Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

centos下安装完EPEL源然后更新一下yum缓存如果发现这样的错误:

Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

这就表明你需要更新CA证书了,那么只需要更新CA证书就可以,不过在此同时需要临时禁用epel源并更新就可以了,命令如下:

yum --disablerepo=epel -y update ca-certificates
