Packet Tracer Segmentation Fault Ubuntu 18.04

[noslin005]

I have installed Cisco Packet Tracer 7.1.1 on Ubuntu 18.04. Every time I launch the application it closes and give me a message `Segmentation fault (core dumped)`.
Using the `gdb`, I went to the installation directory `/opt/pt/bin` and I typed the following commands:

    $gdb Packettracer
    $gdb > run
    $gdb > where
Which reports a problem with `libpng` and `libcrypto.so.1.0.0`

    Warning: libpng warning: iCCP: known incorrect sRGB profile
    Warning: libpng warning: iCCP: known incorrect sRGB profile
 
    Thread 1 "PacketTracer7" received signal SIGSEGV, Segmentation fault.
    0x00007ffff79f49a7 in CRYPTO_add_lock () from /usr/lib/x86_64-linux- gnu/libcrypto.so.1.0.0

How can i fix this?

[dld2517]

I originally had this issue when I first installed PT. I did some research on the Internet and found a download for an older SSL library I think that I linked in to libcrypt.so.1.0.0 and it was called l

I ran a debug trace on this and here is what the output was: libssl1.0.0_1.0.1t-1+deb8u3_amd64.deb and the instructions said to install it using dpkg by typing

dpkg -i libssl1.0.0_1.0.1t-1+deb8u3_amd64.deb && apt get install -f

Well this worked originally. But today after updating some dependencies it stopped working. The library is still linked properly, as ldd gives the following output:

    libcrypto.so.1.0.0 => /usr/lib/x86_64-linux-gnu/libcrypto.so.1.0.0 (0x00007ff033e84000)

Starting from /opt/pt/binPacketTracer7 gives the report about problems with PNG images and then a segmentation fault.  Using GDB to further isolate the error I get the following

Thread 1 "PacketTracer7" received signal SIGSEGV, Segmentation fault.

i'm looking for a solution as well, unfortunately, it seems libcrypto.so.1.0.0.0 has been depracated and nowhere to be found ... seems it could possess the heartbleed vulnerability

so, if anyone has a solution, i'm interested as well

i'm installing PacketTracer7.2 on Debian Stretch 9.4

[dld2517]

I finally found the solution. I will send more later.

[c7b3rx]

what's the solution ?

[dld2517]

Well you have to download the old crypto library and link it to the new file names.

You also have to download icedtea7 package in order for it to work.

Iced tea is a package that uses java to integrate a java app with the browser. Honestly it is just a lot easier to forgot running it under Linux and just Windows. Cisco doesn’t care about supporting packet tracer under Linux or they would have fixed this error two years ago.

What did you do to resolve the issue?
I'm having the same problem using Debian10. We are using Debian 10 because it has Intel drivers needed for our labs NICs.

error:
$ /opt/pt/bin/PacketTracer7
Segmentation fault
cwc@42:~$
I've installed the follow:
apt install qtmultimedia5-dev libqt5webkit5-dev libqt5script5 libqt5scripttools5;
along with "libssl1.0.0_1.0.2l-1_bpo8+1_amd64.deb";

Thanks

You have to relink the qt5 files in the system libraries to the and also the libcrypt package needs to be relinked as well. There is another mode that the packet tracer application runs in. So you edit the actual script that executes the file.

I did all this in May and I have forgotten and didn’t take good notes. I ended up stepping through the debugger when the application was run and watched what library files were being called. Then I symlinked the libs to the ones I wanted.

[ICEBOWL]

Thank you.  could you provide your ldd and ls -l (ll) Please

When you relink the libraries  are they at /opt/pt/lib

This is my ldd on my Gentoo machine.  Which works with missing libraries.

could u explain it more clearly and write the code too
