Cannot open/read repomd.xml file for repository: macromedia
failure: repodata/repomd.xml from macromedia: [Errno 256] No more mirrors to try.
Error: failure: repodata/repomd.xml from macromedia: [Errno 256] No more mirrors to try.

它是不是要在一些网站上去下载文件.
其中 No more mirrors to try.
是不是要修该一些文件, 请提供一些 "mirrors" 给我,并告诉我要修改哪些文件.

非常感谢.
