Fixes #6282
We install a package
dask-core
but then in CI later uninstall one calleddask
. That might not have been caught before becausedask
was being pulled in as a transitive dependency of something else (unsure).Anyway, now that it isn't,
conda uninstall dask
fails with the error shown in the linked issue.This resolves it by explicitly uninstalling
dask-core
.
