This error usually occurs when your system is unable to connect to the CentOS mirrorlist server to download the list of available repositories. Here are some possible solutions:
1. Check your network connection: Ensure that your system is connected to the internet and that there are no connectivity issues.
2. Check your DNS settings: Ensure that your DNS settings are configured correctly. You can try changing your DNS server to a different provider, such as Google DNS or OpenDNS.
3. Check your firewall settings: Ensure that your firewall is not blocking the connection to the CentOS mirrorlist server. You can try disabling your firewall temporarily to see if that resolves the issue.
4. Manually update the mirrorlist file: You can manually update the mirrorlist file by editing the /etc/yum.repos.d/CentOS-Base.repo file and replacing the mirrorlist URL with a working one. You can find a list of mirrorlist URLs on the CentOS website.
Once you have resolved the issue, you should be able to update your system and install packages using yum without any further issues.
