Created attachment 1782763 [details] Traceback Description of problem: On twisted 21.2.0-2.fc34, matrix-synapse fails to start. The version of python3-twisted in the .spec file should probably set to >= 18.9.0, < 21.0.0 until twisted 21 is supported. Version-Release number of selected component (if applicable): matrix-synapse 1.26.0-1.fc34 python3-twisted 21.2.0-2.fc34 How reproducible: Reproduced on x86 and aarch64 Steps to Reproduce: 1. Install packages 2. systemctl start synapse Actual results: Service fails to start, with traceback attached. Expected results: Service starts successfully. Additional info: The problem is resolved if packages python3-twisted-20.3.0-5.fc34 and python3-twisted+tls-20.3.0-5.fc34 are installed instead.
This was a bug in python-treq, not in synapse itself. *** This bug has been marked as a duplicate of bug 1953535 ***
