[Bug 1965439] Re: applications can no longer launch when called by kdesu

Fri Jul 8 11:16:22 UTC 2022

** Description changed:

- 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.
+ kdesu fails to authenticate with sudo from Jammy.

- Steps to recrate:
+ See upstream bug: KDE bug: https://bugs.kde.org/show_bug.cgi?id=452532

- 1) Open Plasma-discover
- 2) Go to Settings
- 3) Under click on "Software Sources"
- 4) Attempt to enter password
+ Examples: Kubuntu driver manager, 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.

- Expected: Software properties opens
+ On entering the correct password authentication is refused, stating that 
+ possibly an incorrect password has been entered.

- Actual: Pkexec keeps asking for password.
+ It appears that kdesu fails to cope with the sudo config change in this 
+ commit:

- ------
+ https://salsa.debian.org/sudo-
+ team/sudo/-/commit/59db341d46aa4c26b54c1270e69f2562e7f3d751

- Earlier description:
+ kdesu was fixed in Debian with:

- The driver manager for both Ubuntu Studio and Kubuntu can no longer
- launch due to some updated security measures in PolicyKit.
+ https://tracker.debian.org/news/1330116/accepted-kdesu-5940-2-source-
+ into-unstable/

- 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 issue can be worked around by adding /etc/sudoers.d/kdesu-sudoers
+ with the contents

- 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.
