Just to help some ppl, I had some troubles and the error message when running the /usr/lib/packettracker/packettracer.AppImage was:
Fatal: This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: linuxfb, xcb.
NOTE: I'm currently in sway
I thought the fix was putting: QT_QPA_PLATFORM=xcb in the ~/.bashrc, instead, it was actually putting it inside ~/.profile.
QT_QPA_PLATFORM=xcb
without the "" double quotes

can anyone drag and drog modules on a device? I'm running through this issue and it seems there's no other option rather than downgrading the version.

After executing /usr/lib/packettracer/packettracer.AppImage, on the UELA login window select Advance settings and check the box for using internal browser. You should be able to login afterwards.

If text is tiny, try something like:
env QT_SCALE_FACTOR_ROUNDING_POLICY=Round QT_SCALE_FACTOR=1.333333 /usr/lib/packettracer/packettracer.AppImage "$HOME/Documents/CCNA/JITL/CCNA Mega Lab (Jeremy's IT Lab).pka"

Please add conflict with packettracer900-bin.

I'm also having the same issues with any preferences made not saving, and also having to log on for each session, which is something I did not have to do on 8.2.2.

After install version 9.0.0, you should execute from console: "./usr/lib/packettracer/packettracer.AppImage" in order to accept the license and install the desktop files.

To install all versions of packettracer except 7.2.2, follow this guidelines: 1. Download the snapshot from this AUR. 2. Tar -zxf the packettracer.tar.gz snapshot (it creates the dir packettracer/ with the PKGBUILD on it). 3. Download the latest packettracer tarball from your Netacad account and copy it into the packettracer/ dir. 4. Create the package with the command makepkg (it creates a packettracer.pkg.tar.xz). 5. Install the package with either makepkg -i or sudo pacman -U packettracer.pkg.tar.xz.
Packettracer 7.2.2 are auto installable via run file, download it from netacad webpage and run it, you don't need this package.
