Why won't Nautilus open?

Question

linux

Installed nautilus file manager for the first time. When I run it, it gives an error:

** (org.gnome.Nautilus:5138): WARNING **: 13:30:23.313: Error on getting connection: Failed to load SPARQL backend: Cannot autolaunch D-Bus without X11 $DISPLAY
Unable to init server: Could not connect: Connection refused

(org.gnome.Nautilus:5138): Gtk-WARNING **: 13:30:23.330: cannot open display:

Although I installed x11 and D-Bus and even tried running nautilus with sudo but it didn't work.
Can you please tell me what to do.

Answer 1

Try
apt-get -y install x11vnc
Then reboot your OS

Answer 2

Nautilus (now called GNOME Files) for working environments (DE):
- Gnome
- Gnome Shell
- Unity (Gnome)
Accordingly, one of them must be installed ...
Usually, when installing these, Xs and a graphical display manager are automatically pulled up or prompted to install them.
GDM for Gnome and Gnome Shell
LightDM for Unity (Gnome)
What OS is installed?
