Jack Posted February 25, 2022 Share Posted February 25, 2022 (edited) 現在使用CentOS 8.0 ~ 8.5 敲指令時，應該會發生問題 sudo yum update 例如：阿里雲的主機 Errors during downloading metadata for repository 'AppStream': - 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 這需要更換源 網路搜尋後，你可以找到 centos yum 更換源 的解決方法 但建議不要使用CentOS 8.0 ~ 8.5 Edited February 25, 2022 by Jack Link to comment Share on other sites More sharing options...
