title: Yum crashed with Keyboard Interrupt error
body: <p>I installed the newer version of python (3.2.3) than the one available in Fedora16 (python2.7)</p>
  
  <p>And now <code>yum</code> stops working. It shows the following error.</p>
  
  <pre><code>[root@localhost yum-3.4.3]# yum
    File "/usr/bin/yum", line 30
     except KeyboardInterrupt, e:
                             ^
  SyntaxError: invalid syntax
  </code></pre>
  
  <p>Please advice as how to resolve the error. It would be helpful as I am not able to update or install any package.</p>
