Errors during downloading metadata for repository ‘epel’:

• Status code: 404 for http://archives.fedoraproject.org/pub/archive/epel/8/Everything/x86_64/repodata/repomd.xml (IP: 38.145.60.24)
  Error: Failed to download metadata for repo ‘epel’: Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried

解决方法

404错误，估计是请求的url后面没有该文件了，一级一级找，把正确url放到 /etc/yum.repos.d/epel.repo改掉就好了
