If Debian is unable to resolve domain names, it may be due to network settings issues or DNS configuration errors. Here are some possible solutions:

  1. Check your network connection: first make sure that your connection is working properly. You can try accessing other websites or use the ping command to test the connection.
  2. Check DNS configuration: Please make sure that the DNS configuration of your Debian system is correct. You can edit the /etc/resolv.conf file to view the configuration of the DNS server and ensure that it is properly set.
  3. Update DNS servers: Try changing your DNS server settings to another reliable DNS server.
  4. To clear the DNS cache: You can try clearing the system’s DNS cache to resolve potential resolution issues. Run the command ‘sudo /etc/init.d/dns-clean restart’ in the terminal to clear the DNS cache.
  5. Restart network service: You can try restarting the network service to apply the latest DNS configurations. Run the command sudo /etc/init.d/networking restart in the terminal to restart the network service.

If none of the above methods can solve the problem, you may need to contact your network administrator or ISP for further assistance.
