Solution

This solution involves verifying DNS configurations, updating the `/etc/resolv.conf` file with reliable DNS servers, and restarting the network services to resolve issues with domain name resolution.


1. Check Internet connection


ping 8.8.8.8
2. Check & Modify DNS Server Configuration
cat /etc/resolv.conf
sudo nano /etc/resolv.conf
add nameservers to resolve.conf
nameserver 8.8.8.8
nameserver 8.8.4.4

13. Restart networking


sudo systemctl restart networking

14. Check if its working now


ping google.com
