I would like to use the Ubuntu 18.04 screen sharing feature (Settings – Sharing), but all Windows clients I tried (RealVNC Viewer, TightVNC Viewer, TigerVNC Viewer) have more or less an identical error message: The server works, but the viewer doesn't support any of the server-mandated security types.
I have verified that it works when disabling encryption (gsettings set org.gnome.Vino require-encryption false
) but that's not an option for me, I want to connect my Windows 10 Pro to Ubuntu 18.04 with the encryption of course.
How do I achieve that?

I don't believe that after four years this bug will be solved any time soon. The solution might be to use another VNC server than the default one.
See this Ubuntu Community Help Wiki for a list of such servers : VNC/Servers.
Another alternative is the cross-platform NoMachine :
Another solution might be to install on Linux a server for the Remote Desktop protocol of Windows. xrdp might be a solution here :
