Error updating PMS on Raspberry Pi 4, Debian Buster

Plex Media Server Desktops & Laptops

Server wont update to newest version. When attempting to do so via the CLI/SSH, I get the error quoted below. I am hoping to not have to reinstall the server as I have a rather large library which was extensively customized with metadata and have had to do so several times already.

It is specifically pointing out the problem.

PlexMediaServer install: File “/etc/systemd/system/plexmediaserver.service”

On Systemd systems,

  1. The main service is in /lib/systemd/system/plexmediaserver.service
  2. Customizations belong in /etc/systemd/system/plexmediaserver.service.d/override.conf

Right on. Thanks for the breakdown, as I am new-ish to this. Which files/changes in existing files must I move in order to rectify the problem?

Seems like im having the same error after latest update on Raspberry Pi 4, Debian Buster. even with sudo purging the plexmedia server and trying to do the complete reinstall It gives me the very same error.

Precisely when my error started to occur

Having this error as well and I don’t understand how to fix it.

I found a temporary fix to maintain my library/functional server settings and still allow other packages to update as normal by putting the package “plexmediaserver” on hold.

sudo apt-mark hold plexmediaserver

when a fix is found and Plex can be updated again, use

sudo apt-mark unhold plexmediaserver

Again, really just a temporary fix until the error can be corrected as all it does is prevent the plexmediaserver package from fouling the update process of other packages
