that contains (btw. I've tried with the version being a Number w/o quotes and

"network":
"ethernets":
"eth0":
"gateway4": "192.168.1.1"

"set-name": "eth0"
"version": "2"

After running on Raspberry Pi 4B with 4 GB, created with
ubuntu-20.04.1-preinstalled-server-arm64+raspi.img.xz, the machine's setup
fails and /var/log/cloud-init.log reveals that:
