            @yohu12 this is the same as MagicMirror/installers/mm.sh

            Are u doing this over vpn?

            Also the operating system must have xwindows running…

              I saw this error because the raspi was set to Autologin as “pi” and I had created another user which could not take control of the display.

                I saw this just yesterday (followed by a few other warnings). Solution was to follow pretty much this ancient but still working how-to for jessie:
                jessie-lite-installation-guide
                (especially points describing “Install Xserver, LXDE-gui and lightdm” and missing packages)

                Raspberry Pi 4
                Raspbian Buster
                MagicMirror² v2.8.0
