Trying to install SearXNG Docker on Linux Mint

[logan683]

I was able to get this working the other day, but I needed to delete the container and remake it. Now I get the following error:

Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: error mounting "/usr/local/searxng-docker/Caddyfile" to rootfs at "/etc/caddy/Caddyfile": create mountpoint for /etc/caddy/Caddyfile mount: cannot create subdirectories in "/var/lib/docker/rootfs/overlayfs/305ef18d9928c7df12165987aff9fffc8d58216d09e29692717cdbfb53092258/etc/caddy/Caddyfile": not a directory: unknown: Are you trying to mount a directory onto a file (or vice-versa)? Check if the specified host path exists and is the expected type

I'm literally following the listed instructions step by step. I don't have a lot of experience with these things, especially Linux.

How can I correct this error?

Thank you very much.
