Do you miss good old Yahoo Messenger! from Windows in Ubuntu? Then here is a solution for you...

GYachI is a software which gives you all the features of Yahoo Messenger !... really...

Installing GYachI

The instructions can be found at https://launchpad.net/~loell/+archive/ppa

Add these 2 lines in sources.list (normally /etc/apt/sources.list)

deb http://ppa.launchpad.net/loell/ppa/ubuntu gutsy main
deb-src http://ppa.launchpad.net/loell/ppa/ubuntu gutsy main

Change gutsy to your distribution (jaunty, intrepid, hardy...)

Run the command...

sudo apt-get install gyachi

That's it... it is a full fledged Yahoo Messenger frontend :)

Troubleshooting

If while logging in it shows error like "Invalid Username or Incorrect Password", and you are sure you entered them correctly, then it is the problem with special characters in your password. Change the password and you are good to go...

Also, use the Protocol "YMSG-15 / Messenger 8" as the older Protocols are being turned off...

One more trouble, I was logged in, I could send messages, but my friends were not able to get those messages !!! Yeah, I only noticed after 2 days of utter silence... Change the Server to "cn.scs.msg.yahoo.com". That does the trick... :)
