Comment 3 for bug 2063261

This turns out to be an issue with the bundle (revision: 440 line):

 kubernetes-control-plane:
    charm: kubernetes-control-plane
    channel: 1.29/stable
    revision: 440 # this is the amd64 version which will pull the amd64 cni resource
    num_units: 2
    to:
    - "5"
    - "6"
    options:
      channel: 1.29/stable

Most charms are arch independent, however in this occasion "revision: 440" pulls x86_64 artifacts.
