Description Jakub Schmidtke 2012-02-26 07:00:34 UTC 
Version:           unspecified (using KDE 4.8.0) 
OS:                Linux

I just installed apper, and I am unable to install any new packages using it.
It just says "Waiting for authentication", and stays like that for a long time.
I started investigating further, and when I try to install anything using
pkcon from packagekit the same thing happens - it just says
"Waiting for authentication", shows a moving progress bar
and nothing else happens.
When I kill /usr/lib/kde4/libexec/polkit-kde-authentication-agent-1,
run /usr/lib/polkit-gnome/polkit-gnome-authentication-agent-1
and try to use pkcon again, the authentication dialog pops up
and I am able to authenticate.
Can anybody confirm whether it's a problem with my setup,
or the polkit-kde is simply broken?
I'm running these versions of relevant packages:
dbus 1.4.16-1
dbus-core 1.4.16-1
dbus-glib 0.98-1
dbus-python 0.84.0-1
kdelibs 4.8.0-3
kdebase-workspace 4.8.0-2
polkit 0.104-1
polkit-gnome 0.105-1
polkit-kde 0.99.0-2
polkit-qt 0.103.0-1packagekit 0.6.21-2
packagekit-qt2 0.6.21-2
apper 0.7.1-2


Reproducible: Always

Steps to Reproduce:
run 'pkcon install package'


Actual Results:  
pkcon waits for authentication and doesn't get it, nothing shows up, no popup windows, no activity visible

Expected Results:  
dialog window shows up, asking for password

I figured out what was wrong.
I had QT_NO_GLIB=1 set in the environment (in /etc/profile.d/ script).

I still think that this is an issue.
If it is impossible to get polkit agent working without glib loop events,
then it should not run at all. Or at the very least display an error...

I meant that unseting QT_NO_GLIB makes the problem go away.

Confirming, it ignores impossibility to authenticate silently when QT_NO_GLIB is set.

simply needs
   setenv("QT_NO_GLIB", "0", true);
before creating the Q*Application instance (in main.cpp or however the source is organized)
