Source: colorclass Version: 2.2.0-2.1 Severity: serious X-Debbugs-CC: firstname.lastname@example.org Tags: sid bookworm User: email@example.com Usertags: needs-update Control: affects -1 src:python3-defaults Dear maintainer(s),With a recent upload of python3-defaults the autopkgtest of colorclass fails in testing when that autopkgtest is run with the binary packages of python3-defaults from unstable. It passes when run with only packages from testing. In tabular form:
pass fail python3-defaults from testing 3.9.8-1 colorclass from testing 2.2.0-2.1 all others from testing from testingI copied some of the output at the bottom of this report. https://docs.python.org/3.9/library/collections.html says:
"""Deprecated since version 3.3, will be removed in version 3.10: Moved Collections Abstract Base Classes to the collections.abc module. For backwards compatibility, they continue to be visible in this module through Python 3.9.
""" Time to move on.Currently this regression is blocking the migration of python3-defaults to testing . Of course, python3-defaults shouldn't just break your autopkgtest (or even worse, your package), but it seems to me that the change in python3-defaults was intended and your package needs to update to the new situation.
If this is a real problem in your package (and not only in your autopkgtest), the right binary package(s) from python3-defaults should really add a versioned Breaks on the unfixed version of (one of your) package(s). Note: the Breaks is nice even if the issue is only in the autopkgtest as it helps the migration software to figure out the right versions to combine in the tests.
