I've installed Ubuntu and Lubuntu a few times now and some of those times I've had the following problem, which I currently have. When I click a torrent magnet link in Chrome (usually from Pirate bay), instead of opening transmission, the only thing that happens is a new Chrome window opens.

Upon other installations, I've not had this problem; transmission opened just as I'd like.

I've tried using Chrome's extension .torrent to Transmission, but I get the error

unable to contact http ://localhost:9091/transmission/rpc

no response

This should help [How to tell chrome what to do with a magnet link][1] [1]:… – BiggJJ Jun 22 '13 at 21:07

Note: Firefox correctly handles magnet links. – Quinn Culver Jul 13 '13 at 16:14
@BiggJJ I tried following Chan-Ho Suh's solution there, but to no avail. – Quinn Culver Jul 14 '13 at 2:44
What version of Google chrome are you running? I use Google Chrome 28.0.1500.71 and it correctly handles magnet links withot to do nothing. – Radu Rădeanu Jul 14 '13 at 8:59

If you want to use torrent to transmission, you have to allow remote access in transmission under preferences/remote.

If you want to open magnet links in transmission by clicking on them, you need to patch the /usr/bin/xdg-open script, here's mine for reference. The added lines are 311 and 490-493.

Thanks, this is the only solution that worked for me. – Bogdan Vancea Jun 4 '14 at 9:10
That was not exactly the solution I was looking for (I don't like having to patch my OS stuff, even if it's just a silly wrapper script). But it worked perfectly. (I'm on Ubuntu 14.04.2 LTS with Chromium set as my default browser.) – zrajm May 31 at 13:46
can i copy and repaste the whole thing again on lubuntu 14.04 lts. – john Jun 3 at 14:18
@john : I'm on 14.04 too, using the same script, it should work :) (but please make a backup just in case) – tpv Jun 4 at 14:25

You can change the default handler for magnet links by editing the file .local/share/applications/mimeapps.list. Add the association to the two sections in the file like this (leaving other entries in those sections intact):

[Default Applications]

[Added Associations]

Log out and log back in for the change to take effect.

I tried this but I hasn't seemed to work. Still chrome just opens a new browser (or a new tab separate from the others; however you wanna put it). – Quinn Culver Jul 21 '13 at 14:50
There's no transmission.desktop in transmission's source file. Check if you meant transmission-gtk.desktop. – Braiam Jul 21 '13 at 15:26
@Braiam Yes, I tried with and without the -gtk. – Quinn Culver Jul 21 '13 at 16:12

If you have installed transmission-gtk then the solution is easy.

gconftool-2 -s /desktop/gnome/url-handlers/magnet/command '/usr/bin/transmission-gtk %s' --type String
gconftool-2 -s /desktop/gnome/url-handlers/magnet/enabled --type Boolean true

The first one adds transmission-gtk as handler for magnet:// links the second enable it.

Since chrome/ium uses xdg-open this is the best method for setting the handlers. You can replace /usr/bin/transmission-gtk for any client you like. This works for almost all flavors of Ubuntu.

You can test this issuing in the terminal xdg-open "magnet:?xt=urn:btih:f41989f9797a88505f9e258d5e5d1354c3731a99" (downloads Ubuntu 13.04 64-bit)

Other solution is using xdg-mime:

xdg-mime default transmission-gtk.desktop application/x-bittorrent
xdg-mime default transmission-gtk.desktop x-scheme-handler/magnet

In case you don't have the mime-types installed use xdg-mime install x-scheme-handler/magnet.

This doesn't seem to have worked. Still, even when I try your test from the terminal (to download Ubuntu), it opens a new Chrome window. – Quinn Culver Jul 21 '13 at 16:06
@QuinnCulver What's the output of gconftool-2 -g /desktop/gnome/url-handlers/magnet/command? – Braiam Jul 21 '13 at 16:50
The output is: /usr/bin/transmission-gtk %s – Quinn Culver Jul 21 '13 at 17:00
@QuinnCulver and gconftool-2 -g /desktop/gnome/url-handlers/magnet/enabled? Try logging out to force the values to be updated. – Braiam Jul 21 '13 at 17:10
The output is: true. I'd rebooted last time I tried your suggested commands. I'll try again; this time I'll only log out. – Quinn Culver Jul 21 '13 at 17:23

To fix this

  1. Install transmission-remote
    sudo apt-get install transmission-remote

  2. Start transmission (transmission-gtk) before adding .torrent files

  3. Enable web client, set port to 9091 (From edit -> preference -> web ) if necessary

I tried this. It didn't seem to work. – Quinn Culver Jul 21 '13 at 16:11

if ur using bittorrent go to preferences-general-click on the tab that says associate with it will work when you try magnet link..

share|improve this answer
You actually have to add the bittorrent entry to the xdg-open list to make this work with chrome as far as I know. Also bittorrent is a name for the system so almost all bittorrent clients have the word bittorrent in it's name. – Arno van der Weijden Dec 12 '13 at 7:07

If you want to Open Piratebay magnet link with Transmission Client then on Magnet Link 1 Right Click 2 Copy Link Location Open Transmission File> Open URL

It's Done
