Error All mirror urls are not using ftp https or file cent Fix YumRepo. 

Yum Install Update Repo Error All mirror urls are not using ftp https or file in Linux Cent OS.

If you are facing "YumRepo Error " during the yum update or package installation like this then it will definitely help you..

[root@techitadmin html]# yum -y update

"YumRepo Error: All mirror URLs are not using ftp, http[s] or file."
 Eg. Invalid release/repo/arch combination/ removing mirrorlist with no valid mirrors: /var/cache/yum/x86_64/6/base/mirrorlist txt
"Error: Cannot find a valid baseurl for repo: base" 

In order to resolve this kind of issue I would like to strongly recommend to first take backup of your old Base.repo file.

[root@techitadmin html]# cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo-bak.

Then copy and replace your existing Base.repo with this new modified repository file in your "/etc/yum.repos.d/CentOS-Base.repo". or 

Download from here CentOS-Base.repo
