Problem: I'm enrolled in a class that needs to use Packet Tracer for my school work.  Cisco provides a Linux package, but its a Debian package (deb).
Tried to use alien to convert from .deb to .rpm, but found this solution for Packet Tracer 7.3.  Adapted for Packet Tracer 8 on Fedora 33.

Starting point: 

https://ask.fedoraproject.org/t/how-to-install-new-cisco-packet-tracer-7-3-on-fedora-31-workstation/6047/8

Alien aborts due to conflicts (probably can be overcome)

Environment: Fedora 33 // Packet Tracer 8.0

rm -rf /opt/pt
rm -rf /usr/share/applications/cisco*.desktop
rm -rf /usr/share/applications/cisco*.desktop
rm -rf /usr/share/icons/hicolor/48x48/apps/pt7.png // may need to update for PT8

mkdir ~/pt80
cp ~/Downloads/PacketTracer_800_amd64_build212_final.deb ~/pt80
cd ~/pt80

# Extract debian image using the 'ar' command
ar -xv PacketTracer_800_amd64_build212_final.deb
mkdir control
mkdir data
tar -C control -Jxf control.tar.xz
tar -C data -Jxf data.tar.xz
cd data
sudo cp -r usr /
sudo cp -r opt /

# gnome stuff -
