See also https://bugzilla.redhat.com/show_bug.cgi?id=2250331#c3 for details. The upstream fix is here: https://github.com/ronf/asyncssh/commit/0bc73254f41acb140187e0c89606311f88de5b7b It cherry-picks cleanly for epel9: https://src.fedoraproject.org/rpms/python-asyncssh/pull-request/7 I've built that PR 7 here for early testing: https://copr.fedorainfracloud.org/coprs/ktdreyer/asyncssh/ I'm updating this bug to only track the EPEL 9 fix. EPEL 8 will remain unfixed. FEDORA-EPEL-2024-6bc0ac05e1 (python-asyncssh-2.13.2-5.el9) has been submitted as an update to Fedora EPEL 9. https://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2024-6bc0ac05e1 FEDORA-EPEL-2024-6bc0ac05e1 has been pushed to the Fedora EPEL 9 testing repository. You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2024-6bc0ac05e1 See also https://fedoraproject.org/wiki/QA:Updates_Testing for more information on how to test updates. FEDORA-EPEL-2024-6bc0ac05e1 (python-asyncssh-2.13.2-5.el9) has been pushed to the Fedora EPEL 9 stable repository. If problem still persists, please make note of it in this bug report. |
