Hello,
I installed Packet Tracer on Xubuntu 16.04 amd64. It didn't start at first, but it started after I installed the qtmultimedia5-dev package.
At start I get an error message:
"Cannot load ExApp. The executable file name or location may be incorrect, or the ExApp is not designed to be launched from Packet Tracer."
When it runs, all icons are black (mono) at top.
