My first choice to run the installer was openSUSE:Leap:15.2 but I get:
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: xcb.
On Leap, Tumbleweed and in a virtual windows 7 installation it just fails.
It seems the above linux problem is caused by executing:
"sudo ./Emteria.OS_Installer-v1.1-14.AppImage" if I su to a root console then it succeeds.
