Title:
sudo apport-kde is in a different design (stripped
XDG_CURRENT_DESKTOP)
Status in sudo package in Ubuntu:
Fix Released
Status in sudo source package in Jammy:
Fix Released
Bug description:
[Impact]
Running ubuntu-bug as normal user has the correct theme (see
screenshots attached to bug #1881640), but running "sudo ubuntu-bug"
has a different, non-matching theme (see attached screenshot). This
applies to all Qt applications.
[Test Plan]
This problem can be reproduce by running a KDE application on Ubuntu
Desktop (GNOME):
1. Launch ubuntu-22.04-desktop-amd64.iso
2. Install apport-kde
3. Run: /usr/share/apport/apport-kde -f
4. Run: sudo /usr/share/apport/apport-kde -f
5. Compare both windows. They have different icons and font size.
Same result with KDE:
1. Use kubuntu-22.04-desktop-amd64.iso
2. Run ubuntu-bug -f
3. Run: sudo ubuntu-bug -f
[Where problems could occur]
Passing through an additional environment variable could lead to an undesired
side effect (if an application expect it not be be set when run as root). Since
this environment variable changes the code paths, it could reveal Qt bugs
related to running as root.
[Analysis]
Qt needs XDG_CURRENT_DESKTOP to be set to determine the correct theme,
but XDG_CURRENT_DESKTOP is not in the list of environment variables to
preserve (and not in env_keep in /etc/sudoers).
On other other hand, sudo preserves the DISPLAY environment variable:
$ sudo env | grep -Ev '^(LC|LS|SUDO|LANG|COLOR|TERM|PATH)'
XAUTHORITY=/run/user/1000/gdm/Xauthority
DISPLAY=:0
MAIL=/var/mail/root
LOGNAME=root
USER=root
HOME=/root
SHELL=/bin/bash
[Workaround]
Prevent sudo from dropping XDG_CURRENT_DESKTOP by running: sudo
XDG_CURRENT_DESKTOP=$XDG_CURRENT_DESKTOP /usr/share/apport/apport-kde
-f
