Ubuntu – Packet tracer 7.1 won’t lauch Ubuntu 16.04 LTS

ciscosoftware installation

I am trying to run PacketTracer 7.1 on Ubuntu 16.04 LTS, everything installs fine, everything is accepted, however when I run the packettracer command, nothing happens… the shell just stays there.

I've already tried several solutions (adding lines and paths to the launch scripts, chmod on bash files, reinstalling, modifying paths), but nothing is happening, I did a clean installation on 2 different machines.

I finally was able to get some error messages out of it by running strace -f -o ~/Documents cpt_trace ran grep and got the following output.

$cat cpt_trace | grep error

3064  writev(2, [{"./PacketTracer7", 15}, {": ", 2}, {"error while loading shared libra"..., 36}, {": ", 2}, {"libicui18n.so.52", 16}, {": ", 2}, {"cannot open shared object file", 30}, {": ", 2}, {"No such file or directory", 25}, {"\n", 1}], 10) = 131

Resolved.
I modified the tpl.linguist and tpl.packettracer.

On the line with PTDIR=III, I changed it to PTDIR=/opt/pt.

Still did not work. Had to run it from /opt/pt/bin ./PacketTracer7, and it works now.

Ubuntu – Chromium is not working in Ubuntu 12.04

There are several steps to get the very latest chromium-browser package running on Precise Pangolin, but I have succeeded and so should you!

1. Install from PPA:

This PPA is not recommended for general use but worked well on my Precise Pangolin system:

sudo add-apt-repository ppa:canonical-chromium-builds/stage
sudo apt-get update
sudo apt-get install chromium-browser

chromium-browser will not work out of the box as you have experienced until a few other issues are attended to...

2. Missing libatomic:

You will see an error when loading chromium-browser from the command line: a missing library libatomic.so.1. You can search for this missing file by using the great utility apt-file:

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

(This creates a local index rather than a system one, use sudo apt-file update if you want a system index.)

You will be prompted to download file indices and you should accept this prompt and allow the download. Then search for the missing file:

andrew@ithaca:~$ apt-file search libatomic.so.1
gcc-mozilla: /usr/lib/gcc-mozilla/lib/libatomic.so.1
gcc-mozilla: /usr/lib/gcc-mozilla/lib/libatomic.so.1.0.0
gcc-mozilla: /usr/lib/gcc-mozilla/lib32/libatomic.so.1
gcc-mozilla: /usr/lib/gcc-mozilla/lib32/libatomic.so.1.0.0
andrew@ithaca:~$

You can see that it is part of the gcc-mozilla package which you can install as follows:

sudo apt-get install gcc-mozilla

Note that shared libraries are not sourced from the gcc-mozilla installation location as demonstrated here:

andrew@ithaca:~$ ldconfig -v 2>/dev/null | grep -v ^$'\t'
/usr/local/lib:
/lib/x86_64-linux-gnu:
/usr/lib/x86_64-linux-gnu:
/usr/lib/x86_64-linux-gnu/mesa-egl:
/usr/lib/x86_64-linux-gnu/mesa:
/lib32:
/usr/lib32:
/lib:
/usr/lib:
andrew@ithaca:~$

So we add an extra path for chromium-browser with a slight variation of the technique demonstrated by @Renaud:

sudo touch /etc/ld.so.conf.d/chromium-browser.conf
echo "/usr/lib/gcc-mozilla/lib" | sudo tee -a /etc/ld.so.conf.d/chromium-browser.conf
sudo ldconfig

And you will now see the added search path:

andrew@ithaca:~$ ldconfig -v 2>/dev/null | grep -v ^$'\t'
/usr/lib/gcc-mozilla/lib:   <------------- Here!
/usr/local/lib:
/lib/x86_64-linux-gnu:
/usr/lib/x86_64-linux-gnu:
/usr/lib/x86_64-linux-gnu/mesa-egl:
/usr/lib/x86_64-linux-gnu/mesa:
/lib32:
/usr/lib32:
/lib:
/usr/lib:
andrew@ithaca:~$

Note: If you try the aptitude build-dep chromium-browser method this step (adding the LD path) will still need to be followed...

But still more errors:

3. Missing libXss.so.1:

You will then get an error message:

error while loading shared libraries: libXss.so.1:
cannot open shared object file: No such file or directory

Once again apt-file will locate the appropriate package:

andrew@ithaca:~$ apt-file search libXss.so.1
libxss1: /usr/lib/x86_64-linux-gnu/libXss.so.1
libxss1: /usr/lib/x86_64-linux-gnu/libXss.so.1.0.0
libxss1-dbg: /usr/lib/debug/usr/lib/x86_64-linux-gnu/libXss.so.1.0.0
andrew@ithaca:~$

And then install this library as follows:

sudo apt-get install libxss1

And that should do it as chromium-browser has no problem finding the library once installed!

4. Running the browser:

Running nicely here:

andrew@ithaca:~$ chromium-browser --version
Chromium 52.0.2743.116 Built on Ubuntu , running on Ubuntu 12.04
andrew@ithaca:~$

And the obligatory screenshot:

Click for full sized image....

And have fun :)

Ubuntu – Cisco Packet Tracer 7.1 won’t start

I was able to run Cisco Packet Tracer 7.1 on Ubuntu 16.04 by doing the following:

1-Cisco Packet Tracer 7.1 requires an older version of a package not present on Ubuntu 16.04 so you need to get it by typing

wget http://security.ubuntu.com/ubuntu/pool/main/i/icu/libicu52_52.1-3ubuntu0.7_amd64.deb

2- To install the package you just downloaded type

sudo dpkg -i libicu52_52.1-3ubuntu0.7_amd64.deb

3- Verify proper installation using this commands

sudo updatedb; locate libicui18n

Check for the following packages to be installed:

/usr/lib/x86_64-linux-gnu/libicui18n.so.52
/usr/lib/x86_64-linux-gnu/libicui18n.so.52.1

Those are the packages needed by Cisco Packet Tracer to work properly.

Now you can type packettracer on terminal and the program should start.
