I'm having this problem in bookworm, even with --no-merged-usr:

$ debootstrap --no-merged-usr sid /var/tmp/chroot/
[...]
I: Unpacking tzdata...
I: Unpacking usr-is-merged...
I: Unpacking zlib1g:amd64...
W: Failure while unpacking required packages.  This will be attempted up to five times.
W: See /var/tmp/chroot/debootstrap/debootstrap.log for details (possibly the package /var/cache/apt/archives/usr-is-merged_38_all.deb is at fault)

Because of this I cannot use pbuilder.
