With openSUSE Tumbleweed I was not able to pass the login with my NetAcad-account, required to use PacketTracer. The login window opened, but no content, only a white blank window.
It turned out that the reason is Qt WebEngine sandboxing by default in openSUSE Tumbleweed. I do not know which other Linux distributions are also affected.
Solution: Insert the following into both startup scripts (/usr/local/bin/packettracer and /opt/pt/packettracer) to turn off sandboxing for PacketTracer.
QTWEBENGINE_DISABLE_SANDBOX=1For automatic installation my friend Tobi wrote a script that does all installation steps described in my blog post automatically. These two changes have just been committed to his script. Have a look to https://codeberg.org/toheine/pt-installer and download the script.
New script has been tested with PacketTracer 8.1.0 and 8.1.1 on openSUSE Tumbleweed
