The latest version of Pidgin, 2.7.*, is experiencing some difficulty connecting to Gtalk.
The reason for this was a change in the libs used. Prior to version 2.6 .* the SASL (Simple Autentication and Security Layer) libs were not used by Pidgin to connect to Gtalk.
Outcome: Older versions of Pidgin easily connect to Gtalk, while newer versions can not.
How to fix it ???
1. type in the terminal: sudo apt-get install-y – force-yes cyrus-sasl libsasl2-plug-*
2. The following libs should be installed: cyrus-sasl, libsasl2, libsasl2-plug-plain (needed to be able to connect to Gtalk network)
3. Now set up the account:
Accounts > Add or Modify > xmpp or googletalk
User Name: your Gmail username without the @
Password: your password
click Advanced Tab:
- Require SSL/TLS
- Force old (port 5223) SSL
[ ] Allow plaintext auth over unencrypted streams
Connect port: 443

Click save and you have from now on google-talk IM.
