Server Version#: 1.19.1.2630-72c16a276
Player Version#:

After the last Update of my Plex Media Server on Ubuntu 18.04.4 i get this Info via systemctl status plexmediaserver:

● plexmediaserver.service - Plex Media Server
   Loaded: loaded (/lib/systemd/system/plexmediaserver.service; enabled; vendor preset: enabled)

I restarted, i updated and i don’t find anything about those processes (2056, 2054). I’m also not sure if “Start request repeated too quickly” is a problem or not.

Then in the Logs it says that my adress is already in use:

Does that mean i installed the update wrong?
Anybody any Ideas how to fix that?

(Sorry for my bad english and that i’m a bit of a noob here)

thanks for the logs.

It means that something is still listening to Plex’s ports. (32400, 32401)

If it restarts too quickly without stopping gracefully, this will happen.

netstat -an | grep -i 324

Thanks for the reply.
Unfortunately i cannot find out what it is, that is still listening to Plex’s ports. It says only LISTEN

Could a reinstall help?
Any other ideas?

if you do a ps -ef | grep -i plex does it show any plex-related processes?

that explains it, you’ve got Plex installed from the Ubuntu SNAP store.

Nornal systemctl will not work with them.

snap start and snap stop.

Personally, I don’t like SNAP. It’s not widely accepted yet.
I prefer to run Linux apps using the host’s native control (systemctl).

For your case, you will need to uninstall from the Ubuntu store and download from plex.tv & install it.
