When you try to update or install any software inside your centos 6/7 you might will see the following issues
YumRepo Error and Cannot find valid baseurl
To fix this issue you need to login to your server using ssh software such as putty
Problem
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 of this error here is not an issue with your OS but the EOL of using this linux template has reached to the end of the life
So we are going to update the links inside SSH
The Solution:
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/
2. Make copy of original file:
# cp CentOS-Base.repo CentOS-Base.repo.old
3. Open and edit file with any text editor:
# vi CentOS-Base.repo
4. 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
5. Clean yum cache
# yum clean all
6. Run again yum update command:
# yum update
Now you can successfully update your CentOS 6.
