Updating Plex Media Server on Ubuntu Server

First of all, download the appropriate file for your operating system, https://plex.tv/downloads. For me I am using 64-bit.

In a command line I type:

wget https://downloads.plex.tv/plex-media-server/0.9.12.1.1079-b655370/plexmediaserver_0.9.12.1.1079-b655370_amd64.deb

This downloads the file to my server, from here I simply install the software:

sudo dpkg -i plexmediaserver_0.9.12.1.1079-b655370_amd64.deb

Once the install is finished, reboot.

sudo reboot
