I am getting this same error on one of my systems that too is running Fedora 14 x64 LXDE.  I would be willing to provide more information if requested.

--- Additional comment from Dan O'Brien on 2010-12-11 12:27:42 EST ---

Is this bug dead?  I've seen no follow up whatsoever.  And I'm still getting this error as is this other commenter.  HELLO. IS THIS THING ON?

--- Additional comment from Richard Shaw on 2010-12-14 21:01:27 EST ---

I'm getting the same error on two F14 x86_64 installs.

--- Additional comment from Richard Shaw on 2010-12-15 09:31:18 EST ---

I believe this was caused during an update and is not isolated to F14. I used LXDE as my desktop for my MythTV machine and I remember seeing an error like this pop-up at some point on F13 x86_64. I can't be sure if it was the exact same error as the system auto-started Myth and I never investigated it further since I was already planning a fresh install of F14.

--- Additional comment from Richard Shaw on 2011-01-03 13:41:08 EST ---

I think I found the problem. The solution is so go into "Preferences->Desktop Session Settings" and un-check "PolicyKit Authentication Agent" as LXDE runs it's own LXPolKit Authentication Agent.

--- Additional comment from Till Bubeck on 2011-01-04 02:38:06 EST ---

I can confirm, that the alert box is not shown anymore with the fix from comment #6. Additionally I do not see anything broken by disabling the PolicyKit Authentication Agent.

Thanks!

--- Additional comment from Richard Shaw on 2011-01-04 08:51:20 EST ---

I'm out of my league here but I'll ask a few questions...

Are the session "services" (for lack of a better description) DE dependent? If so, then I think PolicyKit Auth. Agent should be disabled for LXDE by default.

--- Additional comment from Christoph Wickert on 2011-01-08 06:13:08 EST ---

We need an agent but it does not matter which one this it. IMHO each desktop environment should use it's own default agent. The problem is that /etc/xdg/autostart/polkit-gnome-authentication-agent-1.desktop only contains "NotShowIn=KDE;" and lacks "LXDE".

I already suggested that change back in April 2010 on the desktop-mailing list [1] but the GNOME maintainers refused. Instead they suggested to hardcode the agent somewhere. This was part of the "PolkitAgentReorg" feature [2] that never happened.

IMHO this feature is useless: People should be free to use whatever agent they want. They still might want to use polkit-gnome in LXDE because it has more features (but also more dependencies). Xfce doesn't have xfce4-polkit or alike. We should not and we cannot decide for the users, we should focus on providing a reasonable default configuration that works out of the box and does not throw errors.

David, does that sound reasonable? Can I go ahead and make that NotShowIn change in polkit-gnome?

What I'd like to know from all you bug reporters: Is there anybody who did a fresh install of Fedora 14 or installed the F14 LXDE spin or did you all upgrade? If you upgraded, polkit-gnome was already installed and lxpolkit was installed in addition to it because it is a new package in F14. If you did a fresh install lxpolkit should have fulfilled the requirement for "PolicyKit-authentication-agent" (a virtual provides that is provided by lxpolkit, polkit-gnome and kdebase), so polkit-gnome should not have been pulled in. Something might have an explicit requirement for one or the other agent hardcoded, this would be a bug in packaging but then.

Last but not least I'd like to invite all LXDE users to join our Fedora LXDE mailing list at http://lists.fedoraproject.org/pipermail/lxde/
This is the right place to talk about issues like this one. I just found this bug by accident.

--- Additional comment from Dan O'Brien on 2011-01-08 08:05:30 EST ---

I did a fresh install of the F14 LXDE (64 bit) and encountered this problem.

--- Additional comment from Christoph Wickert on 2011-01-08 08:35:57 EST ---

OK, in order to find out what pulled in polkit-gnome
- please try to uninstall it with yum. If there are no deps and it will uninstall, you don't need to confirm. If there are deps, please tell us.
- please attach the output of rpm -qa --last to this ticket

Thanks for your help.

--- Additional comment from Susi Lehtola on 2011-05-06 12:45:58 EDT ---

I just got the same error in XFCE4 on a fresh install of F15.

--- Additional comment from Christoph Wickert on 2011-05-21 14:35:27 EDT ---

Can you give us more details, Jussi? What polkit agents do ypu have installed and which are running? Is gnome-shell installed? It ships yet another agent.

