AttributeError: 'module' object has no attribute 'GSSException'

今天泡泡兄问我，大炮，我的面板启动时候报错，帮我看下撒（其实是我要看的），上报错内容：

1. [root@localhost ~]# /etc/init.d/bt restart
   
2. Stopping Bt-Tasks... done
   
3. Stopping Bt-Panel... done
   
4. Starting Bt-Panel... failed

看我后我觉得是不是泡兄做了哪些不常规的操作导致的呢？结果泡兄否认三连：没有。我没有。我就是没有做其他操作。
好吧，根据经验来看，我决定重新帮泡兄修复下面板，正当我兴高采烈的操作完毕之后，发现。。。。还是报做个错啊！
真丢人！找大佬帮看看，一顿梭哈，paramiko组件问题,重装即可：

1. 
   
2. pip install paramiko==2.0.2

然而，大佬就是大佬，一下子解决了，哈哈哈哈，荡气回肠的笑.jpg
