Yum 中断,现在出现冲突

Yum 中断,现在出现冲突

我有一台 Centos 6.7 服务器,我想更新它。所以我做了

yum update

但是,这是在实时服务器上进行的(我知道我不太聪明)。服务器资源耗尽,yum 更新中断。我现在无法再运行yum update。我试过了yum clean all,但似乎无法启动 yum。

这是我得到的:

# yum update
Loaded plugins: downloadonly, fastestmirror
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 300, in user_main
    errcode = main(args)
  File "/usr/share/yum-cli/yummain.py", line 115, in main
    base.getOptionsConfig(args)
  File "/usr/share/yum-cli/cli.py", line 229, in getOptionsConfig
    self.conf

  File "/usr/lib/python2.6/site-packages/yum/__init__.py", line 335, in _getConfig

    func(conduitcls(self, self.base, conf, **kwargs))

  File "/usr/lib64/python2.6/optparse.py", line 1020, in add_option
    self._check_conflict(option)
  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,但我不确定如何修复它。

答案1

昨天我也被要求查看一个执行此操作的系统。在我的系统中安装了 2 个版本的 yum

yum-3.2.29-60.el6.centos.noarch
yum-3.2.29-69.el6.centos.noarch

但删除较新的版本(rpm -e)并没有解决问题。我还必须删除yum-plugin-downloadonly-1.1.30-30.el6.noarch它及其依赖包yum-cron-3.2.29-69.el6.centos.noarch

完成后我就可以再次运行 yum 并运行yum-complete-transaction

答案2

尝试在暂时禁用downloadonly插件的同时进行更新,使用以下命令:

yum update --disableplugin=downloadonly

答案3

我可以通过运行以下命令解决这个问题:

yum install yum-utils 
yum-complete-transaction
