Title:
  Upgrade from Jammy to Noble breaks

Status in dash package in Ubuntu:
  Fix Committed

Bug description:
  Hello there!

  Upgrading `dash` from Jammy to Noble is broken. Here is a quick
  reproducer:

  ```
  podman pull ubuntu:jammy
  podman run -it --rm  ubuntu:jammy
  sed -i 's/jammy/noble/' /etc/apt/sources.list
  apt update
  apt full-upgrade
  ```
  This should end up with this error:
  ```
  Setting up dash (0.5.12-6ubuntu3) ...
  Removing 'diversion of /usr/share/man/man1/sh.1.gz to /usr/share/man/man1/sh.distrib.1.gz by dash'
  Removing 'diversion of /bin/sh to /bin/sh.distrib by dash'
  This should never be reached
  dpkg: error processing package dash (--configure):
   installed dash package post-installation script subprocess returned error exit status 1
  Errors were encountered while processing:
   dash
  E: Sub-process /usr/bin/dpkg returned an error code (1)
  ```

  As `dash` is pre-installed on almost every kind of Ubuntu, this breaks
  any upgrade from Jammy to Noble in practice.
