无法使用Pidgin连接到Google Talk（SASL错误）
在全新安装Ubuntu 11.10后，Pidgin停止连接任何Jabber服务（Google Talk和本地IM）。 奇怪的是，相同的配置适用于使用Ubuntu 11.10的笔记本电脑，但不适用于工作站。 .purple目录已从笔记本电脑复制到工作站，但仍然无效。 运行piding -d > pidgin.log ，会发现以下情况：

如您所见，证书似乎是有效的，问题是：
sasl: sasl_state is -1, failing the mech and trying again
没有启用防火墙，所以必须有其他东西。 有任何想法吗？
由于某种原因， /etc/hosts包含错误的127.0.0.1主机名。 修改后，它开始工作。 希望帮助某人:)
在/ etc / hostname中检查系统的主机名。 然后在/ etc / hosts文件中修改它。 这将解决您的问题:-)
我在Ubuntu 12.04中遇到了同样的问题。 当我看到之前的评论时，我检查了/etc/hosts ，它是空白的。 所以，我添加了以下内容：
127.0.0.1 localhost 127.0.1.1 ubuntu
这就是现在的样子：
root@ubuntu:/etc/apt/apt.conf.d# cat /etc/hosts 127.0.0.1 localhost 127.0.1.1 ubuntu
然后
root@ubuntu:/etc/apt/apt.conf.d# /etc/init.d/networking restart * Running /etc/init.d/networking restart is deprecated because it may not enable again some interfaces * Reconfiguring network interfaces...
退出Pidgin并再次打开它。 瞧它现在就像魅力一样。 希望它也能帮助别人。
我遇到过同样的问题。 事实certificate我已在我的Google帐户上启用了两步validation。 我只是去了我的应用程序专用密码设置（在Google中）并撤销了对Pidgin的访问权限。 然后我添加了Pidgin并生成了一个新的应用程序专用密码，将其输入Pidgin中的我的Google Talk帐户设置，现在一切正常。
