I followed Debian's Multiarch HOWTO to be able to install libcholmod3:armhf. I ran dpkg --add-architecture armhf but now if I run sudo apt-get update I get an error:

$ sudo apt-get update
[...]
Reading package lists... Done
E: Failed to fetch http://europe-west1.gce.archive.ubuntu.com/ubuntu/dists/zesty/main/binary-armhf/Packages  404  Not Found [IP: 192.158.31.252 80]

I see http://europe-west1.gce.archive.ubuntu.com/ubuntu/dists/zesty/main/ is missing the binary-armhf directory. What's the proper way of installing armhf packages on the Google Compute Engine platform?

There are two apparent issues:

1. The fetch failures when running apt-get update.

This is not actually a problem. As the message says, the errors are just ignored. The errors are gone by adding "[arch=amd64]" on each line in /etc/apt/sources.list, as described by https://wiki.debian.org/Multiarch/HOWTO#Setting_up_apt_sources

2. The fact that armhf seemed to be missing at the URLs in those fetch failure messages.

I did a grep europe-west1 /etc -R and /etc/apt/sources.list showed up. At the top of the file are a few options of making changes:

## if you wish to make changes you can:
## a.) add 'apt_preserve_sources_list: true' to /etc/cloud/cloud.cfg
##     or do the same in user-data
## b.) add sources in /etc/apt/sources.list.d
## c.) make changes to template file /etc/cloud/templates/sources.list.tmpl

To setup Multiarch for armhf on an amd64 Google Platform cloud machine is to add the following source using one of the options above:

deb [arch=armhf] http://ports.ubuntu.com/ubuntu-ports zesty main universe
