So i just Installed Cisco Packet Tracer 7.2.1. on my Ubuntu 19.04, so I wanted to run it but it just tells:
aruberuto@aru-ubuntu:~$ packettracer
Starting Packet Tracer 7.2.1
But doesn't happen anything, I figured something was wrong so i opened /opt/pt/bin and tried to open from there with ./PacketTracer7:
aruberuto@aru-ubuntu:~$ cd /opt/pt/bin
aruberuto@aru-ubuntu:/opt/pt/bin$ ./PacketTracer7
./PacketTracer7: error while loading shared libraries: libpng12.so.0: cannot open shared object file: No such file or directory
And tells me that the library libpng.so.0 doesn't exist. And i tried to install a lot of packages for trying to solve it but it tells me that libpng.so.0 cant be updated because it doesn't exist.
I need help ;(
