How to completely remove Plex Media Server?

Source: https://support.plex.tv/hc/en-us/articles/201941078-Uninstall-Plex-Media-Server

1. Shut down Plex Media Server
   

   service plexmediaserver stop

2. Remove the installed package
   

   dpkg -r plexmediaserver

3. Remove the library directory of plex
   

   rm -R /var/lib/plexmediaserver/Library/Application Support/Plex Media Server/

But then, when I wanted to reinstall it, I ran into some errors, and the solution was to make sure that the /var/lib/plexmediaserver folder exists and the plex:plex user/group has owner access to it:

sudo mkdir /var/lib/plexmediaserver
sudo addgroup plex
sudo adduser plex plex
sudo chown plex:plex /var/lib/plexmediaserver

Ubuntu Firewall

UFW (Uncomplicated Firewall) comes with Ubuntu preinstalled, but it is disabled by default:

sudo ufw enable

Then you'll have to allow specific ports for some applications.
For example, to allow the default port of Transmission Bittorrent Client:

sudo ufw allow 51413

Another way to allow ports for an application is to create an application profile and allow that profile.
For example to allow Plex Media Server:

1. Edit (create) the app profile:
   

   sudo gedit /etc/ufw/applications.d/PlexMediaServer

2. Paste the following in it:
   

   [PlexMediaServer]
   title=Plex Media Server
   description=This opens up PlexMediaServer for http (32400), upnp, and autodiscovery.
   ports=32469/tcp|32413/udp|1900/udp|32400/tcp|32412/udp|32410/udp|32414/udp

3. Allow the profile:
   

   ufw allow PlexMediaServer

Refer to Ubuntu Wiki and Ubuntu Help for more information about UFW.
The solution for Plex Media Server profile was originally posted on Plex Forum.

Some other useful commands:
List all rules (with reference number):

sudo ufw status numbered

Then the reference numbers can be used to delete a rule:

sudo ufw delete 1

The other way to delete a rule would be like this (for an allow rule):

sudo ufw delete allow 51413

Building a Plex Plugin from scratch

This post was moved to my other blog: Alice@Development

Plex Plugin Installer

So, since I found plex plugin manual installation painfully boring, I wrote a nautilus script to do the job for me.
Instead of copy-pasting, you can also download this script form github.

I wasted a couple hours finding out that  if I use "double quotes" instead of 'single quotes' when assigning the plugin folder path to the PLUGIN_FOLDER variable, then 1.) the path will break on spaces and won't work; 2.) if I surround the call with '"'-s (a double quote between two single quotes) or just another "-s the program will fail not finding the files/directories. This was the tricky part because if instead of running I echoed the lines, they looked perfectly okay, and if I copy-pasted them to the command line they would even run properly... only not within a script.

#!/bin/bash
# nautilus script
# install PLEX plugin on Ubuntu 12.04.

# run this script by right clicking on the directory you want to install
install_plugin () {
 # standard feature: install by copying folder
 # future enhancement: install from ZIP file

 PARAMETERS=( "$@" )               ## array containing all params passed to the script

 PLUGIN_FOLDER='/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-ins/'

 # read folder paths into TO_BE_INSTALLED
 IFS=$'\n' read -d '' -r -a TO_BE_INSTALLED < <(printf '%s\n' $PARAMETERS); unset $IFS

 need_to_restart_server=false

 for package in "${TO_BE_INSTALLED[@]}"; do
  package_name="${package##*/}" # Strip longest match of substring (*/) from front of string

 # sanity check: is the path correct? it should be a directory and end with ".bundle".
  if  [[ -d "$package" ]]; then # if selected path IS a directory
   if [[ "${package_name##*.}" == "bundle" ]]; then
    installed_package=$PLUGIN_FOLDER$package_name
   # check if plugin already exists
    if [[ -d "$installed_package" ]]; then 
     # if yes, ask to delete it 
     echo -n "A package with the same name is already installed. Would you like to overwrite it? (yes/no): "; read overwrite 
     if [[ $overwrite == [Yy][Ee][Ss] || $overwrite == [Yy] ]]; then 
      sudo rm -R "$installed_package"
     else
      echo "You chose not to overwrite $package_name so it will not be processed."
      continue
     fi
    fi
   # install plugin
    #copy the downloaded plugin to the plex plug-in directory
    sudo cp -R "$package" "$PLUGIN_FOLDER"

    #change the permissions to be like the existing plug-ins 
    #(this is not needed in 14.04 anymore)
    sudo chmod ugoa+rx "$installed_package"

    #change the owner of the files to be like the existing plug-ins
    sudo chown -R plex:plex "$installed_package"

    need_to_restart_server=true

   else # if not "bundle"
    echo "Package name should end with '.bundle'. $package_name will not be processed."
    continue # process next package instead
   fi

  else # if not directory
   echo "Package should be a directory. $package_name will not be processed."
   continue # process next package instead
  fi

 done
# when finished with all packages, restart plex server.
if [[ $need_to_restart_server = true ]]; then 
 sudo service plexmediaserver stop
 sleep 5
 sudo service plexmediaserver start
 
 echo "Installation complete. Your new plug-in should show up now in PLEX."
fi
}

export -f install_plugin

gnome-terminal --execute bash -c 'install_plugin "$NAUTILUS_SCRIPT_SELECTED_FILE_PATHS"; bash'

Plex Configuration for various reasons

Restart Plex Server:

~$ sudo service plexmediaserver stop

~$ sudo service plexmediaserver start

Install Plug-in manually:

UPDATE: a script for plugin installation can be found here.

Plug-in directory: /var/lib/plexmediaserver/Library/Application\ Support/Plex\ Media\ Server/Plug-ins/

To install a new plug-in:

the new plug-in's directory name should end with ".bundle" like the existing plug-in directories.

copy the downloaded plugin to the plex plug-in directory

~$ sudo cp -R /download_dir/new_plug-in_dir /plex_plugin_dir/

change the permissions to be like the existing plug-ins (this is not needed in 14.04 anymore)

~$ sudo chmod ugoa+rx /plex_plugin_dir/new_plug-in_dir

change the owner of the files to be like the existing plug-ins

~$ sudo chown -R plex:plex /plex_plugin_dir/new_plug-in_dir

restart plex server as written above.

the new plug-in should show up in plex.

rawrAnime: https://forums.plex.tv/index.php/topic/103120-rel-rawranime-watch-hd-subbed-and-dubbed-anime/

works fine for me.

AnimeToon.tv https://forums.plex.tv/index.php/topic/101657-rel-animetoontv-watch-cartoons-and-english-dubbed-anime/

To get AnimeToon working you need to update this file:
AnimeToon.bundle/Contents/Services/URL/AnimeToon/ServiceCode.pys

UPDATE: a fixed version of the plugin can be downloaded from here.

Add these lines to the end of the file:
