Tests fail on main due to a fiona/geopandas error

[binste]

What happened?

Tests fail, see e.g. https://github.com/vega/altair/actions/runs/9005770219/job/24850952007#step:9:67

I'll look into it. Can't replicate this on my Mac so far.

What would you like to happen instead?

No response

Which version of Altair are you using?

No response

[mattijn]

It's because of this line: https://github.com/vega/altair/blob/main/tests/examples_methods_syntax/interval_selection_map_quakes.py#L14

gdf_quakies = gpd.read_file(data.earthquakes.url, driver="GeoJSON")

Maybe a glitch or something changed in geopandas?

[binste]

No new version of geopandas and fiona in the last few days and it only happens for Python 3.11 (consistently across reruns):

I can't replicate this with Python 3.11 on Debian and I struggle to install Fiona on the same Ubuntu version as the GitHub runners use.

Maybe some change in a system dependency such as gdal? As it's not related to Altair and it's not blocking any major developments, we could wait a few days to see if this gets resolved somewhere upstream.

UPDATE: In #3419 it happened for Python 3.12...

[mattijn]

Raised geopandas/geopandas#3284 at the geopandas repo.

[mattijn]

Temporarily fixed by #3421

Thanks @mattijn! Also for engaging in the geopandas discussion.

Reopening, see geopandas/geopandas#3284 (comment).
