WebEx on 64-bit Ubuntu 13.10

Periodically, I use WebEx with work. It seems like it is just often enough to remind me that I didn’t make sure it was working since my last install.

Well, thanks to Russ Lowenthal, I found an easy fix to get it working.

Ask Ubuntu: How to I make Cisco WebEx work with 13.10 64bit?

Existing directory

Well first, he has you look for missing libraries in the config directory. The problem is, I had two of them already.

$ ls $HOME/.webex 
1124  1424  lastshareindex.bak

I just deleted the directory to start from scratch.

rm -r .webex/

I started a new WebEx from my browser. I just logged into the meeting and ended it. After that, I had just one directory there:

$ ls $HOME/.webex 

As a side note, the Meeting Center opens at this point. I just can’t share my desktop or view someone else’s.

Finding Missing Libraries

Next, I ran this command to identify the missing libraries.

ldd $HOME/.webex/1424/*.so >>check.txt

I could have opened the check.txt with gedit or something like that. It was easier to use grep to find all of the “not found” lines:

$ grep "not found" check.txt 
	libgtk-x11-2.0.so.0 => not found
	libgdk-x11-2.0.so.0 => not found
	libXmu.so.6 => not found
	libXtst.so.6 => not found
	libjawt.so => not found
	libjawt.so => not found
	libXmu.so.6 => not found
	libpangoxft-1.0.so.0 => not found
	libXft.so.2 => not found
	libpangoft2-1.0.so.0 => not found
	libpangox-1.0.so.0 => not found

Then, I installed the apt-file program.

sudo apt-get install apt-file
apt-file update

Finally, I used it to search each of the libraries that were not found.

$ apt-file search libXmu.so.6
libxmu6: /usr/lib/x86_64-linux-gnu/libXmu.so.6
libxmu6: /usr/lib/x86_64-linux-gnu/libXmu.so.6.2.0
libxmu6-dbg: /usr/lib/debug/usr/lib/x86_64-linux-gnu/libXmu.so.6.2.0

Once I knew the libraries, I could use that to install them. Not each of these actually installed packages because some were dependencies.

sudo apt-get install -y libgtk2.0-0:i386
sudo apt-get install -y libxmu6:i386
sudo apt-get install -y libgcj14-awt:i386
sudo apt-get install -y libpangoxft-1.0-0:i386
sudo apt-get install -y libxft2:i386
sudo apt-get install -y libpangoft2-1.0-0:i386
sudo apt-get install -y libpangox-1.0-0:i386

I didn’t even have to reboot or even restart my browser. The next meeting worked fine and showed me the shared desktop.

  1. Came across the same issue today and these instructions worked well.

    I was on ubuntu 12.04.4 LTS version and the only change was that I was unable to install libgcj14-awt:i386 or the 12.04 equivalent libgcj12-awt:i386

    I was able to get around this by installing

    sudo apt-get install -y openjdk-7-jre-headless:i386

    and all worked perfectly.

    I also installed ia32-libs but I’m not sure if that was required.

    sudo apt-get install -y ia32-libs

  2. Forgive the ignorance, relative newbie here.

    I have one question – why do you put the :i386 in the command line? What does that do, and if you are 64 bit, would you not use whatever value for a 64-bit system?

    1. @chuck, No problem — forgive the late reply.

      The :i386 forces it to load the 32-bit package. The problem is that even though my system is 64-bit, the software is 32-bit and will only work with 32-bit libraries.

      So, basically, the :i386 tells it to load the 32-bit version even though I have a 64-bit OS.

      1. @digital – your instructions and this process is very informative, I’m learning alot from this, many thanks! I noticed that for the java stuff (libgcj14-awt) on my system, there were serveral packages that contained this:
        gcc-snapshot: /usr/lib/gcc-snapshot/lib/gcj-4.9.0-15/libjawt.so
        gcc-snapshot: /usr/lib/jvm/java-1.5.0-gcj-4.9-snap-amd64/jre/lib/amd64/libjawt.so
        gcj-4.8-jre: /usr/lib/jvm/java-1.5.0-gcj-4.8-amd64/jre/lib/amd64/libjawt.so
        libgcj14-awt: /usr/lib/jvm/java-1.5.0-gcj-4.8-amd64/lib/libjawt.so
        libgcj14-awt: /usr/lib/x86_64-linux-gnu/gcj-4.8-14/libjawt.so
        libgcj14-dbg: /usr/lib/debug/usr/lib/x86_64-linux-gnu/gcj-4.8-14/libjawt.so
        openjdk-6-dbg: /usr/lib/debug/usr/lib/jvm/java-6-openjdk-amd64/jre/lib/amd64/libjawt.so
        openjdk-6-jre-headless: /usr/lib/jvm/java-6-openjdk-amd64/jre/lib/amd64/libjawt.so
        openjdk-7-dbg: /usr/lib/debug/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/libjawt.so
        openjdk-7-jre-headless: /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/libjawt.so

        Does it matter which one I install for this? I think there are others too, but just wanted to know

        Thanks again!

  3. hi chuck
    I also have 64 bit ubuntu 14.04. and my problem while executing webex is I get this message.

    the audio device is unaccessable now.

    thus, no sound.

    to resolve this
    I followed the above steps.
    after installing some packages I also eneded with
    this line in check.txt (like chuck I guess):

    libjawt.so => not found

    after entering this:

    apt-file search libjawt.so

    I get the same list as chuck got above. observing that
    libgcj14-awt package has this file
    I tried to install the 32 version of libgcj14-awt using:

    sudo apt-get install -y libgcj14-awt:i386

    but I get the reply:

    libgcj14-awt:i386 is already the newest version

    but still after removing .webex directory and executing once more webex application I get this line again in check.txt:

    libjawt.so => not found

    so I thought maybe to install gcj-4.8-jre:i386 that also has libjawt.so using:

    sudo apt-get install -y gcj-4.8-jre:i386

    but I get this reply:

    gcj-4.8-jre:i386 : Depends: gcj-4.8-jre-headless:i386 (= 4.8.4-2ubuntu1~14.04.1) but it is not going to be installed
    E: Unable to correct problems, you have held broken packages.

    so what should I do next to execute webex
