Bug: Some tests fail if inetutils-inetd isn't installed on Ubuntu #1654
Description
Describe the bug
Some tests fail if inetutils-inetd isn't installed on Ubuntu
When building Python 3.13.7 from source, two socket tests fail if inetutils-inetd isn't installed.
Steps to Reproduce
The following Dockerfile gives a reproducible demonstration, making sure this works in Ubuntu 22.04 and Fedora 24:
ARG UBUNTU=ubuntu:24.04@sha256:d0afa9fbcf16134b776fbba4a04c31d476eece2d080c66c887fdd2608e4219a9

ENTRYPOINT [ "/usr/local/bin/python3/python" ]To run it, in your project directory, run:
docker build -t python_ubuntu --target=python_ubuntu . && docker run --rm -it python_ubuntu:latest or
docker build -t python_fedora --target=python_fedora . && docker run --rm -it python_fedora:latest to use Ubuntu or Fedora, respectively. This change only applies to the Ubuntu image, so running Fedora is not necessary to verify it, but rather it's here for completeness. Together, these sanity-check apt-get and dnf.
Actual behavior
- Fedora runs Python 3.13.7.
- If
inetutils-inetd \is commented out, the following tests fail the Python build in Ubuntu, aborting the overall image build:test.test_asyncio.test_base_events test_socket. Python 3 on Linux implicitly depends on one of the following services to be installed:daytime,qotdordomain. For reference, the CPython 3.13.7 source code.
Expected behavior
- Fedora runs Python 3.13.7.
- If
inetutils-inetd \is not commented out, all three services are installed, and Ubuntu runs Python 3.13.7.

Thank you for the report and fix!
Note that the "full list" of dependencies is meant to be used instead of
build-dep; you don't need both. (But you might want both: withbuild-depthe Ubuntu maintainers will keep the list updated for you, while the Devguide list apparently has additional test dependencies.)
