Can't run Cisco PT on Debian GNU/Linux

Hi there,

I'm studying IT and we're using for the first time PT for networks simulation.

As I'm actually novice (by the way, I'm not even sure I'm posting in the right branch, sorry but I've just signed up and I absolutely don't know how this community works), I'm having troubles running PT on Debian.

I installed PT yesterday by running ./ packettraceretc. and the installation started, everything seemed to go well and the installation finished.

But, when I try running PT by clicking on the icon (neither running it by terminal seems to work), the terminal returns "Packet tracer is starting" and nothing happens.

Besides, the fact that no errors pop up it's really annoyng, and moreover PT still works on Ubuntu...Does anyone knows how come?
