FATAL: while extracting hyper_lite__0_1.sif: root filesystem extraction failed: extract command failed: FATAL: container creation failed: multiple devpts instances unsupported and /dev/pts configured : exit status 255 ``` This is my singularity command (mounting current working directory, x509 proxy location and cvmfs): ``` $SINGULARITY_BIN run --contain --env X509_USER_PROXY=${X509_USER_PROXY} \ -B $PWD -B $X509_USER_PROXY -B /cvmfs \ $LOCAL_IMAGE /bin/sh -l $JOB_SCRIPT ``` Also by default i'm using `/cvmfs/ oasis.opensciencegrid.org/mis/singularity/current/bin/singularity` for the singularity binary, unless user namespaces aren't enabled on that system and then it uses the local singularity instead. I wonder if the issue is with something i'm mounting or is it something else?
