I'm having trouble downloading xfce4 metapackage. I don't have a desktop yet just cmd line and this is my first time on linux.

sudo apt-get install xfce4

brings back Unable to locate package xfce4

Does that with all packages, leads me to sudo apt-get update Leaves me with temporary failure resolving 'downloads-distro.mongodb.org'

Read some solutions to fix this but it had me going in circles with no avail. Need to get this working from cmd prompt.

So I'm having trouble updating and am lost here without a desktop client. If anyone can help that would be great.
