Upgrade of plex media server fails

[scouseboy99]

Server Version#: 1.13.9.5456
Player Version#: 3.69.1

Hi All,

I am trying to update my media server to the lastest version. However I keep getting an error and the update exits.

The following is the output from the console
(Reading database … 135372 files and directories currently installed.)
Preparing to unpack plexmediaserver_1.19.3.2764-ef515a800_amd64.deb …

I have spent many hours Googling and combing the forum for a solution. Could someone please point me in the direction of a procedure to correct the error and allow the upgrade to proceed.

My server is currently running Ubuntu 16.04. I can do a release upgrade to 20.04 but I am not sure that this will only compound the issue. I am very confident with the file system and working with consoles.

Thanks is anticipation

i had the same problem, i solved it by renaming the file /etc/systemd/system/plexmediaserver.service

mv /etc/systemd/system/plexmediaserver.service /etc/systemd/system/plexmediaserver.service.old

and i re ran the installation

dpkg -i plexmediaserver_1.19.3.2764-ef515a800_amd64.deb

i’ve got a warning :
Warning: The unit file, source configuration file or drop-ins of plexmediaserver.service changed on disk. Run ‘systemctl daemon-reload’ to reload units.

but the installation continue and after it is installed i saw the last version in my plex setting on web broswer.

Please be advised:

1. /etc/systemd/system/plexmediaserver.service is leftover from a Ubuntu BUG. from 2016 (Ubuntu 16.04)
2. The file does not belong there.
3. The proper location, which I install , is located in /lib/systemd/system/plexmediaserver.service
4. The installation script fails because I am not permitting full service override definitions in /etc
5. Proper use of /etc/systemd/system/plexmedisserver.service.d/override.conf, which allows customizing of username, file locations, and some environment variables.

I am willing to help overcome this transition.

Thank you both for your offer of assistance. Took the plunge and did a re-install of the Linux OS. Then re-installed plex from scratch. All went well and one re-attached my library that is held on an LVM volume, the system is back up and running and working well.

Once again thanks
