[SOLVED] KDESU not working

[dkeith]

I have somehow managed to break kdesu so that it doesn't work.

kdesu exists in /usr/lib64/kde4/libexec/kdesu

I followed the instructions in https://forums.mageia.org/en/viewtopic.php?f=7&t=4760&p=33271&hilit=kdesu#p33271, but that didn't solve it for me.

output from running kdesu in a gnome-terminal root session:

Code: Select all

# kdesu
Fontconfig warning: "/etc/fonts/conf.d/65-google-droid-sans.conf", line 61: Having multiple values in <test> isn't supported and may not work as expected

kdesu(29247)/kdeui (kdelibs): Session bus not found
To circumvent this problem try the following command (with Linux and bash)
export $(dbus-launch)
KCrash: Application 'kdesu' crashing...

sock_file=/root/.kde4/socket-DAVIDOPTIPLEX9010/kdeinit4__0

[1]+  Stopped                 kdesu


If I become root in terminal by typing 'su -', kdesu works. But that's not where I need it to work. In my X session, typing Alt-F2 and typing 'kdesu ' + an application name, like gnome-terminal or kate, does nothing.

Obviously I did something to break kdesu, how do I get it back?

Oh, and if I click on the mcc/drakconf icon, I still get prompted to enter the root password and mcc starts fine.

Thanks.

Why do you want to run kdesu from a root session? The point of kdesu is to avoid opening a root session, it's a replacement for that.

Please show the output of

Code: Select all

rpm -V kdebase4-runtime

[dkeith]

Code: Select all

# rpm -V kdebase4-runtime


...produces no output.

Can you please run /usr/lib64/kde4/libexec/kdesu in a terminal as normal user as you would via Alt+F2?
Like

Code: Select all

/usr/lib64/kde4/libexec/kdesu dolphin

dkeith, maybe it's something more basic...

First you need to install "sudo"

Code: Select all

# urpmi sudo

Then you need to include user in /etc/sudoers

Code: Select all

{user}    ALL=(ALL)    ALL

Finally

Code: Select all

# ln -s  /usr/lib64/kde4/libexec/kdesu /usr/bin/kdesu


Hope this helps. Cheers.

ran it as a non-root user... unfortunately since I'm out of the office I had to VPN in to the office from my home Ubuntu 13.04 machine, then ssh in from gnome-terminal, then run the command:

Code: Select all

$ /usr/lib64/kde4/libexec/kdesu dolphin

kbuildsycoca4 running...


...and dolphin came up in my X environment in Ubuntu from the remote host. So that's probably not a true test.

The best that I can do apart from that is test it when I'm back in the office.

Thanks.

Thanks for the reply, gohlip. I've already set up my non-root user in sudo, and have already symlinked the kdesu script when following the instructions here:

https://forums.mageia.org/en/viewtopic.php?f=7&t=4760&p=33271&hilit=kdesu#p33271

So I don't think that is going to solve it. But I appreciate the ideas. It was worth a try.

What do you mean by more basic? kdesu is an alternative to sudo, they have nothing to do with each other ...
kdesu can use sudo if you configure it to do so, but setting up sudo will not change anything about kdesu.

Can you back up what you said?

[doktor5000]

kdesu is a frontend to enable execution of (GUI) applications as root, it uses su to do that. You don't need sudo for that, and by default kdesu doesn't use sudo.

sudo is an alternative for su, and has to be configured to allow users to launch root commands.
Check e.g. https://wiki.archlinux.org/index.php/sudo#kdesu

[gohlip]

Thanks for the link, referencing your link...."Fortunately one can tell kdesu to use sudo instead of su."
Also see links below..
http://www.linfo.org/kdesu.html
http://techbase.kde.org/Projects/kdesu#sudo

[doktor5000]

What's your point? Both links explain exactly what I was telling you, did you actually read them thoroughly?

[gohlip]

Yes, correct. kdesu has nothing to do with sudo unless you set it to do so.
And Debian/Ubuntu has defaulted to do so with kdesudo.
Mageia's kdesu, if set up, is with su.
(Mageia's sudo, if set up, is with sudo.)
Cheers, doktor5000. No issue here. I am clear. Thanks.

Ok ran the above command from a gnome-terminal session, ultimately the KDE Crash Handler popped up, here's the developer info:

Once I ran - as a normal user -

Code: Select all

export $(dbus-launch)

, then ran the above command, it ran fine.

[doktor5000]

Seems your dbus installation/setup as normal user is broken. Should be started with X login via /etc/X11/xinit.d/30dbus

Every time I've come in to my KDE desktop I would get the notification on the KDE panel/system tray/notification app that dbus failed to start. Can I just do a urpmi --replacepkgs dbus-whatever?

[doktor5000]

You can try, but will probably not help. We've had some users reporting the same issue in german forum since Mageia 2, but root cause is still unknown, and it's not reproducable elsewhere: https://forums.mageia.org/de/viewtopic.php?f=18&t=1301

You may want to remove draksnapshot, which sometimes seems to be involved in the problem.
Also take a look at those bugs: https://bugs.mageia.org/show_bug.cgi?id=5622 and https://bugs.mageia.org/show_bug.cgi?id=9326

EDIT: Which medium did you use to install Mageia, and is that a fresh installation, or an upgrade/import of old settings?

[dkeith]

I uninstalled draksnapshot as part of the troubleshooting of another issue, am now using luckybackup.

I installed MGA2 as I recall, and upgraded it to MGA3.

Thanks.

[doktor5000]

You could try with a freshly created user, if the issue persists.

[dkeith]

Ok, I think I've got it solved now, thanks for the advice. In cleaning up my luckybackup files on a test backup I must have deleted some system files. I reinstalled > 400 pkgs, and now kdesudo seems to be working.

Thanks again.
