Answer 1

Try to run using sudo ./run_all.sh and let me know

Answer 2

For anyone else that arrives at this question using RHEL or Centos, I had the same issue with RHEL 7.3

Apparently In older RHEL kernel versions they deny creation of mount namespaces inside a user namspace because of an out-of-tree patch. apparently RHEL 7.5 will fix this.

I updated my OS to 7.9 and it resolved the issue:

Check for updates:

yum check-update

Update the system

yum update

And then reboot

reboot 

After this follow the instructions as documented running as sudo.
