CSN - Fixing the CentOS 6 yum repository

CentOS 6 expired on November 30, 2020, so the repository references on your CSN must be updated to point to the vault. The file is located here:

/etc/yum.repos.d/CentOS-Base.repo
/etc/yum.repos.d/epel.repo

Use one of these methods:

Download the latest Support tools (swarm-support-tools.tgz), which includes the corrected CentOS-Base-6.repo file, and put it in your CSN’s /etc/yum.repos.d folder.
Download the epel.repo
- curl https://www.getpagespeed.com/files/centos6-epel-eol.repo --output /etc/yum.repos.d/epel.repo

OR

Edit your CentOS-Base.repo and replace its content with the following:

[base]
name=CentOS-$releasever - Base
baseurl=https://vault.centos.org/6.10/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
sslverify=0
#released updates
[updates]
name=CentOS-$releasever - Updates
baseurl=https://vault.centos.org/6.10/updates/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
sslverify=0
#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras
baseurl=https://vault.centos.org/6.10/extras/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

Edit your epel.repo and place the content with the following:
