Script to Auto Update Plex Media Server on Synology NAS

Goals

Make the echoed messages super clear
Make the version checking logic as smart as possible
Ensure the script fails if there are any errors
Ensure temp files are cleaned up properly
Write bash code as idiomatically as possible
Attempt to find the "Plex Media Server" directory that contains Preferences.xml efficiently
Attempt to support all Synology NAS architectures

Usage

First, SSH into your NAS, save the latest release update-plex.sh script somewhere and set it as executable:

$ ssh you@IP_OF_YOUR_NAS
you@yournas:~$ wget "https://github.com/cowboy/synology-update-plex/releases/latest/download/update-plex.sh"
you@yournas:~$ chmod a+x update-plex.sh

Then, create a Scheduled Task with a User-defined script in the Synology DSM Control Panel:

Ensure the User is root
Ensure the Run command is /path/to/update-plex.sh
Add the --plex-pass option (eg. /path/to/update-plex.sh --plex-pass) if you have Plex Pass and want to enable early access / beta releases

Caveats

Be careful when SSHing into your NAS. I'm not responsible if you break anything!
This script may contain bugs. I'm not responsible if it breaks anything!
This script has been tested on a Synology DS918+ NAS running DSM 7. It should work with other Synology NAS models.
This script assumes Plex was installed manually from https://www.plex.tv/media-server-downloads/.
This script sends "Plex Media Server" notifications as "Package Center" because it's simpler than doing it any other way.

Common Issues

If the script is trying to download the wrong release file for your NAS, please see the comments at the top of the get_arch test suite.
If the script fails with Unable to find "Plex Media Server" directory when --plex-pass is specified, you may need to manually change /volume* in the script to your volume's root path.
If the script fails with error = [289] while installing package, add Plex as a trusted publisher for package installations.
