I never encountered it before and have failed to google my way out yet. @asmacdo - any ideas or experiences like this in the past?

[asmacdo]

what command did you use to run this? to me it looks like something is attempting to pull from an image registry but the request isn't right.

[asmacdo]

Heres my guess from only briefly reading over the relevant code: When we don't already have the image singularity should pull docker://djareka/fakemri_prep. However, the Content-Headers requirement (IIRC) is relatively new.

Do you happen to have singularity 2.6?

Apparently that doesnt work :) https://github.com/ReproNim/containers/blob/master/scripts/create_singularities#L332-L333

If that's the problem (or close), the workaround should be to docker pull djareka/fakemri_prep before you run this command.

[yarikoptic]

Thanks for looking into it. it is indeed the "good old" 2.6.1-dist singularity on smaug. I kept it that old to provide maximal compatibility with newer ones since new singularity could read it but old could not read new images

[asmacdo]

If you're interested in extra details, heres docs for the registry v2 API call that uses the accept headers (added 2016 or so)
