SOLVED: unable to find user in passwd file (docker compose)

[Pollo]

Hello! I am trying to set up docker and after using the documentation for docker compose setup, I'm getting this error when I try to start the container with docker compose up:

"Error response from daemon: unable to find user pete: no matching entries in passwd file"

I don't understand why i'm getting this error because my user is in the passwd file already. I am running the latest stable build of the Ubuntu docker container runtime (27.2.0). Here is my docker-compose.yml file:

Code:

services:
  jellyfin:
    image: 'jellyfin/jellyfin:latest'
    container_name: jellyfin
    user: pete:pete
    network_mode: 'host'
    ports:
    - 8096:8096
    volumes:
      - /var/snap/docker/common/var-lib-docker/volumes/jellyfin-config:/config
      - /var/snap/docker/common/var-lib-docker/volumes/jellyfin-cache:/cache
      - type: bind
        source: /media/pete/{media dir}
        target: /media
      #- type: bind
        #source: /path/to/media2
        #target: /media2
        #read_only: true
      # Optional - extra fonts to be used during transcoding with subtitle burn-in
      - type: bind
        source: /home/pete/snap/docker/jellyfin/fonts
        target: /usr/local/share/fonts/custom
        read_only: true
    restart: 'unless-stopped'
    # Optional - alternative address used for autodiscovery
    #environment:
      #- JELLYFIN_PublishedServerUrl=http://example.com
    # Optional - may be necessary for docker healthcheck to pass if running in host network mode
    extra_hosts:
      - 'host.docker.internal:host-gateway'

Any help will be appriciated!
