LHAPDF files appear to be corrupted

I think we've seen this before:

[INFO]: Could not find a resource (pdf): MMHT2014nnlo68cl. Attempting to download it.

[ERROR]: Resource not in the remote repository: /exports/csce/eddie/ph/groups/nnpdf/Users/wilsonmr/Programs/anaconda/envs/nnpdf/share/LHAPDF/tmpg0_a0exvMMHT2014nnlo68cl.tar.gz is not a compressed or uncompressed tar file. The resource could not be found elsewhere.
[ERROR]: Failed processing key t0pdfset.
[ERROR]: Bad configuration encountered:

Do we need to update the URL or something? Has anybody else seen this problem?
