Packet tracer

find /opt/packettracer -name qt.conf
/opt/packettracer/bin/qt.conf

Uh, so it was there… LOL I deleted the comment thinking I was on a false track.
OK post the contents of qt.conf.

confusedyeti03 · 4 December 2023 18:22

cat qt.conf

File: qt.conf
[Paths]
Prefix = ./
Libraries = ./
[Platforms]
WindowsArguments = altgr

meanruse · 4 December 2023 18:40

A shot in the dark: edit qt.conf and add Data = /usr/share/qt/ below [Paths].
If it does not work delete the line (revert the file as it was before, that is).

It doesn’t work says the same thing

Starting Packet Tracer 8.2.1
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.

Back to square one it seems.
You are still in the same shell where you set the variable before, right?
echo $QT_QPA_PLATFORM_PLUGIN_PATH prints something?

confusedyeti03 · 4 December 2023 18:48

It dosn’t show anything

meanruse · 4 December 2023 18:49

Ah.
set QT_QPA_PLATFORM_PLUGIN_PATH /usr/lib/qt/plugins/platforms
again then run it.
We’ll make that permanent later.

confusedyeti03 · 4 December 2023 18:49

It’s the same result doesn’t say anything

meanruse · 4 December 2023 18:51

I don’t understand, what does not say anything?

set QT_QPA_PLATFORM_PLUGIN_PATH /usr/lib/qt/plugins/platforms
then
packettracer

should either print errors or finally work

Anyways, the line I told you to add is likely wrong.
Try with Resources = /usr/share/qt/resources/ instead.

I’ll be back later (dinner).

Thank for the help until now, tomorrow morning I’ll continue searching and answer, but i don’t I’ll be able to try anything until 15:00.

I’ve also tried this:

fedora_33_Packet_tracer_8

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

Sounds like editing qt.conf did not do any good, at least before the “Qt platform plugin” error was gone. I’m out of ideas at this point. See you tomorrow then.

Sounds like a Wayland issue:

github.com/NixOS/nixpkgs

Packet Tracer 8 does not launch on sway (nixos-22.05)

opened 11:42AM - 08 Sep 22 UTC

0.kind: bug

### Describe the bug When I launch packettracer8, packaged in nixos, this is wh…at I get: ``` [nix-shell:~]$ packettracer8 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. [nix-shell:~]$ ``` ### Steps To Reproduce Steps to reproduce the behavior: 1. Use sway 2. Launch packet tracer ### Expected behavior Packet tracer launching. ### Notify maintainers  @lucasew ### Metadata Please run `nix-shell -p nix-info --run "nix-info -m"` and paste the result. ```console $ nix-shell -p nix-info --run "nix-info -m" - system: `"x86_64-linux"` - host os: `Linux 5.15.64, NixOS, 22.05 (Quokka), 22.05.2889.67e45078141` - multi-user?: `yes` - sandbox: `yes` - version: `nix-env (Nix) 2.9.1` - channels(root): `"nixos-22.05"` - channels(remy): `""` - nixpkgs: `/nix/var/nix/profiles/per-user/root/channels/nixos` ```

If you must have this app installed and working for school, you may need to install a desktop supporting X11.

Just a cursory search on my part so it’s hard to say.

Edit:

Sorry upon first glace, I thought the report was from Sept this year. I now see it was reported in 2022, so it’s not exactly a current report.

OK I found a supposed fix. It is for Fedora, but it sounds like it addresses exactly the same issue. I do not have packet tracer installed so I do not know if the solution works with Arch, (or if it requires some modification to work).

For anyone new to Linux (like me) wondering how and where to add the --no-sandbox args, these were the steps I took, I’m fairly new to Linux so I was scratching my head trying to figure it out, so bear with me:

Run these on a Terminal:

sudo nano /usr/share/applications/cisco-pt.desktop
search for the line that says Exec=/opt/pt/packettracer and add --no-sandbox args to the end of it. The whole line should say Exec=/opt/pt/packettracer --no-sandbox args.
press ctrl+o and enter to save
press ctrl+x to exit
I repeated the same steps mentioned above for the file /usr/share/applications/cisco-ptsa.desktop just to be sure.

At this point the files are ready, but you still need to re-run the xdg-menu scripts

Run these on a Terminal:

sudo xdg-desktop-menu install /usr/share/applications/cisco-pt.desktop
sudo xdg-desktop-menu install /usr/share/applications/cisco-ptsa.desktop
sudo update-mime-database /usr/share/mime
sudo gtk-update-icon-cache --force --ignore-theme-index /usr/share/icons/gnome
sudo xdg-mime default cisco-ptsa.desktop x-scheme-handler/pttp
sudo ln -sf /opt/pt/PacketTracer /usr/local/bin/PacketTracer

I just re-ran all of them because I’m not exactly sure which ones are needed lol, I logged out and Packet Tracer is working normally and I was able to log in with my Cisco credentials.

You downloaded the packettracer.tar.gz snapshot from AUR (en) - packettracer, extracted the PKGBUILD, then ran makepkg -si in a terminal in that directory, right? That’s all that should have been needed, no additional steps unless the build process called for it, right?

Is that the exact process you followed?

BluishHumility · 5 December 2023 03:11

Launch the program using one of the environment variables it has identified as valid.

QT_QPA_PLATFORM=xcb packettracer

Bonus content:

If you want to make a .desktop file for it (so you can start the program with your launcher), you can set it up as described here: https://wiki.archlinux.org/title/Desktop_entries#Modify_environment_variables

Copy the desktop file right out of the directory where you cloned the repo, and put it in ~/.local/share/applications:

cp cisco-pt.desktop ~/.local/share/applications/

Edit the file.

micro ~/.local/share/applications/cisco-pt.desktop

Add env QT_QPA_PLATFORM=xcb after Exec=, before the call to the binary. It should look like this when you are done:

[Desktop Entry]
Type=Application
Exec=env QT_QPA_PLATFORM=xcb /opt/packettracer/packettracer %f
Name=Packet Tracer 8.2.1
Icon=/opt/packettracer/art/app.png
Terminal=false
StartupNotify=true
MimeType=application/x-pt;application/x-pka;application/x-pkz;application/x-pks;application/x-pksz;
Categories=Network;

Save and exit the file, then you should be able to start the application from your launcher if you want to.
