Getting Gnome desktop.

A bit of a newbie question I'm afraid.I've just done a fresh install of the latest version and hoped to get the Gnome desktop, but have managed to end up with xcfe.I have searched for and tried all sorts of ways, each attempt has failed. Example screenshot attached.Maybe I have to install again?Some help would be much appreciated.

This should install the minimal GNOME stuff
sudo apt install --no-installl-recomends gnome-core

Thanks for that, do I type exactly as is, two dashes, 3 ls and one m, or are those just typos?

Those are probably wrong, just pasted from the net as i do not use gnome.
Should be 2 l and 2 m, either way it will complain if it is wrong.

sudo apt tasksel
sudo tasksel

Select the desktop you want
The reason why we use xfce is because it is an Xorg distro and gnome by default ues Wayland which linuxcnc may not like
On the log on screen bottom right, there is a cog icon that lets you select running gnome on xorg
