Package: consolekit
Version: 0.4.1-4
Severity: important
I recently upgraded my Dell workstation at work from Lenny to Squeeze.
Upon logging in with kdm 4:4.4.5-1 I get the following error dialog:
"Warning: Cannot open Consolekit session: Unable to open session:
Failed to execute programm /usr/lib/dbus-1.0/dbus-daemon-launch-helper:
Success"
This happens on every login not only on the first one (see
http://bugs.debian.org/562026). Also that launch helper is setuid root
(see http://bugs.debian.org/578203 and http://bugs.debian.org/569058):
m...@mango:~> ls -l /usr/lib/dbus-1.0/dbus-daemon-launch-helper
-rwsr-xr-- 1 root messagebus 39880 27. Jul 21:39
/usr/lib/dbus-1.0/dbus-daemon-launch-helper
I have the following in syslog:
Aug 4 09:22:59 mango kdm: :0[21127]: Cannot open ConsoleKit session: Unable to
open session: Failed to execute program
/usr/lib/dbus-1.0/dbus-daemon-launch-helper: Success
Aug 4 09:23:01 mango ck-launch-session: error connecting to ConsoleKit
When I click "Ok" in the dialog, I still can login, but after some time I can
not lock the KDE session anymore, also Alt-F2 for running KRunner does not work.
When I logout and login again both functions work again.
When trying again with pressing Ctrl Alt Backspace when I see the
error dialog:
Aug 4 10:08:43 mango kdm: :0[10486]: Cannot open ConsoleKit session: Unable to
open session: Failed to execute program
/usr/lib/dbus-1.0/dbus-daemon-launch-helper: Success

Aug 4 10:08:47 mango kdm: :0[10486]: Cannot close ConsoleKit session: Unable
to close session: no session open
There is no console-kit-daemon process running.
To work around this issue I just started consolekit-daemon as root manually.
Then I didn't get an error message at boot.
I do have an Debian Squeeze/Sid/Experimental setup on my ThinkPad T42 setup
with same versions of ConsoleKit, DBUS and KDE, where this problem does
not happen. The only notable difference I can think of is that the
workstation as /home mounted via NFS while the ThinkPad has it as Ext4
filesystem. / is on an Ext4 filesystem is both cases. The NFS export is
mounted with root_squash, so that root cannot access it:

touch: cannot touch `/home/ms/testfile': Permission denied

That is the problem. dbus-daemon is not running under the correct gid (should be
120), so the dbus-daemon-launch-helper can't be executed)
Please read through Simon's excellent explanation at [1]. It seems, your problem
is a duplicate of #589979
A simple way to fix this, is to edit /etc/passwd and correct the gid of the
messsagebus user (change to 120), as dbus-daemon needs to run with git
messagebus.
It would be interesting to know, how you ended up with such a configuration.
Did you copy around /etc/passwd or /etc/group?
I'm closing this bug as a local misconfiguration error.
Regards,
Michael
