Istiocd timeout when pursuing local deployment of kitt4sme.live cluster

Describe the bug

Bootstrap cluster procedure. We have provisioned a Virtual Machine with Multipass with the Ubuntu 20.04.1 LTS, GNU/Linux 5.4.0-42-generic x86_64, 8 CPUs, 16GB RAM/4GB swap, 120GB storage. When trying to install the Mesh infra Istio (istioctl install -y --verify -f profile.yaml), we get the error under additional content.

Additional context

We are pursuing a local deployment of the kitt4sme.live instance in our own box. We have followed the instructions of the Bootstrap cluster procedure. We have provisioned a Virtual Machine with Multipass with the Ubuntu 20.04.1 LTS, GNU/Linux 5.4.0-42-generic x86_64, 8 CPUs, 16GB RAM/4GB swap, 120GB storage. When trying to install the Mesh infra Istio (istioctl install -y --verify -f profile.yaml), we get the following error:

✔ Istio core installed

Do you have any hint on how we could resolve this issue? We have tried installing different compatible versions of Istio (1.11.4,1.12, 1.13.3 and 1.17)., and none of them worked. We have also increased RAM to 32GB and cpus to 10, but it did not work either. We have followed all the proposed solutions here, with no results.
