Ubuntu :: Gksudo/gksu Silently Refuses To Do Anything
Jun 2, 2011
This comes at some point after installing GNS3 and Dynamips, which require administrator access as GUI's. Although, the first couple times I tried to run GNS3 as administrator, it worked fine. I do still receive the password prompt, whether running from the command line or the context menu. Note that GNS3 is the first application for which I've needed to run gksudo, so this may have been an issue before the above were installed, although I've always been able to run "Open as Administrator" in Nautilus and "Synaptic Package Manager," which now will not run either.
Running Ubuntu 10.10.

I am running a file server on Jaunty. It was a fresh install about a month ago and I have been having problems ever since. I connect external drives to the machine to do nightly backups. Lately, I have been using GParted (Gnome Partition Editor) to format the drives before using them as backups, as I keep a backup for every day of the week.
After using GParted a couple of times, it will stop working and I can't open it or any other application that needs root privileges. I can't use Gnome to mount drives anymore. I have to open Terminal and use the mount command to mount drives. Trying to start gparted or any other application, including nautilus from the Terminal using gksudo or gksu, I get the following error message:
Code:
gksudo nautilus
(nautilus:25353): nautilus-extension-gnome-mount-WARNING **: Cannot connect to system bus: org.freedesktop.DBus.Error.LimitsExceeded : The maximum number of active connections for UID 0 has been reached
(nautilus:25353): nautilus-extension-gnome-mount-WARNING **: Could not initialize hal context
[Code].....
Once the machine is rebooted, everything works fine until I run a few more privileged applications, then the applications stop working again and this whole process starts all over. The only way to fix the problem so far is to reboot the machine, which is completely unacceptable.

I installed lubuntu 10.10 from a minimal netinstall. For some reason, the main menu entry for synaptic package manager uses gksu instead of gksudo at the beginning of the command, as revealed by right-clicking the entry, then clicking "properties". This, of course, precludes the ability to access the program unless you're among the few who have activated the root user account. That's a problem in and of itself, but it's been recognized elsewhere. However, after I fixed the command and clicked "ok", nothing changed. I opened up the little properties menu again and it was gksu, as though I hadn't fixed the command.
The properties window is a mysterious little program called lxshortcut. I suspect that if I run lxshortcut using sudo, then the changes I make will actually stick. Problem is, I don't know how to find the actual location of the main menu's SPM shortcut/launcher-thingy. Nor are there any clear instructions on how to use lxshortcut in terminal. I flailed about with my best interpretation of vague instructions, but to no avail.
I downloaded alacarte (which is, of course, intended for gnome), and I got the software sources entry to show up in the list, but nothing else in the program responded when I clicked. The whole experience in alacarte was weird and unhelpful and somehow I've outright removed the menu entry for synaptic. And that's fine, I barely use it anyway, but Software Sources also has the same gksu problem, and I actually use that one. So how do I change the command associated with one of the preferences in the lxde/lubuntu main menu?

I'm a Linux noob. I'm using Karmic on a laptop with 1.5GB RAM and same as swap partition. Generally I'm happy with the mem usage. I have MySQL, SVN, Apache/PHP/xdebug, firefox w/ dev addons, Eclipse PDT and, of course, my music :) running at the same time, generally ok. I have the System Monitor's mem display on the top bar (dunno proper name) and can watch usage increase. Also the swap file's often only 100 - 300 megs.
However... from time to time I notice that as the programs' mem use gets close to 100% in the little sys monitor display the HD thrashes for 5 - 10 mins, after which some progs have silently crashed. AFAIR it always involves Eclipse (so maybe I should post on their boards), but not only. This last time I lost VLC and therefore my music. Obviously losing your music's far more important than losing some coding, so that's why I'm trying to resolve it now:)
I'm running Munin on my system (tho not because of this issue) and took a look at mem usage immediately before it happened. Here's the pic - you can see the sudden drop as the two progs (only AFAIK) closed on the very right side of the image. I'm not a guru here and am not sure if there's much to infer. I know some recommend 2xRAM for swap, but max committed was only 2.29 compared to potential 3, so that shouldn't be a problem? In fact the swap file never got large at all AFAICT. (Btw swappiness = default = 60.)

After updating recently VLC does not play audio or video, and it does not complain about not being able to do so, even when running from terminal.
The version is VLC media player 1.0.6 Goldeneye.
I have tried resetting the preferences.
I don't know how to troubleshoot any further..

I tried installing Ubuntu 9.10 using both Ubuntu Desktop CD and the Netbook Remix on a EEEPC 1005HA with an external CD drive.
In both cases I don't get any graphical interface during the installation. The CD is apparently installing everything silently, without letting me change anything on the way, and then it gets stuck.
The only screen I get is the first one, with the options to "try Ubuntu" or "install Ubuntu".
What's going on?

I am running the testing version and am fully up to date. When I try to run evolution, I get the following errors in a terminal. When I launch it normally, I don't see any messages, it just never loads.
$ evolution code...
What can I do to debug this and get it working again?

I am working on a bash script which among its operations creates directories using the mkdir command. However, when the directory already exists mkdir mentions that in the command line output.
Is there any way I can make mkdir silently overwrite any existent directory? (no messages in the output). For the same price, could it be done with other commands such as cp or mv?

Using sendmail, I am trying to setup a catchall address to silently discard spam mail sent to undefined users. I don't want to bounce a reply for "no user" as this often goes back to munged or innocent addresses.
I have a number of domains, so my virtuser table currently looks rather like this:
Code:
The last line is the "catchall" which is intended to ensure that any undefined users from either my_domain.com or my_domain.co.uk is forwarded to the non-existent "catchall" user account. Note that all mail sent to my_domain.com is passed across to my_domain.co.uk at the very start so all the following rules should apply to messages received at both domains. (Both of these domains appear in the
Being non-existent, I setup the following rules in the access data table:
Code:
This way, if I send an email to 'user1@my_domain.com' it is received and delivered to user1@my_domain.co.uk, but if I send an email to 'rubbish@my_domain.com' it *should* be received and silently discarded.
Unfortunately what actually happens is the server responds with:
Now, (just for testing), I made "catchall" an alias for the "postmaster" account and the mail was then received and delivered into the postmaster mailbox. So I know the virtuser rule is working. The account "catchall", however, is not being silently dropped as desired in either configuration.

When I try to open Transmission I get a message: "Couldn't open "/home/shai/.config/transmission/lock": Permission denied", and the only way to open it is by using gksudo.
I read on another thread that I need to delete that file, but the file doesn't exist.
What should I do?

Firefox 3.1 beta 3 won't load. When I open the application, the little bouncy icon bounces, and the task manager shows "Firefox Web Browser", but this only stays this way for about 15 seconds then just goes away. No error or anything.
I've had this identical problem when I try to open certain programs with Wine too. Is there some place I can find a detailed error report on these failures?

gksudo nautilus sets the background to default (Because nautilus is rendering the desktop) I set the gconf key to stop it rendering the desktop, but this only affects the icons. How can I get it to give me back my background? Edit: Fixed the desktop (--no-desktop option on nautilus command) - need to find how to kill the nautilus process automatically when I close it.

On Linux Mint, there is this theme called WildMint, looks somewhat like an older Ubuntu Studio theme. Anyway, I have been trying to find how to get it to work on Ubuntu instead of Mint. It is nowhere to be found on Gnome-Look and I've tried to search everywhere for it. Also, I've tried just copying the folder from /usr/share/themes but I just get errors even when running Nautilus under gksudo.

This occurred sometime in the past couple of days, perhaps because of an update that I just blindly accepted or due to some tinkering of my own. But for some reason, my gksudo never remembers the password I put in there anymore. When I sudo in a terminal it remembers no problem, and my sudo-via-terminal also responds to the "timestamp_timeout=x" variable in /etc/sudoers as it should. But does gksudo have it's own "/etc/sudoers" file where you can override the caching period for the password or does it reference the regular /etc/sudoers also?

I tried "gksudo nautilus", and it didn't work! When the root window pops-up, it isn't there! I would like to delete this annoying file so that i can see my whole desktop.

I am trying to use sudo but it prompts that the password is wrong.
When I try to use gksudo everything is fine. I also can use su - without a problem.
I tried to add my user to sudoers and it seemed to work as you can see here:
Code: Select allronel : sudo root adm cdrom floppy audio dip video plugdev users netdev lpadmin
but it did not change the situation.

I'd like to be able to run gksu (i.e. the default windowed authentication) without a password. I tried to find this on the wiki and here on the forums but wasn't able to find anything. I've allowed 'sudo' to run without a password:
Code:
<username> ALL=NOPASSWD: ALL
for my username but this has no effect on 'gksu'. As I am the only user on my machine and I have to enter a password on login

I can enter my password just fine to log into the system, and using sudo from a terminal also works, but "gksu" does not. It tells me my password is incorrect. That means Synaptic doesn't work unless I "sudo synaptic" from the terminal. Anyone else happen to encounter this yet, or is it just me? I started with a clean install of Kubuntu 10.10, which I later installed ubuntu-desktop over and then removed. Would that possibly make a difference here?

Every time I try to open Nautilus it requires root permission even if I don't use commands like gksudo.
I launch it from docky's bookmarks applet, requires root.
Use a command like "nautilus /home/harvey" it still requires root.
Adding the file browser launcher to docky doesn't even LAUNCH nautilus.
But launching file browser from gnome-panel works O_O.
But I never use gnome-panel, so I'd like to be able to launch it from docky and commands and stuff without root permission.

I have this issue on both Ubuntu and Lubuntu 11.04 64-bit on 2 different machines. I have not tested 32-bit.
When I run synaptic or update-manager it presents me with gksu, not gksudo as it previously did in previous Ubuntu releases, no matter how many times I try it will not accept my password.
I have even given it command line arguments to print the password to the terminal and it's correct.
I have found a workaround - by running gksu-properties and changing the mode from su to sudo it will now display gksudo and accept my password.
However, I want to know why it won't accept my sudo password for the su and gksu commands? There are no error messages which are outputted, the gui just says incorrect password.

I've been having a problem with administrative apps all the way from last years' distros, and in 10.04-x64 it's still here.
When i launch an application that needs gksu, it simply hangs waiting for a gksu window that never shows up.
If i launch another administrative app, it hangs as well.
When i look at the process list, i get a lot of gksu instances, all sleeping.
if i kill those processes, the mentioned apps resume with an authentication error
But if i use a terminal and type sudo <app>, it hangs for a few seconds, then prompts for password and it works fine.
I don't know why it works so badly, but it needs to be fixed soon, many new users will surely find this very frustrating.
I run ubuntu 10.04-64bit on a AMD-Athlon-x2
