I'm trying to follow the guide here https://join-lemmy.org/docs/administration/install_docker.html

I get an error when I run docker compose up -d. It happens after docker outputs ⠹ Container lemmy-postgres-1 Starting

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 "/home/user/lemmy/volumes/postgres" to rootfs at "/var/lib/postgresql/data":
change mount propagation through procfd: open o_path procfd: open /var/lib/docker/

var/lib/postgresql/data: no such file or directory: unknown

I'm not really sure what this means, and trying all of AIs suggestions didn't fix it.

I'm kinda new to all of this, so any help would be appreciated.

Understandable, I will say you definitely chose to dive straight into the deep end choosing Lemmy 🤣 I think most people cut their teeth using docker on stuff like Plex and the related *arrs, then jump to the more complex stuff.

But, it's also the best way to learn so enjoy it :) stuff like this will become trivial eventually
