篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Centos8 yum 报错 Error: Failed to download metadata for repo 'appstream': Cannot prepare inter相关的知识,希望对你有一定的参考价值。

首先建立一个备份文件夹

makedir /tmp/yum

然后备份文件

cd /etc/yum.repos.d
mv *.repo /tmp/yum

然后安装阿里源

wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-vault-8.5.2111.repo

然后清除yum缓存再重新生成yum缓存

yum clean all
yum makecache

如果报如下类似错误
Timeout was reached for http://mirrors.aliyuncs.com/centos/8/BaseOS/x86_64/os/repodata/repomd.xml [Connection timed out after 30000 milliseconds]
Could not resolve host: mirrors.cloud.aliyuncs.com
则执行如下命令

sed -i -e \'/mirrors.cloud.aliyuncs.com/d\' -e \'/mirrors.aliyuncs.com/d\' /etc/yum.repos.d/CentOS-Base.repo

参考阿里源链接:https://developer.aliyun.com/mirror/centos?spm=a2c6h.13651102.0.0.3e221b11QTXSya
