Keeping reference of this issue for future wanderers:

ref1: ContinuumIO/anaconda-issues#11163 ref2: sylabs/singularity#875

solution(s):

• use an older miniconda installer: version 4.6.14
• add -B /run/shm:/run/shm when running the singularity container (not a good solution when trying to install miniconda

The singularity issue for the miniconda test appears to be related to ContinuumIO/anaconda-issues#11163
