Ubuntu :: Failed To Execute Child Process Skype-wrapper?
Apr 6, 2011
Just figured this one out and thought I'd post it here in case it helped someone else. Skype just upgraded itself from 2.1 to 2.2. After upgrading it didn't start, and I got the message
"failed to execute child process skype-wrapper" First test out if skype runs from the command line, by running this in a terminal
Code: skype & If it runs, you're good to go: simply right click on the menu, locate your entry for skype and change the command to launch it from skype-wrapper to skype. The reason for this is that in the 2.1 version, skype needed a script called skype-wrapper to set some varibles before start up. Upgrading removes the script, but failed to update the menu entry.

There seems to be a common solution to get the webcam working with Skype - rather than launching with Skype you launch with LD_PRELOAD=/usr/lib32/libv4l/v4l2convert.so skype - so far so good. When I do this I get the error There was an error launching the application. Details: Failed to execute child process "LD_PRELOAD=/usr/lib32/libv4l/v4l2convert.so" (No such file or directory). But I do have that directory and file on my system.
A ubuntu community doc talks about the terminal command sudo ld.so.preload-manager when I action this I get sudo ld.so.preload-manager /usr/lib/libv4l/v4l1compat.so [sudo] password for dad: sudo: ld.so.preload-manager: command not found

I am trying to create a launcher in Fedora 13 which will run a simple script named proj4a. I run this script from the command line as follows: $ /home/enowak/proj4a >/home/enowak/proj4a_out where proj4a is an executable file in my home directory and the output goes into a file, proj4a_out, in my home directory. Everything works fine.
I created a launcher called Proj4a and in the command field I entered the following: '/home/enowak/proj4a >/home/enowak/proj4a_out' When I click on the launcher it comes back with the following: There was an error launching the application. Details: Failed to execute child process "/home/enowak/proj4a >/home/enowak/proj4a_out" (No such file or directory) I can't for the life of me figure out what is wrong here. Does anybody see what I'm missing?

I just upgraded Xubuntu from 10.04 LTS to 11.04 and I am no longer able to mount removable media from the "places" menu. The message I get:
"Failed to execute child process exo-mount (No such file or directory)"
I assume some wrapper process is attempting to execute a program called "exo-mount," but no such program exists anywhere in the repositories, according to a search with apt-file. The "exo-utils" package used to contain exo-mount, but the program no longer exists in that package.
Mounting from within Thunar works fine.

I just installed a program and do not know what is causing this error. When I run it from the applications menu I get the following error "Could not launch 'FirstClass Client' :Failed to execute child process "/opt/firstclass/fcc" (No such file or directory)". I opened up a terminal and looked at the location. The file is there. I do not know much at all in this area but do not understand why this error is occurring.

I am running F11 and I want to mount an FTP, but when I try to connect to an ftp server using Places -> Connect to Server, or the bookmarks I made I get an error that says 'Failed to execute child process "/usr/lib/firefox-3.5/firefox" (No such file or directory)' and sometimes it mounts anyway, but most the time it doesn't, and it never connects to the folder I asked it to, I just have to open the mount and navigate to it. I figure this happened because Firefox upgraded to 3.5.1 and the folder is now /usr/lib/firefox-3.5.1/firefox, but I don't know how to update this so that it looks in the right location.

Consider the following code:
Code:
int main()
{
int i=0;
pid_t pid;
for(i=0;i<2;i++)
[code]....
I get the following output:
Parent: chid_pid=4356 i=0 parent's pid=4355
This is child 4356 i=0
This is child 4357 i=1
[code]....
I can observe instead of two children(as I expect) processes there are three. This is because child process 4356 creates its own child. Why all the messages of the type "This is child X i=Y" are concentrated one under another? How exactly fork works? Is affected by the fact that I have a dual-core processor?

