6:00 PM [Coke]: I still need to check I think it’s but a Rakudo star issue , it somehow relates to container environment. I see the same problem with whateverable Rakudo and Rakudo installed from source - if they run on container

You need to have the environment variable e.g. $SHELL set to something so it knows what shell to spawn. zef should probably exit with an error stating that.
