[Bug 1816846] Re: segfault in libc-2.23.so netinstall installation pxe

[Nathaniel Priddy]

It looks like it might be related to the fact there there isn't a linux-signed-image-4.4.0-143-generic available? I was able to force it to use the 142 image by setting:
d-i base-installer/kernel/image string linux-image-4.4.0-142-generic

I could set the parameter preseed-kernel-image to linux-
image-4.4.0-142-generic for this to automatically execute. I was then
able to fully image using the xenial-updates.

Title:
  segfault in libc-2.23.so netinstall installation pxe

Status in glibc package in Ubuntu:
  Confirmed

Bug description:
  I have implemented a PXE server in Virtualbox 6.0.4 to perform
  automatic installations of different versions of Linux (particularly
  Ubuntu).

  Until a few hours ago I could perform the automatic installation of
  Ubuntu Server 16.04.5 on a VM, but after updating libc6-udeb
  (2.23-0ubuntu11), I get the following error:

  kernel: [  186.927962] sh[8177]: segfault at 18 ip 00007fc21ff438df sp
  00007ffe594a5e80 error 4 in libc-2.23.so[7fc21ff23000+1c0000]

  I don't know how to fetch the installation log, so I attach a
  screenshot.
