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

[Mykola Mogylenko]

We faced with totally the same issue. We run PXE Installation on daily
basis as part of our CI/CD Process. It started to fail since Feb 21st.

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.
