- Status code: 404 for http://mirrors.cloud.aliyuncs.com/centos/8/AppStream/x86_64/os/repodata/repomd.xml (IP: 100.100.2.148) Error: Failed to download metadata for repo 'appstream': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried
1. 进入 yum 源目录
cd /etc/yum.repos.d/
2. 替换新的地址
for i in `ls`;do sed -i 's/mirrors.cloud.aliyuncs.com/mirrors.aliyun.com/g' $i;done for i in `ls`;do sed -i 's/$releasever/$releasever-stream/g' $i;done
3. 添加缓存
yum clean all yum makecache
