centos 6.4 不能使用yum install 的問題

在青雲上創建centos 6.4後,習慣性的安裝emacs. 結果遇到報錯信息:

 

# yum install emacs
Loaded plugins: fastestmirror
Determining fastest mirrors
Error: Cannot retrieve metalink for repository: epel. Please verify its path and try again

解決方法是更新ca-certificates

 

 

# yum upgrade ca-certificates --disablerepo=epel
Loaded plugins: fastestmirror
