If the DHCP service fails in Ubuntu, you can try the following methods to restore the DHCP service.

Restart the DHCP service.
Restart the isc-dhcp-server service using systemctl.
Check for any errors in the DHCP configuration file.
Please run the command “sudo dhcpd -t -cf /etc/dhcp/dhcpd.conf” to test the DHCP server configuration file located at /etc/dhcp/dhcpd.conf.
Check the status of the DHCP service.
Can you check the status of the isc-dhcp-server using sudo systemctl?
If the DHCP service cannot be recovered, you may need to reinstall the DHCP service.
Uninstall isc-dhcp-server using sudo apt-get remove and then reinstall it using sudo apt-get install.

By following the aforementioned steps, you should be able to restore the DHCP service and get it functioning normally again. If the issue persists, check the system logs for more detailed information and try to troubleshoot the problem.
