Synology makes it super easy to install Plex Media Server on its DiskStation NAS boxes, but missing from the simple user interface is a way to update Plex Media Server if a new version releases. Don’t worry, though—there’s still a way to do it.
UPDATE: Synology has now added the ability to update Plex Media Server right from within Package Center just like any other package, but the below method still works if you ever want to push a manual update.
You can set many of Synology’s packages available from the Package Center in DiskStation Manager to be auto-updated if you want them to be. Otherwise, you’re notified when packages are available for updating. The trouble is that Plex Media Server is left out, meaning you have to update it manually. Here’s how to do it.
Start by firing up your Plex server’s user interface, and then click the “Settings” option.
The next screen shows what version of Plex Media Server you’re currently running. If an update is available, it will tell you just to the right of the version number. If there’s an update, click the “please install manually” link to get started.
An .SPK file begins downloading.
When the download is done, fire up DiskStation Manager, and then open Package Center.
In Package Center, click the “Manual Install” button.
Click the “Browse” button.
Select the .SPK file you just downloaded, and then hit the “Open” button.
And then click the “Next” button to start the update.
You may get a pop-up that says “This package is published by an unknown publisher. Are you sure you want to continue?” Go ahead and hit the “Yes” button.
Click “Apply” on the next screen.
Give it a few moments to install the update. When it’s complete, the installation window automatically closes and you’re back at your list of installed packages. There, you’ll see that Plex is now running the latest version.
It’s a little cumbersome, and better automation would be nice. But, at least it’s not too difficult a process.
