in hack/lib/common.sh, it need to get six runtime deployment files and maybe fail with connection refused.

# local function to download runtime deployment file
copyRuntimeDeploymentFile() {
  if [[ $# != 2 ]]; then
    echo "Invalid args in copyRuntimeDeploymentFile"
    exit 1
  fi

  fileName=$1
  pathInSrc=$2
  if [[ (${OVERWRITE_DEPLOYMENT_FILES} == "true") || (! -f ${VIRTLET_DEPLOYMENT_FILES_DIR}/${fileName}) ]]; then 
    echo "Getting runtime deployment file " ${fileName}
    wget -O ${VIRTLET_DEPLOYMENT_FILES_DIR}/${fileName}  ${VIRTLET_DEPLOYMENT_FILES_SRC}/${pathInSrc}
  fi
}
# Get runtime deployment files
copyRuntimeDeploymentFile "libvirt-qemu" "apparmor/libvirt-qemu"
copyRuntimeDeploymentFile "libvirtd" "apparmor/libvirtd"
copyRuntimeDeploymentFile "virtlet" "apparmor/virtlet"
copyRuntimeDeploymentFile "vms" "apparmor/vms"
copyRuntimeDeploymentFile "vmruntime.yaml" "data/virtlet-ds.yaml"
copyRuntimeDeploymentFile "images.yaml" "images.yaml"

It need to add a retry count in code

wget -O ${VIRTLET_DEPLOYMENT_FILES_DIR}/${fileName}  ${VIRTLET_DEPLOYMENT_FILES_SRC}/${pathInSrc}

Maybe it's like this

wget -t 10 -O ${VIRTLET_DEPLOYMENT_FILES_DIR}/${fileName}  ${VIRTLET_DEPLOYMENT_FILES_SRC}/${pathInSrc}

[ZongbaoLiu]

It can be solved, like this

wget --no-check-certificate -O ${VIRTLET_DEPLOYMENT_FILES_DIR}/${fileName}  ${VIRTLET_DEPLOYMENT_FILES_SRC}/${pathInSrc}
