According to https://docs.python.org/3.13/whatsnew/3.13.html:
PEP 594: Remove the telnetlib module, deprecated in Python 3.11: use the projects telnetlib3 or Exscript instead.
(Contributed by Victor Stinner in gh-104773.)

For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.13/fedora-rawhide-x86_64/06564744-python-pytn3270/

For all our attempts to build python-pytn3270 with Python 3.13, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.13/package/python-pytn3270/

Testing and mass rebuild of packages is happening in copr.
You can follow these instructions to test locally in mock if your package builds with Python 3.13:
https://copr.fedorainfracloud.org/coprs/g/python/python3.13/

Let us know here if you have any questions.

Python 3.13 is planned to be included in Fedora 41.
To make that update smoother, we're building Fedora packages with all pre-releases of Python 3.13.
A build failure prevents us from testing all dependent packages (transitive [Build]Requires),
so if this package is required a lot, it's important for us to get it fixed soon.

We'd appreciate help from the people who know this package best,
but if you don't want to work on this now, let us know so we can try to work around it on our side.

Comment 1 Aoife Moloney 2024-02-15 23:02:02 UTC
This bug appears to have been reported against 'rawhide' during the Fedora Linux 40 development cycle.
Changing version to 40.

Comment 3 Fedora Fails To Install 2024-06-19 19:56:49 UTC
Hello,

Please note that this comment was generated automatically by https://pagure.io/releng/blob/main/f/scripts/ftbfs-fti/follow-policy.py
If you feel that this output has mistakes, please open an issue at https://pagure.io/releng/

This package fails to install and maintainers are advised to take one of the following actions:

 - Fix this bug and close this bugzilla once the update makes it to the repository.
   (The same script that posted this comment will eventually close this bugzilla
   when the fixed package reaches the repository, so you don't have to worry about it.)

or

 - Move this bug to ASSIGNED if you plan on fixing this, but simply haven't done so yet.

or

 - Orphan the package if you no longer plan to maintain it.


If you do not take one of these actions, the process at https://docs.fedoraproject.org/en-US/fesco/Fails_to_build_from_source_Fails_to_install/#_package_removal_for_long_standing_ftbfs_and_fti_bugs will continue.
This package may be orphaned in 7+ weeks.
This is the first reminder (step 3) from the policy.

Don't hesitate to ask for help on https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/ if you are unsure how to fix this bug.

Comment 4 Karolina Surma 2024-09-04 15:02:50 UTC
This package has failed to build with Python 3.13 so far. Fedora 41 is already in the Beta Freeze phase. What's your plan going forward? Will the package be fixed in time for the Final Freeze of Fedora 41 (planned on Oct 15th 2024)?
If you don't plan or can't fix the package before Fedora 41 goes into the Final Freeze phase, please retire the package. You can unretire it anytime during the Fedora 41 lifecycle - doing this now will simply ensure that we don't release Fedora with a broken package. Thank you!

Comment 5 Davide Cavalca 2024-09-28 22:21:09 UTC
Working on this now, need to package telnetlib3 first to unbreak this.
