I am on Jammy Ubuntu, I create an AppImage with appimage-builder --recipe AppImageBuilder.yml

my AppImageBuilder.yml is :

```nohighlight
# appimage-builder recipe see https://appimage-builder.readthedocs.io for details
version: 1
script: |
  # remove any existent binaries
  rm -rf AppDir | true

  # compile and install binaries into AppDir

  make install DESTDIR=AppDir
AppDir:

```

In my system Jammy the appimage works correctly but in other linux (x11 or wayland) i have this error :

```nohighlight
qt.qpa.plugin: Could not find the Qt platform plugin "wayland" in ""
qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

```

It’s a bug or It’s from me ?

when i try to debug :  
`qDebug() << "PluginPath is : " << QLibraryInfo::location(QLibraryInfo::PluginsPath);`  
the result is :  
`PluginPath is : "/tmp/.mount_Francex0mlxO/usr/lib/x86_64-linux-gnu/qt6/plugins"`  
its the correct path

Hello @Paullux, thanks for asking. I think it would be best to ask over at [Issues · AppImageCrafters/appimage-builder · GitHub](https://github.com/AppImageCrafters/appimage-builder/issues) since I don’t know whether the appimage-builder developer is reading here.

Not sure anyone has ever tried this… very bleeding edge 😉
