No GUI on Leap Server. No DISPLAY environment

Hi there, I installed Leap Server, tried to install a GUI to do some webpage design work but am running into some problems. I try to launch a browser, falkon and firefox and get these error messages:

  1. When typing firefox in the command line, I get this error
  • no DISPLAY environment variable specified
  1. When attempting to launch Falkon

qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin “xcb” in “” even though it was found.
qt.qpa.plugin: Could not find the Qt platform plugin “wayland” in “”
Fatal: This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may…
Available platform plugins are: eglfs, limuxfb, minimal, minimalegl, offscreen, vnc, xcb

Aborted (core Dumped)

So I am assuming there is something installation with Wayland or Xorg not properly setup, some packages missing, therefor not possible to set display environment.

    ” to install a Desktop Environment, everything that’s needed will be pulled in …