--- Additional comment from Gilboa Davara on 2011-05-27 10:37:48 EDT ---

Seeing the same with Fedora 15 / x86_64 / XFCE installed.
gnome-shell installed.
How can I check which polkit agents are active?

--- Additional comment from Christoph Wickert on 2011-05-27 10:47:34 EDT ---

Look at the files in /etc/xdg/autostart or ~/.config/autostart. 'ps -A| grep pol' also helps but I have no idea how the new agent that is included in gnome-shell is called.

--- Additional comment from Gilboa Davara on 2011-05-27 10:57:40 EDT ---

OK. I looked the xfce startup configuration and it had two polkit agents: LXPolKit and PolicyKit.

Disabling LXPolKit solved the problem.

--- Additional comment from Jos Vos on 2011-09-08 12:26:10 EDT ---

Where did you find this?  On F15 with all updates (and GNOME / LXE / Xfce installed) I get this error on every Xfce session.

--- Additional comment from Christoph Wickert on 2011-09-08 13:09:30 EDT ---

In the session properties. For LXDE this is lxsession-edit, for Xfce it is xfce4-session-settings and for GNOME is is in gnome-session-properties.

--- Additional comment from Jos Vos on 2011-09-12 09:38:23 EDT ---

OK, like Gilboa I had in my Xfce session autostart list both PolicyKit and LXPolKit enabled, so I disabled LXPolKit.

--- Additional comment from bob mckay on 2011-11-28 22:31:25 EST ---

Still present in F16. This is a bit of a disaster for server systems, because gnome and a lightweight such as lxde are both needed (most users seem to prefer gnome for local sessions; but in my experience gnome3 is pretty much unusable for remote sessions). Requiring users to disable a security feature (i.e. lxpolkit) seems to be asking for trouble down the line.

--- Additional comment from Christoph Wickert on 2011-11-29 03:35:00 EST ---

Bob, we are not asking anybody to disable a security feature but to decide which of the two programs that provide exactly the same functionality they want to use.

--- Additional comment from bob mckay on 2011-11-29 10:25:36 EST ---

Christoph, I know that's not what you're intending to do, and there's a strong possibility that I'm misunderstanding. But if people become accustomed to turning off lxpolkit on systems which have gnome installed, isn't there a high likelihood that they will think it is also the right thing to do on systems built with lxde only? And if the automatic loading of gnome-polkit ever gets disabled in a future version of fedora, won't the same problems arise even on systems built with gnome? My concern was that this falls into the human factors side of security, setting up a situation where users with limited knowledge are likely to default into unsafe practices.

--- Additional comment from Linux Zombie on 2012-01-11 12:18:38 EST ---

Long post incoming.. This really is an issue.  I created an account just to post this.  I've been scurrying the web off and on trying to find a solution to this.  I have done fresh installs of F16 but using Xfce (moved over from Ubuntu Unity = yuk).

Anyways, I can say that initially, it was working fine (fresh install) but at some point after installing other packages and updates, this broke.  Info:

- Fedora 16 Xfce spin 64-bit
- /etc/xdg/autostart/xfce-polkit-gnome-authentication-agent-1.desktop exists but not a ~/.config/... equivalent and contains:
    [Desktop Entry]

    Summary     : PolicyKit integration for the GNOME desktop
- xfce4-session-settings does have the check mark for "Policy Kit Authentication Agent

Last to mention, I "do" run vncserver and remote X into the box.

This last piece "might" shed some light.  When I had a GUI session on the "head" and a vnc client separate remote X session.  The PolKit would popup the root password prompt on the MAIN head's GUI when it should be asking on the vnc client remote session!  However, I changed the run-time boot to just multi-user (no initial gui on the "head").. that seems to have solved the issue temporarily (started getting the polkit prompt in the vnc clients), but then this stopped working again.. even without a "head" GUI.

My workaround is to not use the GUI firewall, Add/Remove Software, Software Update, etc.  Been just opening up a term window, su, then use yum (and firewall-tui).

