在系统自动更新的时候出现了
an internal system error has occurred 信息
下面是具体的信息
Error Type: <type 'exceptions.IndexError'>
Error Value: list index out of range
  File : /usr/share/PackageKit/helpers/yum/yumBackend.py, line 2202, in <module>
    main()
  File : /usr/share/PackageKit/helpers/yum/yumBackend.py, line 2199, in main
    backend.dispatcher(sys.argv[1:])
  File : /usr/lib/python2.5/site-packages/packagekit/backend.py, line 599, in dispatcher
    self.dispatch_command(args[0], args[1:])
  File : /usr/lib/python2.5/site-packages/packagekit/backend.py, line 577, in dispatch_command
    self.update_system()
  File : /usr/share/PackageKit/helpers/yum/yumBackend.py, line 1099, in update_system
    txmbr = self.yumbase.update() # Add all updates to Transaction
  File : /usr/lib/python2.5/site-packages/yum/__init__.py, line 2542, in update
    updated_pkg = self.rpmdb.searchPkgTuple(old)[0]

删除了更新的缓存也是一样的
