Netboot installer appears broken in utopic

[yoshi314]

i boot ubuntu installer through iPXE like so :

#!ipxe
dhcp

set 210:string http://archive.ubuntu.com/ubuntu/dists/utopic/main/installer-amd64/current/images/netboot/
chain ${210:string}pxelinux.0

This worked perfectly with trusty, fails on utopic due to "cannot load ldlinux.c32" error (file is present on the server). On both architectures.

My take is that it's a pxelinux bug, although i found reports on it on other pxelinux versions, and not this one.

Steps to reproduce

- build ipxe from source with make EMBED=menu ; where menu contains the aforementioned content
- boot in qemu (qemu-system-x86_64 -kernel bin/ipxe.lkrn ) , obseve the problem
- s/utopic/trusty/g
- rebuild ipxe
- observe correct boot in qemu

Status changed to 'Confirmed' because the bug affects multiple users.

Is there any way you could take a packet capture so that we can find out what path the ldlinux.c32 file is attempted to retrieve from?

Thanks!

I can give it a shot in a few days. Loading older pxelinux and pointing it to current configs seems to resolve the issue.

#!ipxe

  dhcp
  set 210:string http://archive.ubuntu.com/ubuntu/dists/utopic/main/installer-i386/current/images/netboot/
# chain ${210:string}pxelinux.0
  chain http://archive.ubuntu.com/ubuntu/dists/trusty/main/installer-i386/current/images/netboot/pxelinux.0

The vesamenu.c32 cannot be loaded due to incompatibility, so there is only text-mode menu prompt from pxelinux. But system is installable this way.
