Failed to download metadata for repo appstream

Question

Running on centos 8 today want to install new package and before it wants to run:

yum update -y

but got this:

Failed to download metadata for repo 'appstream': Cannot prepare internal mirrorlist: No URLs in mirrorlist

Then I did search and found a solution to fix it:

sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*
sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g' /etc/yum.repos.d/CentOS-*

I did this but still error persist, any idea? how to fix this? Is there new solution in 2022?

After use this solution

Now error:

Errors during downloading metadata for repository 'extras':

• Status code: 403 for https://vault.centos.org/centos/8/extras/x86_64/os/repodata/repomd.xml (IP: 13.249.9.66) Error: Failed to download metadata for repo 'extras': Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried

Answer 1

The CentOS 8 reaching its end of life, the content from the CentOS 8 repositories has been moved to vault.centos.org. Please update your CentOS yum repository paths from 'mirror.centos.org' to 'vault.centos.org' to resolve the issue.
