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

[Chris Halse Rogers]

Hello Erich, or anyone else affected,

Accepted kdesu into jammy-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/kdesu/5.92.0-0ubuntu1.1 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
jammy to verification-done-jammy. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-jammy. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

** Changed in: kdesu (Ubuntu Jammy)
       Status: In Progress => Fix Committed

Bug description:
  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.

  [Test Plan]

   * 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.

  * Confirm that the application authentcate and launch as successfully
  as in previous releases.

  [Where problems could occur]

   * 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.
