I have also un-archived the bz2 file and copied the files into the respective
directories. That didn't work either.   Please let me know the workaround.

Do you have json-glib installed on your system?

No I don't have that file installed.   I have just installed it via the synaptic
package manager. I will try it again.

Still no luck.   Keep going.

stopped working for me yesterday.  I think facebook changed their protocal.  

I'm on ubuntu 9.04 jaunty, using the most recent release of the plugin, installed
using the .deb installer.

sudo apt-get install json-glib
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Couldn't find package json-glib

Is there a certain source that I need to enter?

Might be called libjson-glib.

What version of the Facebook plugin are you using?  Are you using one from within 
Ubuntu, or version 1.51 from the website here?

I got it installed and its still not working.

Are you trying to install the pidgin-facebookchat package from within Ubuntu, or 
version 1.51 from the website here?

It doesn't matter which you install it from, it just doesn't work.  Facebook has been
updating like crazy the last few days, and facebook chat isn't working.  Pidgin or
even Digsby's facebook app.  The protocol has changed.

neuster, your issue is seperate.  If you feel that the protocol has changed can you 
open a new issue ticket and paste a debug log of the new protocol.

(No comment was entered for this change.)

Are you for real???   I gave the error code that I received in the original posting. 
I don't know what else you want.

The most recent message I have is 

"I got it installed and its still not working."

I assumed the first post is invalid because you've made progress since then.

What progress????   I still get the same message.   That is not progress!!!

lturkin:

1) Are you installing the Facebook plugin from this website or through apt-get?

2) Please run pidgin from a terminal using "pidgin --debug" then post the output 
here.

I too am having problems getting the Facebook plugin to work on Ubuntu 9.0.4.  Note
that this is a brandspanking new installation.  Appreciate any help that anyone can
provide.

Here's a debug dump:

Thanks...Bob

I'm also having trouble installing. Not sure if it's related to this issue or not,
but when I try to install via package installer I get the error "Dependency is not
satisfiable: libjson-glib-1.0.0" In spite of the fact that I have repeatedly verified
that it is installed'

	
I can not install on Hardy Heron, I do not have the package libjson-glib-1.0-0 

Here! libjson-glib-1.0-0 


http://repository.maemo.org/extras-devel/pool/diablo/free/j/json-glib/

For Hardy, you can download the library from the Intrepid library.  See here:
http://www.dedyisn.net/2009/06/install-facebook-plugin-in-pidgin-on-ubuntu-hardy-804/

Interestingly, I had to uninstall my local build of Pidgin 2.5.8 before the facebook
plugin would load.

Thanks you! pkobayashi

i was getting the json glib error, then ran:

sudo apt-get -f install
sudo apt-get autoremove

and afterwards 

sudo apt-get install pidgin-facebookchat

worked ok

Hi. I'm using ubuntu 9.04, and I can't get pidgin facebook chat to work. 
facebook chat tries to login to facebook (I even get to see who's online for an
instant), but disconnects immediately saying "chat service currently unavailable". 

All that is using pidgin and pidgin-facebook-chat from the ubuntu repos. 

Also, when I try to install pidgin facebook chat from the deb package, I get the
error "Dependency is not satisfiable: libjson-glib-1.0-0 (>= 0.7.6)". Installing
libjson-glib-1.0.0 from synaptic doesn't seem to work. The same error keeps appearing. 
Does anyone know what's wrong?

<<Does anyone know what's wrong?>>

Well that's simple, you have to read carefully what synaptic shows. Last version from
ubuntu jaunty repositories is libjson-glib-1.0-0 (0.6.2-3) clearly older than (0.7.6)

Seems like ubuntu 9.10 (karmic koala) is shipping pidgin-facebookchat 1.6 and
json-glib 0.7.6 so you just have to wait roughly a month to get it working

"pidgin-facebookchat" source package in Ubuntu ->
https://launchpad.net/ubuntu/+source/pidgin-facebookchat
"json-glib" source package in Ubuntu -> https://launchpad.net/ubuntu/+source/json-glib

I think this is not a bug/defect but rather a misconfiguration 

> oWhat is the problem?

Clearly is a problem with the configuration of GNOME/Ubuntu and not an issue with the 
.deb-file of pidgin-facebootchat. Also, installation on older systems like Hardy 
where some of the additional libs are missing shouldn't be discussed here because 
it's a bug report and not a support forum, is it?

Suggestion: Close this report.

I got it to work by installing libjson-glib form the karmic repository. You can get
it here http://packages.ubuntu.com/karmic/i386/libjson-glib-1.0-0/download

You could also just install pidgin-facebook from the repos.

Sometimes, when you select "Open" when downloading a .deb, you get that helper error.
Solution: Tell your browser to download it, not just open it.

known working on ubuntu netbook remix under 2.6.28-15 kernel (jaunty).

DO NOT DOWNLOAD FROM GOOGLE CODE (i.e. this page) get it from the repository this way:
* make sure you've exited from pidgin
* open a terminal window
* type sudo apt-get clean && apt-get update
* hit enter
* type sudo apt-get install pidgin-facebookchat
* hit enter
* launch pidgin
* add it as you would any other account
* enjoy

hope that helps!

This combination worked for me also well on Squeeze:

I am attempting to get this working on Fedora 11.
Pidgin was installed from source and is at the latest release as of today. All working.

I had the json library installed from the Fedora repo, but it was below the required
0.7.6 version. So I installed the most recent version (0.8.0 I think) of json-glib
from source. Seemed to go OK.

I do not have facebook chat as an option in accounts, and I get the same ELF class
error in the debug window of Pidgin when it tries to intialise the plugin.

Anyone have any suggestions for this ? There are some of us out here that don't run
Ubuntu :)

Not an issue for Koala. The problem is a distro thing. Many distros (especially
ubuntu) like to hold back updating certain libraries until the next major version
release of that distro (i remember wishing i could have audacious2 and having to get
it from a 3rd party repos until i finally got koala).

I experienced the same issue after installing pidgin-facebookchat-1.61.deb on ubuntu
9.04..
I finally fixed it after installing 1.62
deleting the facebook account in pidgin..
then re-adding the account.

Works perfectly once again.

Nothing to do!
I have spent several days to fix the libjson-glib-1.0-0 issue and I have lost all the
wishes. How Have I do?

If I update the plugin using the deb file I get the common error:  libjson-glib-1.0-0
(>= 0.7.6)

thanks
