Hello Astromate ...
I have installed from scratch Indi/Ekos with Ubuntu Mate onto a Raspberry PI 3 without problem but when I start Kstarts I get a bad keyboard layer
so I have formatted the SD card and have reinstalled all the soft but this is the same issue.
I have installed KDE language pack french, changed language into Kstars but nothing better.
So, all others applications under Ubuntu work well, exemple Open Office ....I use TightvncServer to be connected from Windows 10 with UltraVnc.
What's wrong ?
Many thanks in advance

Gérard

This is well known issue with TightVNC. The only solution I know is to change VNC server to something else e.g. x11vnc

Thanks Kaczorek,
I have just installed Vnc4server and it works better now ...
