Comment 1 Miro Hrončok 2019-07-10 10:40:12 UTC
Please respond.

Comment 2 Eric Smith 2019-07-26 04:45:29 UTC
Waiting on upstream to support Python 3.8

Comment 3 Ben Cotton 2019-08-13 16:57:33 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 31 development cycle.
Changing version to '31'.

Comment 4 Ben Cotton 2019-08-13 18:54:42 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 31 development cycle.
Changing version to 31.

Comment 5 Miro Hrončok 2019-08-14 22:24:54 UTC
The coordinated rebuild of Python 3.8 has started in the `f32-python` side tag.

If you figure out how to rebuild this package, please don't rebuild it in regular rawhide, but use the side tag instead:

    on branch master:
    $ fedpkg build --target=f32-python

To wait for a build to show up in the side tag, do:

    $ koji wait-repo f32-python --build=<nvr>

Where <nvr> is name-version-release of the source package, e.g. python-foo-1.1-2.fc32.

An updated mock config is posted at:

Note that it will take a while before the essential packages are rebuilt, so don't expect all your dependencies to be available right away.

Thanks. Let us know if you need up to date info, or if you have any questions.

PS this message is mass posted to all the bugs that block the PYTHON38 bug. If this is also a Fedora 31 FTBFS bug and you manage to fix it, you can do a f31 build as usual:

    on branch f31:
    $ fedpkg build

Comment 6 Miro Hrončok 2019-08-21 16:35:40 UTC
The f32-python side tag has been merged. In order to rebuild the package, do it in regular rawhide, but please wait until python3-3.8 is tagged:

  $ koji wait-repo f32-build --build python3-3.8.0~b3-3.fc32

If your built already started in f32-python, after it is finished, please tag it to rawhide with:

  $ koji tag-build f32-pending <nvr>

For example:

  $ koji tag-build f32-pending libreoffice-

Comment 7 Miro Hrončok 2019-08-21 17:29:38 UTC
(Python 3.8 has landed in the rawhide buildroot.)

Comment 8 Miro Hrončok 2019-09-16 08:05:52 UTC
This issue is blocking the Python 3.8 rebuilds. If this package won't build with 3.8, it won't be installable, along with all its dependent packages, in Fedora 32.
Furthermore, as it fails to install, its dependent packages will fail to install and/or build as well.

If upstream isn't Python 3.8 ready, could you please open an issue with them?

Comment 9 Felix Schwarz 2019-11-08 08:21:46 UTC
Upstream added Python 3.8 compatibility

Comment 10 Miro Hrončok 2019-12-26 13:00:23 UTC
Automation has figured out the package is retired in rawhide.

If you like it to be unretired, please open a ticket at

Comment 11 Red Hat Bugzilla 2023-09-14 05:27:59 UTC
The needinfo request[s] on this closed bug have been removed as they have been unresolved for 1000 days
