The error message “No DHCPOFFERS received” indicates that the DHCP client (dhclient) did not receive any DHCP offers from a DHCP server on your network. This can happen if there is no DHCP server available or if there are configuration issues with the DHCP server.
Here are a few steps you can try to troubleshoot this issue:
Verify DHCP server availability: Ensure that there is a properly functioning DHCP server on your network. Check if other devices on the same network segment are able to obtain IP addresses via DHCP.
Check network connectivity: Make sure your network connection is working properly and there are no connectivity issues between your machine and the DHCP server. Verify that the cable is securely connected and try pinging other devices or accessing the internet to confirm network connectivity.
Check firewall settings: Ensure that any firewalls or security settings on your machine or network aren’t blocking DHCP requests or responses.
Restart networking services: Try restarting the networking service or network manager on your system using appropriate commands for your operating system:
- On Ubuntu/Debian-based systems:
sudo systemctl restart networking
- On CentOS/RHEL-based systems:
sudo systemctl restart NetworkManager
- On Ubuntu/Debian-based systems:
If none of these steps resolve the issue, you may need to further investigate your network setup or contact your network administrator for assistance in troubleshooting the DHCP problem.
