Somehow pip needs to (re)build something so needed to install gcc and python3-dev.
After:
apt-get install gcc python3-dev
curl https://raw.githubusercontent.com/NethServer/ns8-core/main/core/install.sh > install.sh
bash install.sh ghcr.io/tbaile/core:main
The node is up and running on arm64 (aarch64)
