yum 安装管理器在 centos 6.6 中不起作用

Question

我在 centos 6.6 中遇到 yum 安装管理器的问题

root@mmopuru:~ # cat /etc/*release
CentOS release 6.6 (Final)
CentOS release 6.6 (Final)
CentOS release 6.6 (Final)

root@mmopuru:~ # uname -a
Linux mmopuru.puppetlabs.vm 2.6.32-504.el6.i686 #1 SMP Wed Oct 15 03:02:07 UTC 2014 i686 i686 i386 GNU/Linux

它抛出以下错误。我都试过了，但没用。

root@mmopuru:~ # yum install python-pip
Loaded plugins: fastestmirror, security
Setting up Install Process
Repository 'updates' is missing name in configuration, using id
Loading mirror speeds from cached hostfile

Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: addons. Please verify its path and try again

如何解决？

当我运行 yum repolist

# This file uses a new mirrorlist system developed by Lance Davis for CentOS.
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

Answer 1

删除“插件”存储库定义，该定义在 CentOS 6 中不存在（它仅在 CentOS 5 中存在，但为空）。

Answer 2

我刚刚回答了similar question，即同样的错误，但对于 EPEL 回购。我在这里回答，可能对一些未来的 SO 用户有帮助。

解决方案：快速解决方法是更新您的 SSL 证书：

yum -y upgrade ca-certificates

证书更新时也可能出现上述错误，如果是这样，只需禁用导致错误的 repo 即addons，请使用以下命令：

yum -y upgrade ca-certificates --disablerepo=addons

如果您在不同的 repo 中遇到同样的错误，只需将它的名称放在 --disablerepo=<repo-name> 标志上。

注意：如果您不是root 用户，请使用sudo。
