Title:
sudo apport-kde is in a different design (stripped
XDG_CURRENT_DESKTOP)
Status in sudo package in Ubuntu:
Confirmed
Status in sudo source package in Jammy:
New
Bug description:
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 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
[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
