Open /dev/null: permission denied

Hello,

I try to follow the tutorial on https://concoursetutorial.com/.

OS: Linux dvaiaas00b00000 4.15.0-45-generic #48-Ubuntu SMP Tue Jan 29 16:28:13 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

CONCOURSE_WORKER_BAGGAGECLAIM_DRIVER: naive

With command fly -t tutorial execute -c task_hello_world.yml, the result is always runc run: exit status 1: container_linux.go:346: starting container process caused “process_linux.go:449: container init caused “rootfs_linux.go:114: reopening /dev/null inside container caused \“Failed to open /dev/null - open /dev/null: permission denied\”””
errored

Any idea how to solve it?

OK, I’ve just found what is wrong:
I have changed CONCOURSE_WORKER_BAGGAGECLAIM_DRIVER: naive
by CONCOURSE_WORKER_BAGGAGECLAIM_DRIVER: overlay
Naive was tested when pipeline failed on another server with kernel 3.x (before I notice that kernel 4 was mandatory).
This can be closed
