How to: Plex Media Server on Ubuntu
I thought I could write a quick HOW TO for installing PMS (Plex Media Server) on Ubuntu, because many other linux guides on the internet helped me very much previously.
NOTE: If you use the Ubuntu Desktop version consider using this guide.
I used Ubuntu Server 12.04 LTS, but it should work on older Ubuntu versions, too.
First, you have to open a terminal window or ssh into your computer.
Step 1: Install Avahi
Avahi is needed for advertising Plex services. It's like Apple's Bonjour.
It is enough to copy&paste this line to install Avahi:
sudo apt-get install avahi-daemon
However you can do much more with Avahi. For example advertising AFP-Shares. This guide covers it.
Step 2: Install Plex
sudo nano /etc/apt/sources.list
Then add "deb http://www.plexapp.com/repo lucid main" to the file.
Or add "deb http://www.plexapp.com/repo beta main" for the BETA versions.
You can put it wherever you like.
Use something like ctrl+x (mac-keyboard) or Strg+x (Windows-keyboard) to close and safe the file.
sudo apt-get update
sudo apt-get install plexmediaserver
Access Plex through a browser on the computer running PMS
or any other computer (connected via LAN)
To initially add media to your library, you can click on one of those icons on your PMS website. For example Movies:
Then you can choose a name and directory:
The scanning will take a while, depending on how many movies or tv-shows you have.
You should see the progress on the web client
(optional) Read this if Plex doesn't play any files:
If Plex doesn't play any files, make sure your permissions are right. Because Plex is a new User it may not have the permissions to play your media.
You can try it the easy way: Add the Plex-User to your Group:
gpasswd -a plex myuser
Or if you want to change the permissions properly (more work):
cd into your media directory, for example:
Then look up the permissions with
Here you can see if your directory has read/write/execute for every user. Its like this: (NO COLOURS in real life)
drwxrwxr-x 365 USER GROUP ---somemorestuff-- FOLDERNAME
rwx indicates read/write/execute for the USER.
rwx indicates read/write/execute for the GROUP
r-x indicates that every other user has read/-/execute access.
I would assume the User Plex only has as much access as the last three letters/hyphens (every other user).
It works for me like this so the blue bit should look different in your setup.
The easyiest thing you can do here is put the plex user in the group:
sudo chown YOURUSER:plex -R /home/user/MEDIADIRECTORY
This way plex will be the group and have the groups' permissions (green rwx). BUT if there is no rwx, you will have to give it read/write/execute permissions:
sudo chmod 770 -R /home/user/MEDIADIRECTORY
The first 7 gives the user read/write/execute permissions. The second 7 is for the group. The 0 in this case gives every other user no permissions at all.
The -R will change the permissions of all files in the folder.
Now it should look like this: (check with ls -l again!)
rwxrwx--- 365 USER plex ---somemorestuff-- FOLDERNAME
Please note: This is just an option!
A complete Linux permissions guide would be too long for this How To. But you can find plenty good Youtube videos on this topic

Update Plex: (You should do that every now and then)
Plex updates just like most of the other Linux programs. With aptitude:
(Every other programm will update too)
sudo aptitude update && sudo aptitude safe-upgrade
All programs mentioned here will be updated.
Then you have to type in Y to continue.
(optional) Migrate library from 0.9.2.x
