Plex server won't start after server update

Server Version#: Ubuntu 18.04.1 LTS
Player Version#: 1.13.6.5339

I just upgraded my server and rebooted and when it turned back on plex would no longer start.

This is the error I get:

● plexmediaserver.service - Plex Media Server for Linux

 Main PID: 3813 (code=exited, status=255)

I have tried reinstalling the latest update of plex. Cannot find anything else on the forums.

Thanks in advanced.

I have the same trouble, the last 2 updates of plex media server don’t work, once they are installed my servers just disapear from the plex web app, they are not even showing up, i rolled back the plex update.

That is just a status report.

Let’s see what the errors are:

sudo journalctl -xe | grep -i plex`

Read through it. You see see it paginated by date/time.
When you find the problem, it will be obvious (Permission denied / not found / etc )

Thanks for you reply.

In the end I purged plex and re installed it.

Seemed to fix the issue.

Thermonuclear is always an option! :smiley:

Just updated to the newest version of plex that got released (1.13.7.5369) and it will not start again:

I have an old Mac Mini that I have been running Plex on. It is so old that it can’t upgrade the OS beyond 10.8. The version I was running was 1.3.4. I just told Plex to upgrade itself and now it won’t start. The message I get is that the version I have requires OS 10.9 or later. Now I am screwed cause I don’t know how to load an older version of Plex and there is nobody to contact. IDEAS???

Ideally using a more recent version of the OS is best at some point even using a older version might not work fully, not to mention you might be exposed to security issues. Still u might try to look in Library/Application Support/Plex Media Server/Updates and see if the previous version is still there, if so you’d need to install it manually.

Do you have any ideas how I could fix my Plex server?

You should be able to get more info on why it’s not starting using the command @ChuckPa suggested earlier:

sudo journalctl -xe | grep -i plex

I ran the command and this is the output:

Please back down to 1.13.6 and retest.

If successful, we have the issue contained to 1.13.7 and can then continue by invoking a manual, command-line start.

Thank you. Earlier updates are there. It isn’t clear how to manually install though. I find a file called “updater” but it is a unix executable file and I double click on it and nothing seems to happen. Help.

What is troubling here is I am used to apple programs checking to see if they will work before installing. I usually do every update I can because of security issues but when I did this it made my computer unusable, at least for this purpose, as that is the main use for this computer.

Anyhow, looks like i can fix it but I will need more help.

Thanks for the reply.

Where can I get the download from?

Instead of 1.13.6, if you don’t have it, is to use current public 1.13.5 from plex.tv/downloads

As for starting PMS at the command line, I did not say to “Click on it” (graphical). I specifically stated “command-line start” in a terminal session.

Hi, I appear to be having the same issue with 1.13.5 (public) on an Odroid XU4 with Armbian Bionic (Ubuntu 18.04) freshly installed.

UPDATE: This behavior is only apparent under Ubuntu. The same version of Plex works under Armbian Stretch (Debian)…

My issue is similar, my Mac is running fine and my server is accessible through my Samsung hub (smartTV), browsers and Roku app. What I can’t do is access is through the app on my tablet. This tablet is a brand new device (Samsung Tab A 2017), running Android 7.1.1 and when it installed the latest Plex version (7.2.6.7169), it isnt playing nice and won’t allow me to access my main media library. I’m running Mac OS 10.8 and I really can’t update it any further. Where can I find a previous version of Plex for my tablet?
