/sbin/init: error while loading shared libraries: libdbus-1.so.3: cannot open shared object or file: No such file or directory

"i tried to install file libc.so.6 in shared library and in this process i had done some mistake and that i don't know what exactly it is"

Can you be more specific? What was it you were trying to do? Were you following instructions somewhere?

In addition to providing that information, please also open a Terminal window and run these commands, one after the other, in this order:

apt-cache policy libdbus-1-3 ia32-libs libc6 libc6-\*
locate libdbus-1.so.3 libc.so.6
sudo updatedb
locate libdbus-1.so.3 libc.so.6

To run a command, paste it into the Terminal (this is preferable to typing it in by hand as it's faster and easier and the risk of mistakes is much smaller) and press enter. It is intentional that the second and fourth command are identical. They might produce identical output, or they might not. You may be prompted for your password when you run the third command. As you enter it, you won't see any placeholder characters (like *). That's OK, just type it in and press enter. This third command might take only a short time to complete, or it might take a while--you should wait 5-10 minutes before worrying that it might not finish.

Then select all the text in the Terminal (Edit > Select All), copy it to the clipboard (Edit > Copy), and paste it here.

HI Eliah kagan,

I followed the same procedure as you mentioned above and produce the result below this message and you can see the error while trying to install MATLAB in my computer. I want to install MATLAB at any cost in my ubuntu system because i want to completely migrate from windows to this linux machine.

Anyway thanks for your quick reply and give me a solution to this problem as early as possible.

This post does not address the fundamental problem preventing MATLAB from installing. Instead, it focuses on the way you're installing it. You can ignore this post if you really want to, but I recommend you read it, as it might help you to avoid other problems later. I'll post again shortly to work on a solution to your problem.

The instructions at http://ubuntuforums.org/showthread.php?t=676523&highlight=installing+matlab&page=2 are for a much older version of MATLAB than the one you're attempting to install. You would be better off consulting the official documentation (written documentation, documentation on the CD or in the .iso image, or documentation on the MATLAB website).

I have also noticed that you are doing a couple of things that seem like they made lead to problems later. Your user account (without sudoing to root) seems to have write access to /usr/local. It's fine for trusted users to have write access to /usr/local/src, as not having to sudo to root to work inside /usr/local/src decreases the chance of bad mistakes. But having access to write inside /usr/local itself is probably a bad thing. And /usr/local is a bad place in which to do your work.

If you were thinking of installing MATLAB into somewhere with a name like /usr/local/matlab..., well, you could, and I'd go ahead and do that if that's what the installer wants to do, but the installer is more likely to want to install somewhere inside /opt, which is a more standard place to put a program installed from an automated binary-only installer (like MATLAB).

Also, if you're installing MATLAB 2010a, you should really not be creating or using a folder called MATLAB 2010b. That may lead to enormous confusion later if some day you *do* actually install MATLAB 2010b and forget even in the smallest detail about what you did this time around.

If they are empty, I recommend you remove the /usr/local/matlab2010a and /usr/local/matlab2010b directories. If there is documentation for installing MATLAB, I recommend you work for that. Otherwise, the best way to install it would probably be:

cd /media/iso
sudo ./install

(You can really run the installer from anywhere, though. But I don't recommend you start out with the destination directory for the MATLAB installation already created. The installer can create the directory where it wants it--generally speaking, it's a good idea to let it install where it likes.)

When MATLAB tried to install, for some reason it looked for libc.so.6 in /lib. That might just be a bug in the installer--it might not actually check where libc.so.6 is located. If that's the case, we can work around the problem easily. But the new error message "/sbin/init: error while loading shared libraries: libdbus-1.so.3: cannot open shared object or file: No such file or directory" during boot is cause for concern. It merits investigation.

If you need to get MATLAB installed and running right away, a simple workaround that will likely enable the installation to proceed is to create a symbolic link for libc.so.6 in /lib. You can do that by running this command:

sudo ln -s /lib/i386-linux-gnu/libc.so.6 /lib/libc.so.6

I highly recommend you copy and paste (rather than retyping) that command, so as to minimize the chance of typos.

After you create that, you can run the installer again and see what happens.

On the other hand, if you have the time to investigate this new boot-time error message, I'd recommend doing that first--it's possible that the MATLAB installer is causing it. It's also possible that it's entirely innocuous (or that the only breakage it indicates is in MATLAB itself). It's also possible that it indicates a greater problem.

To investigate that, press Alt+F2 and run:

gedit /var/log/syslog

Select all the text (Ctrl+A) and copy it to the clipboard (Ctrl+C).

If this file is less than 300 lines (you can to go to the very end and see the line number for the last line), please go ahead and paste it here. If it's more than 300 lines, please instead paste it at http://paste.ubuntu.com and post a link to it here. That file may contain a log of the events relating to the "/sbin/init: error while loading shared libraries: libdbus-1.so.3: cannot open shared object or file: No such file or directory" error message.

