Would you consider packaging vl-convert-python to support the simplified save to PNG process introduced in Altair 5?

Oh, it is indeed an upstream bug, but as I'm not really versed in the new python build-system I refrained from opening a ticket until I knew what went wrong in which place.
So thanks for the pointer in which step this gets added. As far as I can currently tell, this is for the tool coming from python-hatchling. Imo those lines should simply be removed. The LICENSE file gets already added to another location related to site-packages. Therefore it is already covered. The .toml isn't needed for the finished package and dunno if there is a doc dir where the README can be additionally placed.
Now it should be enough information that I can take it later to uptream.

I suppose it's an upstream bug for the other package, so I was (and am) just planning to report it to upstream.

But it seems that it's also the case for this package...
https://github.com/altair-viz/altair/blob/f3ced05897cb1e17f7299086436c0a08348c7028/pyproject.toml#L97-L99 I wonder how should include be used.

With -2 the issue is fixed.
One note though: As there was for you already a LICENSE file installed in that location, I would suggest (if not already done) to report this additionally for the other package in question. In that location there shouldn't be such files.

Definitely shouldn't be there. Will take a look. Thanks for reporting.

python-altair: /usr/lib/python3.11/site-packages/LICENSE exists in filesystem (owned by xxx)

LICENSE, README.md and pyproject.toml in /usr/lib/python3.11/site-packages. Something wrong?

What is your build environment revan? Any AUR helper? Or building with a clean chroot?
I can only say, I can build this package sucessfully

Trying to update from 4.2.0-2 to 4.2.2-1 fails for me with the following traceback:

Does anybody else receive this errors or has an idea what the problem might be?

Valid point lilydjwg. That needs to be adjusted. Thanks for checking :)
