Arch Linux

Please repost your sudoers file (it's empty)

Oh, I haven't noticed that. Now it should be OK...

Works over here.

are you in wheel?

Yes, I'm, but group wheel hasn't got administrator priveleges.

1. Did the latest update (1.7.3-1) fix your problem; it fixed some tty related problems (tty_tickets etc.)?
2. Does sudo (the cli command) work?
3. Does gksu work if you use it in su mode (run gksu-properties and change the mode)?

1. No, it's still the same.
2. Yes, of course.
3. No, I doesn't work in any.

For me gksu sudo mode doesn't work either with libgksu 2.0.12. I have /apps/gksu/sudo-mode = true in gconf. The problem is gksu asks for the root password instead of the users. Downgrading libgksu to 2.0.8 or building 2.0.10 solved it for me.
edit: gksu also downgraded to 2.0.2-1 of course.

Could you write, how I should do it?

Can anyone report this bug to gksu authors?

gksu is kinda deprecated
http://www.nongnu.org/gksu/index.html

gksu is being replaced by gksu PolicyKit, please take a look at http://live.gnome.org/gksu.

How can I use gksu PolicyKit?

Kurt: Why not just run gksudo command if you wish to use gksudo instead of gksu?
It works very well with the current packages in repo, provided you use the new sudoers.pacnew file (replace the old one, and edit the new one to your liking). Still, strange that this is needed.

Bah, I hate PolicyKit, it is about as much fun as SElinux. :/

It will soon be to much of a hassle to setup anything yourself without spending much more time on it than I (and most other people) like.

Tried with sudo-1.7.4.p2-1 libgksu-2.0.12-2 gksu-2.0.2-2 - gksudo now accepts my password but still does not run the command.
output of gksudo --debug terminal :

sudo: sorry, a password is required to run sudo

Obviously that can not work because of the -n switch. So this is clearly a bug in how sudo is called IMHO. After downgrading to gksu 2.0.2-1 and libgksu 2.0.8-1 it works and i get this output:
No ask_pass set, using default!

With my libgksu 2.0.10 package it works too and i get a similar output without the -n switch.
edit: make this a bit shorter

Meanwhile i found this in the gentoo bug tracker: http://bugs.gentoo.org/show_bug.cgi?id=290733
They use 01_revert_forkpty.patch from debian to solve this. With the patch applied libgksu 2.0.12 works again as expected here.

Hi there, I've applied the patch from gentoo, and modified the (attached) PKGBUILD for extra/libgksu .

I'm a bit new to arch so don't know how to submit my source package.

Can someone give this to the package maintainer or point me in the right direction to get it included in the next updates?

Oh yeah, and I tested it. It works on my system (famous last words).

@Gert (naguz)
On my system gksudo is simply a symlink to gksu (I did not do that, it already was). Is there another package that supplies just gksudo?

@Doug Penner (DarwinSurvivor)
They are the same program. Run gksu-properties to choose whether it uses sudo or su by default.

Indeed they seem to be the same program and gksudo is symlinked to gksu. However, running gksu asks for my root password, while gksudo asks for my password (like sudo). Strange indeed. I assume it is supposed to be this way, though - makes sense to me.

Anyway,it works here after the latest upgrade, hope it isn't a one-time thing this time!

You mean the update for sudo? I just got it and it worked...just one time. So it doesn't seem fixed yet.
