Plex is a local-first media server. See https://www.plex.tv for more information.


  1. Create Plex’s apt source:
    echo deb https://downloads.plex.tv/repo/deb public main | sudo tee /etc/apt/sources.list.d/plexmediaserver.list
  2. Update apt and install:
    sudo apt update
    sudo apt install plexmediaserver

Migrate Metadata Library

By default, Plex’s metadata library is located at /var/lib/plexmediaserver/Library/Application Support/Plex Media Server/. On systems with a small /var partition, this can be problematic. To relocate the metadata library:

  1. Stop Plex:

    sudo systemctl stop plexmediaserver.service
  2. Create a systemd override:

    sudo systemctl edit plexmediaserver.service

    This creates /etc/systemd/system/plexmediaserver.service.d/override.conf.

  3. Delete the contents of the file with Ctrl+Shift+K.

  4. Add this line, replacing DESTINATION_PATH:

  5. Exit and save.

  6. Move the metadata:

    sudo mv --verbose /var/lib/plexmediaserver/Library/ DESTINATION_PATH
  7. Reload systemd manager configuration to use the new override:

    sudo systemctl daemon-reload
  8. Restart Plex:

    sudo systemctl start plexmediaserver.service


  1. Browse to http://<LOCAL-SERVER-IP>:32400/web/index.html replacing LOCAL-SERVER-IP
  2. Complete setup.
