[Bug 1965439] Re: [SRU] kdesu fails to authenticate with sudo from Jammy

[Rik Mills]

** Description changed:

  kdesu fails to authenticate with sudo from Jammy.
  
  See upstream bug: KDE bug: https://bugs.kde.org/show_bug.cgi?id=452532
  
  Examples: Launch Kubuntu driver manager from system setting, launching
  ksystemlog from the main menu, or trying to run krusader root mode
  option via its 'Tools > Start Krusader Root Mode' menu entry. Assuming
  that the current user is a member of the sudo group.
  
  On entering the correct password authentication is refused, stating that
  possibly an incorrect password has been entered.
  
  It appears that kdesu fails to cope with the sudo config change in this
  commit:
  
  https://salsa.debian.org/sudo-
  team/sudo/-/commit/59db341d46aa4c26b54c1270e69f2562e7f3d751
  
  kdesu was fixed in Debian with:
  
  https://tracker.debian.org/news/1330116/accepted-kdesu-5940-2-source-
  into-unstable/
  
  and fixed in kinetic with:
  
  https://launchpad.net/ubuntu/+source/kdesu/5.94.0-0ubuntu2
  
  The issue can be worked around by adding /etc/sudoers.d/kdesu-sudoers
  with the contents
  
  Defaults!/usr/lib/*/libexec/kf5/kdesu_stub !use_pty
  
  [Impact]
  
-  * Users are unable to authenticate to and launch applications via kdesu.
-  * This should be backported to restore functionality that users expect.

  * Confirm that the application authentcate and launch as successfully as
  in previous releases.
  
  [Where problems could occur]
  
-  * Examples.
+  * While this update only returns sudo to its default behaviour (used in
+ previous releases and virtually all other distributions) for kdesu, care
+ should be taken to test some other applications that seek root
+ permissions to confirm that no unexpected consequences occur.

** Changed in: sudo (Ubuntu Kinetic)
       Status: Confirmed => Won't Fix

** Changed in: sudo (Ubuntu Jammy)
       Status: Confirmed => Won't Fix
