YumRepo Error: All mirror URLs are not using ftp, http[s] or file.
If you doing a yum update or yum install for CentOS 6. You might face the error:
Setting up Upgrade Process 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 retrieve repository metadata (repomd.xml) for repository: base. Please verify its path and try again
This is because YUM repository was removed from the main CentOS update servers. As a result, no security or feature upgrades are provided.
Where are these obsolete Yum Repository now? They are found in CentOS Vault Repository. To use the Vault repository, set up its repo configuration instead of the now defunct repositories configuration:

You may want to edit CentOS-Base.repo directly. My OS is CentOs 6.9
