Maybe the file had issues during the download ? Could you try to delete your cache and try again ? By default the downloads cache is at ~/.cache/huggingface/datasets/downloads

Also can you check if you have a proxy that could prevent the download to succeed ? Are you able to download those files via your browser ?

I also can’t reproduce the error on Windows/Linux (tested both the master and the 1.15.1 version).
