Mageia forum

I installed package 'sudo' and this works fine at user terminal (after amending /etc/sudoers).
However, to use gui apps (like kwrite or kate), command 'kdesu' does not work (I assume neither would gksu, but I don't use gnome).

Code: Select all

bash: kdesu: command not found

If I use only 'sudo' for gui, eg., I get

Code: Select all

$ sudo kwrite /boot/grub2/custom.cfg
[sudo] password for .......
No protocol specified
kwrite: cannot connect to X server :0

(but that is to be expected)

Also checked that I have kdebase4 installed.
How can I get kdesu to work? Thanks.

ps: I'm on m3b4, but I don't suppose that makes any difference (but systemd...?).

kdesu has nothing to do with systemd, and also not with sudo.
Can't tell for cauldron, but in Mageia 2 kdesu comes with kdebase4-runtime, but the problem is it's not in $PATH.
E.g. i created a symlink to be able to use it easily:

[doktor5000@Mageia2 ~]$ ls -al /usr/bin/kdesu
lrwxrwxrwx 1 root root 29 Jan 19 18:59 /usr/bin/kdesu -> /usr/lib64/kde4/libexec/kdesu*

If you want to use sudo with GUI apps, you probably need to use sudo -E to preserve your environment variables.
This is the case since at least Mageia 1. I'm using an alias for that, works fine:

Code: Select all

[doktor5000@Mageia2 ~]$ alias sudo
alias sudo='sudo -E'

Thanks again for your response.

Yes, I think you're right.

kdebase4-runtime was also installed.

I did the above link and alias, unfortunately, I still could not get kdesu to work.

Code: Select all

ls: cannot access /usr/bin/kdesu: No such file or directory

but alias command has no error and I assume is performed.
I then use "ln" instead of "ls" thinking it might be a typo, but same error message.

doktor5000, this is not a show-stopper (meaning it is not a big deal as I can still go to root terminal "su -" and do my things there) but I want to thank you again for your help. Having sudo alone is a great utility itself and I was hoping to use kdesu as well.
Danke.

to create the link use

Code: Select all

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

Thanks alf,
but following results...

Code: Select all

ln: failed to create symbolic link ‘/usr/lib64/kde4/libexec/kdesu’: File exists

and I still cannot kdesu

Googling this gives an interesting find..

but honestly, I don't know what polkit is all about.
I also have Chakra (with systemd) and Kubuntu and both works with kdesu (kdesudo) at installation..

Thanks everyone, and as I mentioned, there's no need to sweat this.
Cheers!

[edit] sudoedit works....but I'd rather not.

try:

Code: Select all

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

@gohlip: Please don't mangle everything together.

1. sudo has no relation to kdesu, so the alias "sudo -E" is only for sudo, but you mentioned it together, when trying to get kdesu to work.
2. please show the output of the following command:

Code: Select all

ls -al /usr/bin/*kdesu*

3. If you post error messages, always post them together with the command that produced them.
4. sudo alone is not enough, in a graphical desktop session one often may need kdesu/gksu.

doktor5000, here goes...

Code: Select all

$ ls -al /usr/bin/*kdesu*
ls: cannot access /usr/bin/*kdesu*: No such file or directory


Cheers!

[edit]oops...I should use kdesu not kdesudo

Code: Select all

[pop@localhost ~]$ kdesu kate /boot/grub2/custom.cfg
bash: kdesu: command not found
[pop@localhost ~]$

thanks again.
Cheers!

Well, your last post is totally mixed up.

1. for the first command, try again with

Code: Select all

sudo -E kate /boot/grub2/custom.cfg

2. There's no kdesudo, only kdesu - kdesu is normally used inside a KDE session to start graphical apps (like systemsettings) and it should already be working there - try Alt+F2 and enter kdesu systemsettings
3. ls only shows files/directories/links, it does not create them. Look for tom's post how to create the symlink to make kdesu available in a terminal for your user.

Code: Select all

[pop@localhost ~]$ kdesu kate /boot/grub2/custom.cfg
bash: kdesu: command not found
[pop@localhost ~]$ sudo -E kate /boot/grub2/custom.cfg
[sudo] password for pop:
Fontconfig warning: "/etc/fonts/conf.d/50-user.conf", line 9: reading configurations from ~/.fonts.conf is deprecated.
Error: "/var/tmp/kdecache-pop" is owned by uid 1000 instead of uid 0.
kate(2457)/kdeui (kdelibs): Session bus not found
To circumvent this problem try the following command (with Linux and bash)
export $(dbus-launch)
KCrash: Application 'kate' crashing...
KCrash: Attempting to start /usr/lib64/kde4/libexec/drkonqi from kdeinit
sock_file=/home/pop/.kde4/socket-localhost/kdeinit4__0
[pop@localhost ~]$


As above, kate crashed.
Using Alt+F2 and enter kdesu systemsettings, it works.
GUI system settingss appears.
And so did "kdesu kate /boot/grub2/custom.cfg" at Alt +F2


Now, how to make this work at user terminal?

ps: doktor5000, thanks for your persistence.

Look for tom's post how to create the symlink to make kdesu available in a terminal for your user.

Missed his post in the "flurry" of quick successions of posts. Sorry Tom, missed your post altogether, and you're right spot on!

Code: Select all

$ sudo ln -s  /usr/lib64/kde4/libexec/kdesu /usr/bin/kdesu

works wonderfully!

Thanks to doktor5000, alf and Tom.
Great team! Cheers! Have a beer on me. Salute!
