来吧，修改源
1、进入文件目录
cd /etc/yum.repos.d
2、修改 CentOS-Base.repo
sudo vim CentOS-Base.repo
baseurl 改为如下：
[BaseOS]
name=CentOS-$releasever - Base
# baseurl=http://mirrors.cloud.aliyuncs.com/$contentdir/$releasever/BaseOS/$basearch/os/
baseurl=http://mirrors.aliyun.com/centos/8-stream/BaseOS/$basearch/os/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial
3、修改 CentOS-AppStream.repo
sudo vi CentOS-AppStream.repo
baseurl 改为如下：
[AppStream]
name=CentOS-$releasever - AppStream
# baseurl=http://mirrors.cloud.aliyuncs.com/$contentdir/$releasever/AppStream/$basearch/os/
baseurl=http://mirrors.aliyun.com/centos/8-stream/AppStream/$basearch/os/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-centosofficial
4、删除完后清除并制作缓存
dnf clean all # 清除所有的缓存文件
dnf makecache # 制作元数据缓存
5、重新 yum、dnf 命令即可
