In updating a Bookworm installation from 12.1 to 12.11 I have hit a brick wall during upgrade of libc6 and libc6:i386. The update appeared normal until the upgrade of libc6:i386 (apology offered for the wrap): ------ Preparing to unpack .../20-libc6_2.36-9+deb12u10_i386.deb ... De-configuring libc6:amd64 (2.36-9+deb12u1), to allow configuration of libc6:i386 (2.36-9+deb12u10) ... Unpacking libc6:i386 (2.36-9+deb12u10) over (2.36-9+deb12u1) ... Preparing to unpack .../21-libc6_2.36-9+deb12u10_amd64.deb ... Unpacking libc6:amd64 (2.36-9+deb12u10) over (2.36-9+deb12u1) ...

I have set up the failed image in a chroot environment, and tried replacing ld-linux-x86-64.so.2 in what I assume is its correct location - /usr/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2 This allows bash to start, but other commands still fail, now with segmentation faults: root@recovery:~# chroot /mnt /bin/bash --login bash: [: : integer expression expected root@recovery:/# ll Segmentation fault root@recovery:/# pwd / root@recovery:/# hostname Segmentation fault root@recovery:/# exit logout root@recovery:~# pwd /root root@recovery:~# hostname recovery root@recovery:~# I would be grateful for suggestions for repair of the exiting image. The filesystem is ZFS and I havce two full snapshots: immediately after the original Bullseye installation and immediately after the upgrade to Bookworm, and have enough backups to restore user data from either point along with information to reinstall all packages. A quick repair would be nice, but if it's too involved or uncertain, I can reinstall. Thanks in advance for any suggestions. Tom Dial a) roll back to the initial install (Bullseye) and update/upgrade from that; or b) clear the disk and reinstall everything
