Package: libc-bin
Version: 2.31-11
Severity: important
X-Debbugs-Cc: rand...@mason.ch
Dear Maintainer,
* What led up to the situation?
I run a CI build of images for my raspberry pi with the upstream
kernel and debian userspace. I use qemu-debootstrap. At some point
the builds stopped working for bullseye and sid. The host of the
qemu-debootstrap is either Ubuntu 18.04 or 20.04, the only debian
based options on Github Actions.
* What exactly did you do (or not do) that was effective (or
ineffective)?
I ended up pinning the build to snapshot 20210103T144403Z as that
works on both bullseye and sid. On first boot I use cloud-init to
update packages if connected to network.
* What was the outcome of this action?
I'm no longer getting up to date debian when I load a new image on
my Raspberry Pi. If networking is down on first boot, I'm stuck
at an old version of debian.
* What outcome did you expect instead?
I'd hope to be able to continue building bulleye and sid images.
I did a bisect using snapshot and the last working version was that
snapshot and the only change to base debootstrap packages was updating
from libc 2.31-6 for both bullseye and sid. I tested sid, as there are
more versions between 6 and 11 released and it broke immediately on
2.31-7. Looking at the changelog I would guess that it's
https://salsa.debian.org/glibc-team/glibc/-/commit/ac2dc2a2df164509bfa35b2e8181606510baa123
that broke the qemu-debootstrap. Here are some example segfaults:
When bootstrapping from latest repos:
I: Running command: chroot /mnt /debootstrap/debootstrap --second-stage
W: Failure trying to run: /sbin/ldconfig
W: See //debootstrap/debootstrap.log for details

When bootstrapping from the above snapshot and then upgrading during
the bootstrap:
