22.04.2 "unable to find livesystem on network" with IPXE install

[sascha arthur]

Hello,

we using following ipxe script to run the ubuntu autoinstaller:

kernel vmlinuz initrd=initrd keyboard-configuration/layoutcode=de root=/dev/ram0 ramdisk_size=1500000 ip=dhcp url=http://releases.ubuntu.com/22.04/ubuntu-22.04.2-live-server-amd64.iso autoinstall ds=nocloud-net;s=.../ cloud-config-url=.../user-data hwaddr=92:01:00:00:00:02
initrd initrd
boot

initrd/vmlinuz we extracting out of the iso, whenever theres an update.

Since 22.04.2 the process is broken. Its stuck in "unable to find livesystem on network". tested on multiple hosts, working smoothly on 22.04.1. What could have broken this ipxe autoinstaller? any workarrounds?

Thanks for the report Sascha.

I've updated the title, as I confirmed that not every case of autoinstall is broken.

I believe the "unable to find livesystem on network" prompt is in casper, perhaps something went wrong with acquiring the network there.

It seems to fail on "mounting" the iso and executing the autoinstall procedure. Even though it downloaded the iso (inside of the ramfs), it fails to proceed further...

Are you completely sure that your initrd came out of the ISO you are presenting? That would be the most straightforward explanation for the behaviour you are seeing.

yes, im extracting it on the fly.
