Description Miro Hrončok 2020-03-26 17:38:02 UTC
sugar-paint fails to build with Python 3.9.0a5.


+ python3 ./setup.py build
Traceback (most recent call last):
  File "/builddir/build/BUILD/Paint-70/./setup.py", line 19, in <module>
    from sugar3.activity import bundlebuilder
  File "/usr/lib/python3.9/site-packages/sugar3/activity/bundlebuilder.py", line 44, in <module>
    import xml.etree.cElementTree as ET
ModuleNotFoundError: No module named 'xml.etree.cElementTree'

See https://docs.python.org/3.9/whatsnew/3.9.html#removed

"The xml.etree.cElementTree module has been removed."


For the build logs, see:
https://copr-be.cloud.fedoraproject.org/results/@python/python3.9/fedora-rawhide-x86_64/01321121-sugar-paint/

For all our attempts to build sugar-paint with Python 3.9, see:
https://copr.fedorainfracloud.org/coprs/g/python/python3.9/package/sugar-paint/

Testing and mass rebuild of packages is happening in copr. You can follow these instructions to test locally in mock if your package builds with Python 3.9:
https://copr.fedorainfracloud.org/coprs/g/python/python3.9/

Let us know here if you have any questions.

Python 3.9 will be included in Fedora 33. To make that update smoother, we're building Fedora packages with early pre-releases of Python 3.9.
A build failure prevents us from testing all dependent packages (transitive [Build]Requires), so if this package is required a lot, it's important for us to get it fixed soon.
We'd appreciate help from the people who know this package best, but if you don't want to work on this now, let us know so we can try to work around it on our side.

A patch has been sent upstream, once that is merged it'll be updated downstream.
