apt-move question

[Linda Hanigan]

I am trying to get apt-move working so I can use the security updates
without downloading them multiple times. I did fine tell I got to this
step. I changed the binary from i386 to amd64 to match my computer is
there something else in the line I need to change as well?

root at star:/home/general# cd /mirrors/debian
root at star:/mirrors/debian# apt-ftparchive packages pool/main/ \ | gzip
-9c > dists/dapper/main/binary-amd64/Packages.gz
E: Unable to open   - fopen (2 No such file or directory)
root at star:/mirrors/debian#

Also further into the howto it says you need a GPGKey set and ready to
sign.  What program would I need to do that?
                        Thanks
                         Linda
