The test is failing since s3fs got upgraded to 0.5.2 in our pipelines. On master this was first the case for 396131a. The commits before that had 0.4.2. I don't know why this happend yesterday since the packages seems to be up on conda forge for a month (https://anaconda.org/conda-forge/s3fs/files) but installing a new environment and downgrading s3fs to 0.4.2 locally causes the test to pass while it fails with 0.5.2

[phofl]

I am removing unreliable test, since this is a dependency issue

[phofl]

We are somehow pulling s3fs=0.4.2 again, so tests are passing now, meaning xfail causes bugs.

[jbrockmendel]

is there a relevant issue on the s3fs tracker?

[jbrockmendel]

@martindurant looks like you did a lot of work on these tests. any idea how to fix them now?

[mroeschke]

I think these have been fixed by running these tests in single cpu builds so closing
