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

[Michael Hudson-Doyle]

I'm not an expert in this bit of the installer, but it seems to me that
the problem is that installation using older kernel/initrd is what is
failing. If you download the initrd/kernel from
http://archive.ubuntu.com/ubuntu/dists/xenial-updates/main/installer-
amd64/current/images/netboot/ubuntu-installer/amd64/ today, it works.
Can someone who is experiencing the problem post the SHA1 of their
initrd/kernel?

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.
