qt.qpa.xcb: could not connect to display

edit

I am trying to run turtlesim_node as shown below:

unix20p04p4@DESKTOP-RKF1B6O:~$ ros2 run turtlesim turtlesim_node

Unfortunately, I am getting the following result:

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.                                                                                This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.                                                                                                                                                                                                             Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

Please help.
