Can't install 1.7.2 on ARM64

Hi,
I’ve been trying today to install Istio on a 5-node Raspi-4 cluster running Ubuntu server (ARM64). There is a binary specifically for that arch, yet I’ve tried on both K3S and Microk8s and neither one will install. This is the output of the microk8s installation:

~/istio-1.7.2# istioctl install --set profile=demo
Detected that your cluster does not support third party JWT authentication. Falling back to less secure first party JWT. See https://istio.io/docs/ops/best-practices/security/#configure-third-party-service-account-tokens for details.

Am I missing something obvious here?

Thanks,
