+## qt.qpa.plugin: Could not find the Qt platform plugin 'wayland' error
+^[Top](#top)
+
+If you run into this error message when running on modern Ubuntu which is using the wayland display 
+you most likely have not installed these following packages. 
+
+Solution:  Install or reinstall the required Qt Wayland packages.
+
+```
+Debian / Ubuntu based *nix
+    sudo apt install qt5-qtwayland             --< if QT 5
+    sudo apt install qt6-qtwayland             --< if QT 6
+
+Arch *nix
+    pacman -S qt5-wayland
+    pacman -S qt6-wayland
+```
+
+
+Alternatively you could set QT_QPA_PLATFORM environment to either wayland or xcb
+```
+export QT_QPA_PLATFORM=wayland
+
+export QT_QPA_PLATFORM=xcb
+```
