[SOLVED] QT5 Application: could not find or load the Qt platform plugin "xcb"

2

Hello

I’ve found a way to solve the problem.
I must add the kde-neon extension to the yaml file:

apps:
  dailydesktopwallpaperplus:
    command: DailyDesktopWallpaperPlus
    environment:
       DISABLE_WAYLAND: 1
    plugs:
        - home
        - network
        - opengl
        - x11
        - desktop
        - network-manager
        - desktop-legacy
   extensions:
        - kde-neon

The kde-neon extension involves QT5 Applications according this tutorial: Snapcraft Extensions

the way with the desktop-launch script is not actual anymore.

Regards
