Were you able to resolve it? I have the same issue

Ubuntu 18.04.6 LTS (bionic)
ml-agents: 0.27.0
ml-agents-envs: 0.27.0
Communicator API: 1.5.0
PyTorch: 1.8.1+cu102

Found the issue. Try running

setfacl -R -b

where “” is the directory with the build. It might have the special access privilege set.

I encountered the same problem. I used the command line to package apk. My problem was that I mistakenly entered the path of unity.exe “Applications/Unity/2020.3.30f1/Unity.app/Contents/MacOS/Unity -batchmode”. The correct one should be “Applications/Unity/Hub/Editor/2020.3.30f1/Unity.app/Contents/MacOS/Unity -batchmode”, so I solved it.
