debootstrap etch unknown key

[Mike Fitzgerald]

Hi

I've got a Cobalt Raq4 and am trying install etch (that's the most 
recent version it will take) but when issuing:

root@debian:/# debootstrap --arch i386 etch /nfsroot-x86 
http://archive.debian.org/debian/

I get the following error messages:

I: Retrieving Release
I: Retrieving Release.gpg
I: Checking Release signature
E: Release signed by unknown key (key id B5D0C804ADB11277)

Any ideas what is wrong? This is my first foray into this territory

Thanks

Mike Fitzgerald
