如何修复 Centos 5 上的 yum install not valid release 错误

当我尝试 yum 安装任何东西时，我得到：

-bash-3.2# yum install strace
Loading "fastestmirror" plugin

 * dag: apt.sw.be
 * lxlabsupdate: download.lxlabs.com
 * rpmforge: fr2.rpmfind.net

YumRepo Warning: not using ftp, http[s], or file for repos, skipping - 5.2 is not a valid release or hasnt been released yet
removing mirrorlist with no valid mirrors: //var/cache/yum/base/mirrorlist.txt
Error: Cannot find a valid baseurl for repo: base

在 /etc/yum.repos.d 中我有文件：

CentOS-Base.repo         CentOS-Media.repo  mirrors-rpmforge
CentOS-Base.repo.rpmnew  lxlabs.repo        rpmforge.repo

CentOS-Base.repo：

# CentOS-Base.repo
#
# 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.

如何修复？

答案1

在您的 .repo 文件中更改?release=5.2为。?release=5

答案2

mirrorlist您的 CentOS-Base.repo 文件中属性中的 URL/etc/yum.repos.d/定义错误。它将发布版本号硬编码为5.2代替5。我建议不要对版本号进行硬编码，而是在 URL 中使用系统提供的变量，如 baseurl 条目中所示。

因此，您希望每个条目都使用类似这样的内容（保留现有repo=值）：

镜像列表=http://mirrorlist.centos.org/?release=5.2&arch=$basearch&repo=os

答案3

将完整的发行版本号（例如“5”）添加到文件“/etc/yum/vars/releasever”。您可能还需要创建目录“/etc/yum/vars/”。这样做可以避免直接编辑任何 repo 文件，并且您的自定义值在软件包和操作系统升级后仍然有效；只需记住适当更改该值（如果您升级到新的操作系统版本等）。
