Run “dpkg -i libpng12-0_1.2.50-2 + deb8u3_amd64.deb” to start the “libpng” installation on Ubuntu.

While installing Libpng, you may get an error in the terminal like below because the “multiarch-support” package is required for this software to work.

Run the “apt install multiarch-support” command to install the “multiarch” package in Ubuntu.

apt install multiarch-support

 

After trying to install “libpng” again, you will see that the process was successful. Try to run the simulator program with the “packettracer” command in the terminal.

Now Packet Tracer runs smoothly in Ubuntu.
