That is python-chameleon-3.4-2.fc31. This blocks the bootstrap of Python 3.8.
This is needed by pyramid and hence bodhi - setting high severity.
Comment 1 Miro Hrončok 2019-04-04 14:47:12 UTC 
I got to pyramid in in bootstrap sequence. Can we try to get chameleon updated? Recent upstream is 3.6.1 from this Monday.
Comment 2 Miro Hrončok 2019-04-04 14:50:57 UTC 
Running tox on upstream checkout reveals that 3.4 fails but 3.6.1 passes.
Comment 3 Miro Hrončok 2019-04-04 14:52:54 UTC 
Git bisect gives: https://github.com/malthe/chameleon/pull/273 Add support for Python 3.8

That is included since 3.5.
Comment 4 Miro Hrončok 2019-04-09 17:33:24 UTC 
Fixed in git.
