Singularity Pull Docker Failure

[arianafei]

Hi,

When we type in "singularity pull docker://pennbbl/antssst:0.1.0" as instructed, we get an error saying "While making image from oci registry: error fetching image to cache: failed to get checksum for docker://pennbbl/antssst:0.1.0: reading manifest 0.1.0 in docker.io/pennbbl/antssst: manifest unknown: manifest unknown".

I'm using a Northwestern's computing cluster with singularity installed. Can someone please help me with this issue. It seems as if the antssst image does not exist.

Thank you!
