求助fedora 10 更新的问题

用命令行YUM UPDATE更新的时候，出现下面问题

yum update
载入插件: refresh-packagekit
设置更新进程
Traceback (most recent call last):
  File "/usr/bin/yum", line 29, in <module>
    yummain.user_main(sys.argv[1:], exit_code=True)
  File "/usr/share/yum-cli/yummain.py", line 229, in user_main
    errcode = main(args)
  File "/usr/share/yum-cli/yummain.py", line 104, in main
    result, resultmsgs = base.doCommands()
  File "/usr/share/yum-cli/cli.py", line 343, in doCommands
    return self.yum_cli_commands[self.basecmd].doCommand(self, self.basecmd, self.extcmds)
  File "/usr/share/yum-cli/yumcommands.py", line 196, in doCommand
    return base.updatePkgs(extcmds)
  File "/usr/share/yum-cli/cli.py", line 595, in updatePkgs
    self.update()
  File "/usr/lib/python2.5/site-packages/yum/__init__.py", line 2542, in update
    updated_pkg = self.rpmdb.searchPkgTuple(old)[0]
IndexError: list index out of range

想问下如何解决。谢谢各位了

更换一个源
还有检测是否有其他的进程冲突
