yum update

然而,这是在一个真实的服务器上(我不是很聪明,我知道).服务器资源耗尽,yum更新中断.我现在不能再运行yum update了.我已经尝试了所有的yum清洁,但似乎无法开始百胜.

这就是我得到的：

# yum update
Loaded plugins: downloadonly,fastestmirror
Traceback (most recent call last):

    yummain.user_main(sys.argv[1:],exit_code=True)

  File "/usr/lib64/python2.6/optparse.py",line 995,in _check_conflict
    option)
optparse.OptionConflictError: option --downloadonly: conflicting option string(s): --downloadonly

Python似乎有一个错误,但我不确定如何解决它.
