Fixing “could not resolve host mirrorlist.centos.org” Error

This error message usually appears when a computer or network cannot create a connection to a certain host or domain, in this example, “mirrorlist.centos.org.” The DNS resolution is connected to this problem.

Some of the reasons for the issue include setup and network issues, Firewall or Proxy restrictions. Let’s look into some of the steps to fix the error:

1. Firstly, verify the status of the Ethernet; if it is disconnected, we must enable it.

2. The absence of a nameserver in /etc/resolv.conf could be the cause of the problem. So, check the nameserver entry.

3. Also, make sure we have a strong and current internet connection.

4. DNS-cached data can occasionally lead to problems. In order to make the computer recheck its DNS record search, we can empty the DNS cache.

5. Check the functionality of the DNS servers we are using. To test if that fixes the problem, we can try using various DNS servers.

6. Lastly, check to see if any firewall settings are preventing access to the particular domain if we are in a networked environment.
