hi,
i have edited the sources.list file to include a new package i require, however when i run the apt-get update command i get a 404 not found error (..... .amazonaws.com/apt/dists/precise/contrib/binary-i386/Packages 404 not found). however inspecting the index online the packages are located in a binary-amd64 library.

I am running Ubuntu 12.04.1 64 bit on a vm ware virtual machine.

How would i be able to make Ubuntu direct to the binary-amd64 library and not binary-i386?

Thanks, Martin
