Upgrade to 1.15.2.793-782228f99 breaks plex -- Prevents from Starting

look in /var/lib/plexmediaserver/Library/Application Support

If those files are your username and group, then you need a customization override

  1. Look at the file for anything which looks unique to you.
  2. Delete /etc/systemd/system/plexmediaserver.service.
  3. Create the new override in /etc/systemd/system/plexmediaserver.service.d/override.conf

It looks like this:

# Change Plex default variables
[Service]

User=YourUsernameHere
Group=YourGroupHere
#
# put other changed **Variables**here  (UMask, TMPDIR, etc)
#

  1. Save the file (will be owned by root)
  2. systemctl daemon-reload
  3. systemctl restart plexmediaserver
