FlexGet installation : Ubuntu 12.04 How To

15 Jan

When I read posts on LifeHacker and Gizmodo sometimes, I figure that everybody else in the world is downloading free TV episodes via BitTorrent, and doing it using RSS feeds and an automated process. That can’t possibly be true, but I figured that if other people do this, I should be able to figure out how, too. It is pretty easy to find RSS feeds for various TV shows. Therfore, I thought it would be relatively simple to write a script to download episodes from each one. I figured that I would have to figure out how to sort out duplicate episodes and different quality types (720p, 1080p, etc.) somehow, too. It didn’t take me too long to find out that an excellent Python program called FlexGet already does all this. Plus, it runs from the command line, which is perfect for a headless server, like my Ubuntu Lucid Lynx box.

I don’t actually endorse doing this, by the way, but I was really curious to learn how it was done. I wanted to share what I learned, in case anyone was struggling with the configuration. Also, I am in the process of playing with ffmpeg to verify downloaded content. You will find sometimes, depending on how reliable your feed is, that FlexGet has the ability to add “fake” torrents to your path/queue.


FlexGet’s web site has an excellent walkthrough that describes how to install it on various operating systems. My instructions in this section are not meant to improve on that guide, but merely to summarize it for an Ubuntu Server install.

FlexGet requires Python 2.6. If you don’t already have that installed on your server, try:

$ sudo apt-get install python2.6 python-setuptools

You have to download FlexGet from their web site. Choose the version for Python 2.6. I prefer to copy the URL and download the file via wget.

$ wget http://download.flexget.com/unstable/FlexGet-1.0r1377-py2.6.egg

After you download FlexGet, install it via Python’s easy_install script. You’ll have to specify the name of the FlexGet file you downloaded.

$ sudo easy_install <downloaded egg>

That’s it! Flexget is now installed in the /usr/local/bin directory.

If you run Transmission like I do, you should also install the the TransmisionRPC plugin.

$ sudo easy_install transmissionrpc


Configuring FlexGet is deceptively simple. The configuration file is written in a format I had heard of, but never encountered before: YAML. YAML is simple and powerful, which means that it can be deceptively complex. You can write a config file that does the same thing in a million different ways. FlexGet’s Cookbook shows you a few examples to get you started. It took me a lot of experimentation to find a config file format that I liked. Here is what I ended up with. It’s probably more complex than it needs to be, but I like the idea of using presets to customize different types of downloads. Note that, in YAML, each level of indentation is two spaces (no tabs are allowed).

$ nano ~/.flexget/config.yml

          timeframe: 8 hours
      - series title 1
      - series title 2
      - series title 3

  host: localhost
  port: 9091
  netrc: /home/mjdescy/.netrc
  removewhendone: true
  addpaused: no
  ratio: 1.00

    rss: http://tv.rss.url/
    preset: tv

    rss: http://tv.rss.url/
    preset: tv

This configuration file sets up a preset called “tv” which tells FlexGet to wait 8 hours before selecting episodes of any of the series listed under the 720p heading. 720p is the default quality setting for FlexGet, and is perfectly adequate for my needs. If FlexGet finds an episode of that quality, it will download it; if it finds episodes above that quality level, at 1080p for example, it will ignore them. If no 720p version exists after the “timeframe” of 8 hours is over, FlexGet will select the entry with the highest quality available. FlexGet won’t download the same episode more than once, unless there is a “proper” or “repack” version—a corrected version of a previously released episode—is available.

At the end of the “tv” preset, the “tranmissionrpc” heading instructs FlexGet to use the transmissionrpc plugin to directly send torrent URLs to transmission-daemon for download. This obviates the need to set a watch directory in transmission-daemon. Note that the “netrc” setting refers to a special username/password file that contains the user name and password required to log into transmission daemon. That file should be in the following format, hidden, in your home directory. Make sure you grant only your account access to read that file (i.e., chmod 600 ~/.netrc).

machine localhost
login username
password password123456789

If you do not run transmission-daemon, you could replace the “transmissionrpc” section with a “download” section, or use another plugin. Check out the flexget Cookbook for more information.

The “feeds” section lists all the TV torrent feeds to look in. I have each feed set to use the “tv” preset that I defined above.

Each RSS feed you list can contain a number of TV series (which is the easiest way to set it up), or just one series (you’ll have to find or build custom feeds for this). Flexget will search all the feeds you list for the series titles listed in the “tv” preset.

This configuration file works very well for me. I hope that it helps you get up and running.


FlexGet can be run manually for debugging purposes (flexget -v), but it should be scheduled to run periodically via cron. Note that there is no need to run FlexGet as root. I run it under my own user account. If you want to operate under the principle of least privilege, you could create a “flexget” account, edit its crontab, and grant that account the permissions it needs to get the job done. For my needs, that isn’t necessary. Therefore, to schedule FlexGet to run every hour, I simply edit my own crontab.

$ crontab -e

Add the following line to the crontab file, and save it.

0,30 * * * * /usr/local/bin/flexget –cron -c /home/mjdescy/.flexget/config.yml > /dev/null 2>&1

This cron job will run FlexGet at the top of every hour and half past the hour. FlexGet will read its options from the configuration file I specified (/home/mjdescy/.flexget/config.yml). I redirect output to /dev/null to prevent cron from sending me emails regarding the command’s output.