I have a doubt about signals in C programming. I have done this little program to explain it. It creates a child process with fork and, when the child ends, receives the SIGCHLD signal and wait for its termination.Ok, quite easy, BUT when I execute this code the SIGCHLD signal is received twice, first as an error (returns -1) and the second one to finish the child process.I don't understand the meaning of the first received signal. Why is it generated? Is the code wrong? (if you add the SIGINT and press Ctrl+C during the execution it also receives two signals instead of one)
Code: #include <stdio.h>
#include <unistd.h>
#include <string.h>

I am troubleshooting something and I got this problem.
If I do "pstree -p"
It shows,
Code:
[code]....
However, it does NOT show up in "ps -elf"
Code:
ps -elf | grep soffi
0 S whho 7734 1 0 80 0 - 36435 - 11:14 pts/2 00:00:03 /usr/lib/openoffice/program/soffice.bin -splash-pipe=5
0 S whho 7833 7759 0 80 0 - 751 - 11:21 pts/3 00:00:00 grep soffi
I was wondering if 7735, 7736, 7737, 7743 were really processes. Then I checked /proc, I could cd to /proc/7735, /proc/7736, etc, but I could not ls them out. I looked at the man page of "pstree", it says,
Code:
Child threads of a process are found under the parent process and are shown with the process name in curly braces, e.g.
icecast2---13*[{icecast2}]
So, what does all this mean? Does it mean that 7735, 7736, 7737, 7743 are just threads but not processes? If so, why could I cd to /proc/<id> but not see them in "ps -elf".

I just updated from 9.04 to 9.10 (it's a long story, and I still can't go beyond 2.30).The update got rid of WICD, which is what I used and installed network-manager. Network-manager was not working at all, so I uninstalled it again and installed WICD. I could connect perfectly and had no problems.However, now the computer hangs during boot, saying that init can't start network-manager. I assume that something went wrong during the uninstalling process, since it wasn't updated.
This is the message: init: Failed to spawn network-manager main process: unable to execute: No such file or directory.
So how do I update it or manually change it so it stops requesting network-manager?

My machine is dual booted with Fedora 14 and RHEL 6. (I have only installed Red Hat because I am studying for RHCE). Just now I tried to install the Banshee player on my Red Hat OS. I ran various scripts inside the directory to see what really happens and after I ran the 'Makefile.in' file my terminal froze. It displayed '/bin/ not found'Then i restarted my computer and I got the following messages:
init: Failed to spawn readahead-collector main process: unable to execute: no such file or directory
init: Failed to spawn rcS main process: unable to execute: No such file or directory
init: Failed to spawn readahead main process: unable to execute: No such file or directory
[code].....
I tried run level 1 and run level 3 but I get the same error messages.
PS: My Fedora 14 installation is working fine.

Code:
#include <stdio.h>
#include <unistd.h>
#include <signal.h>
[code]....
Description of what the code does or what i intended to do:
1. Created a child process from parent process using 'fork()'
2. Sent a signal 'SIGALRM' from child process to parent process using 'sigqueue' function.
(The Third parameter of 'siqueue' function contains the message (message msg) which the child process wants to send to the parent process.'msg' is a stucture instance containing a) pid of child and b) string) 5. Print the 'msg' sent by child process inside the signal handler function 'sig_action_function' of the parent process I am getting some junk value when this line is executed
Code:
printf("%d
",msg->cpid);
I expected to get the pid of child process, which the child process sent to parent process through the signal.

I have a root process (on linux) that forks a child and the child process then drops privileges by doing a setuid() to a normal user. After the child setuid()'s, it is of course impossible for it to gain root again by itself. But since the main process is still running as root, i was wondering if there was a simple/smart way of getting the root-master-process to elevate the child back to root (or maybe just to another non-privi uid). Is there some way to do a setuid() on another pid? or maybe something can be done through /proc/<pid>/? Killing the child is not an option (because its what it does today and im trying to find a smarter way). (The program is apache2's mpm-itk worker and the "child" is the actual apache2 process serving a page.)

I work with social sciences and I really need to use "R". R is a program used for statistics and it has a module called R-commander, which let things easier to deal and comes with several options as opening SPSS files (another statistical package commonly used by Windows users) and other things. THe problem is, as Rcmdr is a module for R, when I run it, it opens a terminal window and then he runs the module, which opens a friendly gui.
It worked okay and clean in Ubuntu 9.10, but for LTS 10.4 I keep getting an error, no matter I reinstall the modules or the entire program. I even installed Ubuntu again without upgrading it from karmic Koala. But there is the same error msg.
The error message says: "Error while creating a child process for this terminal". The strange part is there is no other msgs in the terminal or errorlogs. I really need to use this software for work.
