故障现象：

很久操作系统没有升级了，今天更新提示操作系统升级失败，原因是下载源数据错误，认为与Redhat被IBM收购之后, 收紧大家白嫖的资源有关系, 见下图。操作系统为:CentOS Stream 9

# dnf update

解决方案

1、源配置yum配置文件路径 /etc/yum.repos.d/centos.repo 2、备份源配置 [很重要，如果不行方便恢复]

[root@server yum.repos.d]# cp centos-addons.repo /etc/yum.repos.d/centos-addons.repo.bak

! 3、通过查看发现原配置为 CentOS 官方源

[root@server yum.repos.d]# cat centos-addons.repo

4、编辑源文件 4.1）使用:%d命令 :%d命令可以删除整个文件的内容。只需在命令模式下输入:%d即可。这将删除所有行，包括最后一行。 4.2）

# CentOS-Base.repo
#
# 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.
