I am trying to create a Nextcloud container, but it is saying it is not permitted to mknod urandom and random. I don't know what this means, but I am having trouble finding the solution. I do not know what you need to know to help me, so please let me know.
Thanks in advance.

Seem the template contains urandom device nodes. An unprivileged container is not allowed to create such device nodes.
