installed plexmediaserver package post-installation script subprocess returned error exit status 1

Hi everyone,
I'm getting the following error when attempting to install the new version of plexmediaserver:

Setting up plexmediaserver (1.13.9.5456-ecd600442) ...
Failed to enable unit: File plexmediaserver.service: Invalid argument
dpkg: error processing package plexmediaserver (--configure):
installed plexmediaserver package post-installation script subprocess returned error exit status 1
Errors were encountered while processing:
plexmediaserver
E: Sub-process /usr/bin/dpkg returned an error code (1)

I'm not seeing anything in the /var/log/apt.
The only item that may provide a little direction is this in the dpkg.log file:

I've attempted to remove and reinstall the application, run the suggested reconfigure and force installation options from:

I'm running Ubuntu 18 - Linux PlexServer 4.15.0-38-generic #41-Ubuntu SMP Wed Oct 10 10:58:23 UTC 2018 i686 i686 i686 GNU/Linux.

Any thoughts would be appreciated.
