Fix Failed to download metadata for repo
CentOS Linux 8 had reached the End Of Life (EOL) on December 31st, 2021.
It means that CentOS 8 will no longer receive development resources from
the official CentOS project. After Dec 31st, 2021, if you need to update
your CentOS, you need to change the mirrors to vault.centos.org where they
will be archived permanently. Alternatively, you may want to upgrade to
CentOS Stream.
Step 1: Go to the /etc/yum.repos.d/ directory.
[root@hbn ~]# cd /etc/yum.repos.d/
Step 2: Run the below commands
[root@hbn ~]# sed -i 's/mirrorlist/#mirrorlist/g'
/etc/yum.repos.d/CentOS-*
[root@hbn ~]# sed -i
's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g'
/etc/yum.repos.d/CentOS-*
Step 3: Now run the yum update
[root@hbn ~]# yum update -y
That’s it!
