[Bug 1951993] [NEW] aptdaemon FTBFS with python3.10

[Gunnar Hjalmarsson]

Public bug reported:

This is the buildlog from the 1.1.1+bzr982-0ubuntu37 upload:

https://launchpadlibrarian.net/570420275/buildlog_ubuntu-jammy-
amd64.aptdaemon_1.1.1+bzr982-0ubuntu37_BUILDING.txt.gz

This error:

  File "/usr/lib/python3/dist-packages/defer/__init__.py", line 263, in add_callbacks
    assert isinstance(callback, collections.Callable)
 AttributeError: module 'collections' has no attribute 'Callable'

happens repeatedly and results in 15 failed tests.

The same source builds successfully in a PPA which uses packages from
jammy-release, so I suppose it's a python3.10 issue.

Brutally disabling the tests makes it build in a jammy-proposed
environment:

https://launchpad.net/~gunnarhj/+archive/ubuntu/aptdaemon2/+packages

But probably there is a more proper solution.

** Affects: aptdaemon (Ubuntu)
     Importance: High
         Status: New
