In this article I will show how to fix CentOS 6 error: YumRepo Error: All mirror URLs are not using ftp, http[s]

Problem

When trying update CentOS 6 with *yum update* command getting error:

Loaded plugins: fastestmirror, refresh-packagekit, security
Setting up Update Process
Determining fastest mirrors
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

Cause

CentOS 6 reached end of life on the 30th November 2020. YUM attempting connect to deprecated repositories. So, we need update deprecated repositories URL’s and point to the vault.

Resolution

To fix this problem you edit /etc/yum.repos.d/CentOS-Base.repo** and replace all mirrorlist**

  1. Go to */etc/yum.repos.d/* directory:
# cd /etc/yum.repos.d/
  1. Make copy of original file:
# cp CentOS-Base.repo CentOS-Base.repo.old
  1. Open and edit file with any text editor:
# vi CentOS-Base.repo
  1. Replace mirrorlist‘s

Replace sections:

[base]
[updates]
[extras]

With following:

[base]
name=CentOS-$releasever - Base
# mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra
# baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
baseurl=https://vault.centos.org/6.10/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

# released updates
[updates]
name=CentOS-$releasever - Updates
# mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates&infra=$infra
# baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/
baseurl=https://vault.centos.org/6.10/updates/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

# additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras
# mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras&infra=$infra
# baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/
baseurl=https://vault.centos.org/6.10/extras/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
  1. Clean yum cache
# yum clean all
  1. Run again yum update command:

# yum update
Now you can successfully update your CentOS 6.
