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":

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.


try this
But, make a backup of your db beforehand. I don’t know how it would work when upgrading an existing database
