chmod: changing permissions of '/app/.env': Operation not permitted

[LvK8]

When I use the docker cp command to copy to the docker modified. Env file, and then copy to the Docker in the same way, the container will not start. Docker: chmod: changing permissions of '/app/. Env ': Operation not permitted

Just change the ownership to the uid/gid that huginn docker uses before docker cp your file into docker. chown 1001:0 .env
