.desktop files can not start apps with kdesu

[Harald Sitter]

-install synaptic
-start via kickoff

KDEInit could not launch '':
Could not open library '/usr/lib/x86_64-linux-gnu/libkdeinit5_'.
Cannot load library /usr/lib/x86_64-linux-gnu/libkdeinit5_: (/usr/lib/x86_64-linux-gnu/libkdeinit5_.so: cannot open shared object file: No such file or directory)

(upstream bug somewhere in kio, notmart has a review for it pending somewhere)

Synaptic should probably start using pkexec instead of kdesu like it does for the regular gtk frontend.

[Leszek Lesner (leszek-lesner)]

In general pkexec can be used for every application. Would make the password prompt more consistent also.

[Rohan Garg (rohangarg)]

Already being discussed upstream on KDE Frameworks Devel, there are going to be focus stealing issues as mentioned on [1] if we use pkexec everywhere. So this needs to be solved in pkexec first before moving forward.

The bigger issue is that neither DBUS_SESSION_BUS nor DISPLAY is forwarded through pkexec which prevents KUniqueApplications (and their KF5 counterpart one presumes) from starting as uniqueness is implemented through dbus and auto-starting a session dbus at least on X11 requires DISPLAY to be set (not that I know why).

Patch for Synaptic

[Chris J Arges (arges)]

Rejected upload as it contains extra debian/patches/series file. Please fix this and reupload, thanks.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Timo Aaltonen (tjaalton)]

Please add the SRU header as mentioned on https://wiki.ubuntu.com/StableReleaseUpdates

[Bruno Patri (bruno666-deactivatedaccount)]

Possible workaround :

sudo ln -s /usr/bin/kdesudo /usr/bin/kdesu

[MaXo (mahmood-188)]

had the same issue.

Bruno's workaround did the trick! Thanks!
