I have download Packet Tracer 7.1.1 64-bit (which is for Ubuntu 14.04). I run the script installer and all works great.

The problem is that it doesn't start. After a check with ldd it seems that it misses I can't find this specific library in official repos.

I checked my system and it is installed by Anaconda Python 3, so i copied it. If i run packettracer from terminal nothing happens nor i get any log in journal. If i run it from /opt/pt/bin where is installed with ./PacketTracer7 i get seg fault. Running a check with ldd again it says that the library copied from Anaconda is the wrong version.

So i managed to to get the original library file from an Ubuntu 14.04. Checked with ldd again all looking fine, except when i try to run it from terminal again with packettracer nothing happens.

If i run it as ./PacketTracer7 it starts normally, but after a few seconds i get a seg fault again.

Any ideas ?


Finally i was able to solve the issue. In order to make it work for Fedora 27, you need totally four shared libraries, which you just copy to /lib64 and run a sudo ldconfing

The libraries are:,, and

They all need to be 64-bit x8664. The way i obtain them is by a live image of Ubuntu 14.04 64-bit x8664 on a USB.

Hello, I know it's a little late, but is this workaround effective for F28 as well? I added those libraries in /lib64 then sudo ldconfig, tried launching /opt/pt/bin/PacketTracer still getting errors AND no PT GUI:

*./PacketTracer7: /usr/lib64/ no version information available (required by ./PacketTracer7)
QFSFileEngine::open: No file name specified
Warning: QT_DEVICE_PIXEL_RATIO is deprecated. Instead use:
   QT_AUTO_SCREEN_SCALE_FACTOR to enable platform plugin controlled per-screen factors.
   QT_SCREEN_SCALE_FACTORS to set per-scr

Thank you! It worked for me, though I'm on Fedora 28 using PT 7.1.1 (not Fed29, PT7.2). Apparently, I needed to install libpng12. Launching /opt/pt/bin/PacketTracer still gave error msgs:

/opt/pt/bin/PacketTracer7: /usr/lib64/ no version information available (required by /opt/pt/bin/PacketTracer7)  [...]

Then I tried just typing packettracer on the Terminal and it worked, took some time, but it worked. Thank you!

Hi guys!

I've just made a Flatpak builder manifest for the Cisco Packet Tracer. It's the most simple and clean way to run this beast. See at

Tried it, didn't work. Here's what I get after giving the cmd flatpak-builder --user --install build-dir flatpak-pt/

error: org.freedesktop.Platform/x86_64/18.08 not installed
Failed to init: Unable to find runtime org.freedesktop.Platform version 18.08

Any idea what this error is about? (I had skipped the flatpak install flathub org.freedesktop.Sdk/x86_64/18.08 cmd but went back, installed flathub etc., then again tried building it and got this error). Should I move dir flatpak-pt from ~/Downloads to home?

Do I have to decompress the *.tar.gz file?

I gave better instructions in, please try again from the start. You can keep this stuff in your ~/Downloads folder.

Sorry for the late answer, I did not get email notification from the site about your comment. :/