--- Additional comment from Linux Zombie on 2012-01-11 12:44:09 EST ---

my error's slightly different.  If I try to run system-config-firewall, I get:

"org.fedoraproject.slip.dbus.service.PolKit.NotAuthorizedException.org.fedoraproject.config.firewall.auth: "

if I try to run gpk-application (Add/Remove Software), upon trying to install something, I get a slightly different error with this window:

"Authorization Failed - You have failed to provide correct authorization.  Please check any passwords or account settings."

before, I would get a prompt to enter the root password instead.

--- Additional comment from Fedora End Of Life on 2012-08-16 17:50:36 EDT ---

This message is a notice that Fedora 14 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 14. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained.  At this time, all open bugs with a Fedora 'version'
of '14' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this 
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen 
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we were unable to fix it before Fedora 14 reached end of life. If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora, you are encouraged to click on 
"Clone This Bug" (top right of this page) and open it against that 
version of Fedora.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:

That's a bit weird because lxpolkit isn't in mate comps group.
Can you attach the yum log of the groupinstall command?
yum history
yum history list <id>

Can you uninstall lxpolkit without removing a mate package?

MATE does not install lxpolkit.

What DE did you have installed before you installed MATE?

What is the exact command you used to install mate?

What is the output of "repoquery --whatrequires lxpolkit"?

Comment 4

Brian J. Murrell

2013-10-30 03:02:04 UTC

Hrm.  So the things you gave me to investigate have shed some light.  I thought I was sure lxpolkit came with MATE but I was mistaken.  It seems to have come as a dependency of blueman:

$ repoquery --whatrequires lxpolkit
blueman-0:1.23-6.fc19.x86_64

which is a dependency of cinnamon:

$ repoquery --whatrequires blueman
blueman-nautilus-0:1.23-6.fc19.x86_64
bluez-0:4.101-6.fc19.x86_64
bluez-0:4.101-9.fc19.x86_64
cinnamon-0:2.0.3-1.fc19.x86_64

This dependency of cinnamon on blueman seemed to have happened when I got cinnamon-1.9.1-19.fc19.x86_64.

What is interesting though is that I was able to remove just lxpolkit and nothing else which is not surprising when you notice that blueman does not depend on lxpolkit:

2013-10-30 09:07:00 UTC

You can savely remove blueman because it doesn't work anymore in f20.
Blueman isn't ported to bluez5 and upstream is death.
A alternative for mate user is to use bluedevil from kde.

Sorry, i missread your fedora version, blueman do work in f19.

Comment 7

Rex Dieter

2013-10-30 11:55:59 UTC

blueman Requires: PolicyKit-authentication-agent

which has multiple providers including lxpolkit, mate-polkit, gnome-polkit, kde-polkit

(not sure why repoquery doesn't list them all)

> But then why does repoquery --whatrequires lxpolkit say blueman requires it?

Because it defaults to enabling option --alldeps, which means it checks whether anything depends on stuff _provided by_ lxpolkit. Nothing requires the package name "lxpolkit":

  $ repoquery --exactdeps --whatrequires lxpolkit
  $

The dependency is only on the "PolicyKit-authentication-agent" capability of lxpolkit. 

  $ repoquery --whatrequires PolicyKit-authentication-agent
  blueman-0:1.23-7.fc20.x86_64

  $ repoquery --whatprovides PolicyKit-authentication-agent
  mate-polkit-0:1.6.0-2.fc20.x86_64
  mate-polkit-0:1.6.0-2.fc20.i686
  lxpolkit-0:0.1.0-6.fc20.x86_64
  polkit-gnome-0:0.105-5.fc20.x86_64
  polkit-kde-0:0.99.1-2.20130311git.fc20.x86_64

Compare with:

  $ repoquery --whatrequires polkit-gnome
  blueman-0:1.23-7.fc20.x86_64
  cinnamon-session-0:2.0.1-1.fc20.x86_64
  xfce4-session-0:4.10.1-2.fc20.i686
  xfce4-session-0:4.10.1-2.fc20.x86_64

  $ repoquery --exactdeps --whatrequires polkit-gnome
  cinnamon-session-0:2.0.1-1.fc20.x86_64
  xfce4-session-0:4.10.1-2.fc20.i686
  xfce4-session-0:4.10.1-2.fc20.x86_64

"blueman" is gone in the second query. The first query only found that polkit-gnome may resolve a "PolicyKit-authentication-agent" requirement.


> (not sure why repoquery doesn't list them all)

Because the query is specifically about what depends on lxpolkit.
