Title:
  Crash during upgrade from Mantic to Noble due to Python 3.12

Status in apt-xapian-index package in Ubuntu:
  New
Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  Upgrading from Mantic to Noble often triggers a crash related to Python 3.12 compatibility:
  ```
  Traceback (most recent call last):
    File "/usr/sbin/update-apt-xapian-index", line 66, in <module>
      import axi.indexer
    File "/usr/lib/python3/dist-packages/axi/indexer.py", line 27, in <module>
      import imp
  ModuleNotFoundError: No module named 'imp'
  ```

  I guess that the crash happens when the indexer code is called while
  still being in the Mantic version, but the default Python3 package has
  already been upgraded to 3.12. However, that situation doesn't happen
  all the time, and the upgrade is sometimes able to complete without
  crash.

  For some reasons, I mostly (only?) see this on Kubuntu upgrades.

  Maybe that situation could also happen while upgrading from Jammy, but
  as the upgrade is currently broken due to some other issues, I haven't
  seen it yet.
