Hi,

I’m having a problem booting a system up using PXE, any help is really appreciated.
The boot arguments where taken from the Installation guide

Environment

VMware Fusion 11.5.3
Guest: 2 CPU, 4 GB, efi boot
iPXE booting

The boot arguments are

set swboot-url http://10.13.1.5/os
set fedoracos-release 31.20200505.3.0
initrd  ${swboot-url}/pxe/unattend/lnx/fedoracos/fedora-coreos-${fedoracos-release}-live-initramfs.${arch_fedora}.img
boot    ${swboot-url}/pxe/unattend/lnx/fedoracos/fedora-coreos-${fedoracos-release}-live-kernel-${arch_fedora} \
    initrd=fedora-coreos-${fedoracos-release}-live-initramfs.${arch_fedora}.img \
    ignition.config.url=${swboot-url}/pxe/unattend/lnx/fedoracos/config.ign \
    ignition.firstboot ignition.platform.id=metal \
    ip=dhcp rd.neednet=1 console=tty0 console=ttyS0

Here is the error message I get.

Thanks for the report @beerworks - I was able to reproduce this bug. I did some investigation and reported it over in Live PXE: Ignition failure: failed to set SSH key: permission denied · Issue #496 · coreos/fedora-coreos-tracker · GitHub.

This was introduced in the latest stable release. Could you use the prior stable release for now?

Thank you for the verification @dustymabe.

I tried 31.20200420.3.0, and it worked great.

Just as an FYI, I tied both 31.20200517.2.0 & 32.20200517.1.0, both gave the same error as before.
CRITICAL : files: createUsers: op(2): [failed] adding ssh keys to user "core": failed to set SSH key: permission denied

31.20200517.2.0, stopped at emergency mode.
32.20200517.1.0, continued after the error to a boot prompt.
