This prevents the latest version of matrix-synapse from building.
Comment 1 Gwyn Ciesla 2021-04-27 20:51:38 UTC 
This also prevents the current version of matrix-synapse from running.
Comment 2 Gwyn Ciesla 2021-04-27 20:56:35 UTC 
Updating python3-treq to a build of 21.1.0 from rawhide for f34 fixes synapse.
Comment 3 Kai A. Hiller 2021-07-03 22:03:26 UTC 
Please update python-treq to 20.9.0 or newer for Fedora 34 so we can update matrix-synapse to its newest version.
