives error on terminal:
  > org.kde.kdesu: Daemon not safe (not sgid), not using it.
  >
  > Don't need password!!
  >
  >kf.su: [./src/stubprocess.cpp : 255 ]  Unknown request: "ok"
