enroot-nsenter: failed to create user namespace: Permission denied

[gagomase]

I’m new to Enroot and Pyxis. When I try to start a container as a regular user, I get the error:
enroot-nsenter: failed to create user namespace: Permission denied.
However, the container runs fine when I use the root account."

can anyone help me with this ?
