Package: debootstrap
Version: 1.0.114
Severity: normal
I'm struggling with a problem that I currently have with debootstrapping an
arm64 system on my amd64 machine. The attached script can reproduce the issue
here.
It crashes here on a debian buster amd64, in the 2nd debootstrap stage:
...
W: Failure trying to run: /sbin/ldconfig
W: See //debootstrap/debootstrap.log for details

It works if I debootstrap a buster system instead. Then trying to upgrade to
bullseye in the same chroot crashes with a segfault during the upgrade of libc-
bin. It also segfaults when I just open a chrooted shell after the 1st stage
and then run "ldconfig". That worked here around new year, but then broke.
This looks like a software bug somewhere. I'm not sure if I'm right here. But
maybe you can tell me.
