Installing GDC / Linux / x86-64 when apt-get doesn’t work

[Cecil Ward via Digitalmars-d-learn]

I’m trying to install GDC on a new Linux box and I don’t know 
what I’m doing. Background: I have installed LDC successfully and 
have installed GDC on a Raspberry Pi using 32-bit ARM.

For some reason the apt-get command doesn’t work on this machine, 
don’t know why. The machine is a virtual server hosted on the 
internet and I can get support for the o/s.

What is the recommended procedure for fetching the x86-64 
prec-compiled GDC?
