Install on bare metal not succeeding (no standard input)

on https://docs.fedoraproject.org/en-US/fedora-coreos/bare-metal/ I tried installing from iso with example.fcc:

variant: fcos
version: 1.0.0
passwd:
users:
- name: core
password_hash: “my long secret hash”
groups:
- wheel
- sudo

podman run -i --rm quay.io/coreos/fcct:release --pretty --strict < example.fcc > example.ign
gives example.ign:

{
“ignition”: {
“config”: {
“replace”: {
“source”: null,
“verification”: {}
}
},
“security”: {
“tls”: {}
},
“timeouts”: {},
“version”: “3.0.0”
},
“passwd”: {
“users”: [
{
“groups”: [
“wheel”,
“sudo”
],
“name”: “core”,
“passwordHash”: “my long secret hash”
}
]
},
“storage”: {},
“systemd”: {}
}
I install according to instruction (live-boot+ sudo coreos-installer install /dev/sda --ignition example.ign and sudo reboot) I get errors related to standard input not set and everything freezes…

How to solve this?

What are the errors?

Note that Fedora CoreOS reports Ignition errors to the serial console by default. To see them on the VGA console, remove console=ttyS0,115200 from the kernel command line.

there is no kernel command line I can edit, there is no grub boot, this is a install following the docs and it’s not working. The errors are almost literraly: “STDIN standard input not set” and then everything freezes
