How to Install Cisco Packet Tracer 7.2.2 in Ubuntu 19.10 (Eoan Ermine) OS

Ubuntu is a community-developed system for laptops, desktops, and servers. Whether at home, at school, or at work, Ubuntu includes everything you might need, from word processors and email applications to web server software and programming tools.

Ubuntu will always be free. You do not pay for a usage license. You can download, use, and share Ubuntu with your friends, family, school, or business for free.

Every six months, a new version of the desktop and server version is released. This means you will always have the latest applications that the open-source world can offer you.

Ubuntu was designed with security in mind. In desktop and server versions, you will receive security updates freely for at least 18 months. With the Long Term Support (LTS) version, you have three years of support on the desktop version and five years on the server version. There is no extra payment for the LTS version, we do our best for everyone on the same free terms. Updates to the new version of Ubuntu are free and will always be free.

PT (Packet Tracer) is an interactive network simulation and learning tool. This tool allows you to create network typologies, simulate a network with multiple visual presentations, basically a didactic support tool.

It provides students with networking and troubleshooting experiences with virtually unlimited number of devices without having to buy real routers or switches.

After talking a bit about Ubuntu and Packet Tracer, let’s get to the point.

How to Use Packet Tracer on an Ubuntu PC

The latest version of Ubuntu is 19.10 (Eoan Ermine). The PT version is also 7.2.2

Before installing on your Linux computer, download the PT to your computer and then follow the steps below for step-by-step installation.

Step 1: Right-click on your Ubuntu desktop and open the terminal.

Step 2: Use the following command to change the permissions for the .run file you downloaded to your computer:

chmod +x PacketTracer-7.2.2-ubuntu-setup.run

Step 3: Use the following command to start the GUI wizard of Packet Tracer:

./PacketTracer-7.2.2-ubuntu-setup.run

Step 4: Accept the license agreement of the Cisco simulator and click Next to complete the installation. Then, the PT will try to open, but it won’t work because you need to install several dependent packages.

Step 5: To run Packet Tracer, you must first install the Libpng package. Use the following commands to install libpng:

wget http://ftp.us.debian.org/debian/pool/main/libp/libpng/libpng12-0_1.2.50-2+deb8u3_amd64.deb
sudo dpkg -i libpng12-0_1.2.50-2+deb8u3_amd64.deb

Step 6: When installing Libpng, you will also need to install this package if you receive a multiarch not installed error. Therefore, to install multiarch, use the following commands:

wget http://archive.ubuntu.com/ubuntu/pool/main/g/glibc/multiarch-support_2.29-0ubuntu2_amd64.deb
sudo dpkg -i multiarch-support_2.29-0ubuntu2_amd64.deb

Step 7: After installing the Multiarch package, try to install libpng again.

Step 8: After installing libpng, open the program by running the packettracer command on the terminal.

Step 9: Damn! Packet Tracer does not work again!

Step 10: The reason why Packet Tracer doesn’t work is libpng12.so.0. You need to extract the libpng.deb file to the folder and copy the libpng12.so.0 file to /opt/pt/bin/. To do this, use the following commands:

mkdir cpt; dpkg -x libpng12-0_1.2.50-2+deb8u3_amd64.deb ./cpt
cp ./cpt/lib/x86_64-linux-gnu/libpng12.so.0 /opt/pt/bin/

Step 11: After fixing Ubuntu libpng12.so.0 error, you can now use Packet Tracer on your computer without a problem!
