You can write the ACIS file to disk, but the ACIS write to the cub5 file terminates prematurely. I can’t easily look at the .cub file, but the assumption is that the ACIS file there is also corrupted. Do you have anything in your path that could cause problems? Maybe something using a different version of HDF5 or maybe old versions of Cubit?
I am using Docker on Ubuntu 18.06 LTS. I am not an expert on it, but I assume that all the proper dependencies should be contained in the image that I installed.
Let me know if you need me to check anything specifically.
