duplicity 1.2.1 incompatible with python3.12

[adud]

Is this a new report?

Yes

System Info

Void 6.5.6_1 x86_64 GenuineIntel uptodate rFFFF

Package(s) Affected

duplicity-1.2.1_3

Does a report exist for this bug with the project's home (upstream) and/or another distro?

No response

Expected behaviour

The package is supposed to do backups

Actual behaviour

Any call to duplicity results in the following python error

Traceback (most recent call last):
  File "/usr/bin/duplicity", line 30, in <module>
    from future import standard_library
  File "/usr/lib/python3.12/site-packages/future/standard_library/__init__.py", line 65, in <module>
    import imp
ModuleNotFoundError: No module named 'imp'

The bug comes from the future package, which uses the imp module (removed in python 3.12). The use of this package has been removed since duplicity 2.0.0 (https://gitlab.com/duplicity/duplicity/-/blob/main/CHANGELOG.md) while dropping python2.7 support

This could explain the failure in #46170