Hi Eliah kagan,
I forget to say that the original error "/sbin/init: error while loading shared libraries: libdbus-1.so.3: cannot open shared object or file: No such file or directory" has been solved by using ubuntu live cd. Now i don't get this error and system works fine.

Now my problem is with installation of MATLAB and i followed your suggestions in this post but still i was unable to rectify the problem in it. It was installing in first attempt and works fine, when i quit from this matlab and there was no installation candidate of matlab in ubuntu system.

Below is the error producing my terminal:
 bhaskar@bhaskar-Inspiron-1525:/media/iso$ sudo modprobe loop
 bhaskar@bhaskar-Inspiron-1525:/media/iso$ sudo mount -t iso9660 -o loop /home/bhaskar/Desktop/Matlab.UNIX.R2010a.iso /media/iso

I came with another problem of running vsftpd (FTP) server in ubnut system. Previously it was worked fine( that mean there are no problems in starting/stopping/restarting vsftpd). Now i installed again this vsftpd after recoverd ubuntu from live cd , i am getting the following error in terminal:
bhaskar@bhaskar-Inspiron-1525:~$ sudo service vsftpd start
[sudo] password for bhaskar:

Warning: Fake initctl called, doing nothing.
bhaskar@bhaskar-Inspiron-1525:~$

I have been posted my log file in http://paste.ubuntu.com and below is the log file link in paste ubuntu website.
http://paste.ubuntu.com/607332/

Can you suggest some good websites to learn better about ubuntu and it's networking.

"I forget to say that the original error .... has been solved by using ubuntu live cd."

Can you elaborate further about how you solved this problem? If the problem was triggered by MATLAB, then by understanding how you solved it, I might be better able to help you install MATLAB successfully.

In addition, know what you did when working from the live CD should help in figuring out what changed to keep vsftpd from working. Normally I would ask you to post a separate question about your problem with vsftpd, but it looks like it may be related to the MATLAB problem insofar as whatever you did to fix the libdbus-1.so.3 error may have caused the vsftpd problem.

I solved the problem by inserting the ubuntu live cd and then i got a option in installing as "upgrade from ubutu 11.04 to ubuntu 11.04" and proceeded from this option, in this process the file system has been recovered from the ubuntu live cd at the same time all of my third party applications are disappeared (removed) from my ubuntu system.
The reason for these third party applications are disappeared because i was removed the ubuntu live cd in the middle of recovering process. And why i am removed this live cd is because of the recovering process may not proceeding after some time.

It was already version 11.04 before you selected to upgrade (to the same version)?

Which third party applications? Are you talking about applications installed from PPA's, or are you talking about applications like MATLAB?

It's standard for applications installed from PPA's to sometimes be removed when upgrading to a new release of Ubuntu. This would not necessarily be a result of your having interrupted the upgrade process.

> And why i am removed this live cd is because of the recovering
> process may not proceeding after some time.

For how long was it stalled, and what was it doing when it was stalled (for example, what step of the upgrade did it say it was performing)?

1. My ubuntu has already version of ubuntu 11.04 for recovery purposes i was chosen this option.

2. Yes the applications installed from PPA's like vlc, google chrome, skype etc........

3. It was stalled for almost half-hour and at the stall it was recovering third party applications( it's approximately) but recovering file system was already over before this stall time.

Try installing MATLAB with:

sudo ./install -t

If that doesn't work, please post another reply.

It's my great pleasure to get help from you and i am totally welcomed to your way of supporting others.

Thanks.
Bhaskar

Note: This is a process to add matlab PATH variable to existing system PATH variable by following commands.
PATH=$PATH:/usr/local/matlab2010a/bin/
export PATH
Now the matlab path variable is coming to system variable PATH and now the shell will looks this matlab path variable.
This is recently found from my recent Matlab installation.

The problem now pending is to attach matlab icon to desktop.

The following link will tell how to remove a PATH variable from the existing system PATH variable by executing the following
http://www.linuxjournal.com/content/remove-path-your-path-variable-0

Remove a path from your PATH variable

  HOW-TOs
If you need to remove a path from the PATH variable before your script runs add this to the beginning of the script:
  PATH=$(echo $PATH | sed -e 's;:\?/home/user/bin;;' -e 's;/home/user/bin:\?;;')
If you need, you can re-add it at the front of the list with:
  PATH=/home/user/bin:$PATH
Or you can re-add it at the end of the list with:
 PATH=$PATH:/home/user/bin

launcher can be installed using the ubuntu help website. And launcher can be found in the dash by providing the complete path address in /usr/share/applications/matlab.desktop file. where (exec = matlab -arch=glnx86 -desktop) can be edited with below.
exec = /usr/local/MATLAB/R2012a/bin/matlab -arch=glnx86 -desktop and the path may vary based on your installation.
