been running Ubuntu 14 LTS for a long time. I had some RAID issues and decided to update the OS (Ubuntu 18.04 LTS)

upgrade OS, no issues. Plexserver works after upgrade. However., I am trying to upgrade the plexserver now to latest (currently running, with no issues, Version 1.21.2.3943)

sudo apt-get update (no issues)
sudo apt-get upgrade (error message)

Is there an easier fix than to uninstall and install Plex?

Did you try to uninstall Plex and install it again? You won’t lose your data

It’s not asking you to uninstall plex and reinstall it -
It doesn’t like /etc/systemd/system/plexmediaserver.service

Just move that file out of that folder and re-run sudo apt-get upgrade

and if you have custom edit in that file -
it’s also telling you to add those edits the proper way with
sudo systemctl edit plexmediaserver.service

moved /etc/systemd/system/plexmediaserver.service out of /etc/systemd/system/
ran sudo apt-get update
ran sudo apt-get upgrade
got error about: Setting up plexmediaserver (1.21.2.3943-a91458577) ... dpkg: error processing package plexmediaserver (--configure): installed plexmediaserver package post-installation script subprocess returned error exit status 1
again, ran: sudo dpkg -i plexmediaserver_1.21.4.4079-1b7748a7b_amd64.deb
no errors
ran sudo apt-get update
ran sudo apt-get upgrade
no errors
all good
