I have been hitting this bug today using xenial flavor of ubuntu over PXE. The bug is mentioned in this mailing list message (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=833706#45), basically it is probably better to call the netboot image from the *-updates directory for the ubuntu family in src/ubuntu.ipxe. Example : http://archive.ubuntu.com/ubuntu/dists/xenial-updates/main/installer-amd64/current/images/netboot/ubuntu-installer/amd64/ - > http://archive.ubuntu.com/ubuntu/dists/xenial-updates/main/installer-amd64/current/images/netboot/ubuntu-installer/amd64/

Yeah, I was running into this elsewhere this week. I've bumped them to using the updates kernels, altho that may break signature checking more often since they rotate out those kernels and don't have that directory structure versioned.

So what would be the workaround when hitting this bug while using netboot.xyz ? 16.04 has been broken for more than one day now.
