问题描述

Errors during downloading metadata for repository ‘appstream’:

  • Status code: 404 for http://mirror.centos/centos/8/AppStream/x86_64/os/repodata/repomd.xml (IP: 111.90.139.139)

解决方案

使用阿里云或其他第三方镜像源来替代默认的 CentOS 镜像。阿里云提供了稳定的 CentOS 镜像。

修改 CentOS-Linux-BaseOS.repo 和 CentOS-Linux-AppStream.repo 中的 baseurl 为阿里云的镜像地址:

sudo vi /etc/yum.repos.d/CentOS-Linux-BaseOS.repo

更改为:

[baseos]
name=CentOS-8 - BaseOS
baseurl=http://mirrors.aliyun/centos/8/BaseOS/x86_64/os/
enabled=1
gpgcheck=1
gpgkey=https://mirrors.aliyun/centos/RPM-GPG-KEY-CentOS-8

对于 CentOS-Linux-AppStream.repo 也是类似的修改:

sudo vi /etc/yum.repos.d/CentOS-Linux-AppStream.repo

更改为:

[appstream]
name=CentOS-8 - AppStream
baseurl=http://mirrors.aliyun/centos/8/AppStream/x86_64/os/
enabled=1
gpgcheck=1
gpgkey=https://mirrors.aliyun/centos/RPM-GPG-KEY-CentOS-8

保存并退出。

清理 yum 缓存并更新:

yum clean all
yum update
