Singularity image download error

[fmalmeida]

Sometimes when downloading the docker image for singularity with:

singularity pull --dir $NXF_SINGULARITY_LIBRARYDIR docker://fmalmeida/mpgap:v3.1

You may receive the following error:

FATAL:   While making image from oci registry: error fetching image to cache: while building SIF from layers: conveyor failed to get: Error initializing source oci:/home/falmeida/.singularity/cache/blob:c851ad48e8c6310862c8b1f628e9406da818b66e0773fe8a7ea2b31688a57cfd: Error reading blob sha256:d6e7252e7dfbd57c1675aaefdbb56ae27f20aa6c61d87ff0d77ab8d8252f677c: unable to retrieve auth token: invalid username/password: errors:

Please, do not panic, this also happens with docker sometimes. Your server only have closed the connection because it was taking too long.

Just execute the command again, without changing anything, and singularity with use its download caches, skipping previous layers downloaded, and will properly finish the .sif image creation.
