Comment 7 for bug 1964285

@Yuhua,
hello this is really odd.
Until one can hopefully reproduce this soon on our side could you also run this in the failing environment?

  dpkg -S /usr/sbin/policy-rc.d

Because as far as I can see in the archive all that could exist is this list:

root@j:~# apt-file search policy-rc.d
fai-nfsroot: /usr/bin/policy-rc.d.fai
init-system-helpers: /usr/share/doc/init-system-helpers/README.policy-rc.d.gz
livecd-rootfs: /usr/share/livecd-rootfs/live-build/buildd/includes.chroot/usr/local/sbin/policy-rc.d
policy-rcd-declarative: /usr/sbin/policy-rc.d-declarative
policy-rcd-declarative: /usr/share/man/man8/policy-rc.d-declarative.8.gz
policyrcd-script-zg2: /usr/sbin/zg-policy-rc.d
policyrcd-script-zg2: /usr/share/man/man8/zg-policy-rc.d.8.gz

Hence I was totally ok with Parides question, but now that you see this again we need to find what/where it comes from.
The command above will try to tell you which package installed that file.

That ISO you mean is that a modified/adapted version or plain
https://cdimage.ubuntu.com/daily-live/current/jammy-desktop-amd64.iso
from
https://cdimage.ubuntu.com/daily-live/current/
?
