Since the latest pidgin not available in 9.04 repository you need to setup PPA just like instruction in pidgin website. My instruction here is the same although the command a bit different. This will also solve cannot connect to Yahoo Messenger issue.

• run this command in console to open vim editor :

sudo vim /etc/apt/sources.list.d/pidgin-ppa.list

(if you not familiar with vim use gnome editor with command : sudo gedit /etc/apt/sources.list.d/pidgin-ppa.list)
*since it’s using sudo command you will requested to enter your password to enter root mode)

• Add this line:

deb http://ppa.launchpad.net/pidgin-developers/ppa/ubuntu jaunty main

*I bold the jaunty since it will depends on your ubuntu version (8.10=intrepid, 9.04=jaunty, 9.10=karmic). If you not sure run this command : lsb_release –short –codename

* It will print out your ubuntu release codename

If you’re in Indonesia you can put UGM repository (instead the above line):

deb ftp://repo.ugm.ac.id/ppa.launchpad.net/pidgin-developers/ jaunty main

• Save the file. Since you don’t have the file (/etc/apt/sources.list.d/pidgin-ppa.list) it will create new file when you save it.

• Next you also need to download pidgin public key by executing this command:sudo apt-key adv –recv-keys –keyserver keyserver.ubuntu.com 67265eb522bdd6b1c69e66ed7fb8bee0a1f196a8
• Then open your Synaptic Package Manager and click Reload
• Write ‘pidgin’ in your quick search textbox and see if latest pidgin version is 2.6.x

• Right click on the pidgin and select mark for upgrade and click apply

I hope the explanation is clear enough

Cheers..

If you find that copying from your Windows Vista extremely slow  (50KB/s) from wifi you must try this.

Go to your device manager:
